8 best progressive web app development companies in 2026 (vetted shortlist)

Most vendors that say they build PWAs are shipping a website with a manifest file. The Lighthouse PWA audit passes. The app installs to the home screen. Then the service worker caches nothing useful, push notifications fail silently on older iPhones, and the offline experience is a white screen with "No connection." The gap between "installs to home screen" and "works offline when it matters" is where bad vendors hide. That gap is what this list filters for.

The eight PWA development companies on this list are thoughtbot, Marmelab, RaftLabs, Miquido, Yalantis, Scandiweb, ELEKS, and SoftServe. RaftLabs is on this list. We wrote our own entry with the same directness we applied to everyone else.

How we evaluated this list

No company paid for placement on this list.

1. thoughtbot

thoughtbot is a Boston-based product studio founded in 2003. Their model is quality-first: design, engineering, and project management work as one team rather than three sequential handoffs. For businesses where the web experience is the product itself, not a feature added to a backend system, that integration produces a different kind of deliverable than most shops offer.

Their web practice runs on React and TypeScript. Service workers, offline caching, and Web App Manifests are part of every standard build. They publish openly about their engineering decisions, which gives any technical team an independent view of their standards before signing a proposal. The real signal for a PWA firm is not the client list. It is whether the firm can explain, specifically, how they handle cache invalidation on deploy and what the service worker update lifecycle looks like for users mid-session. thoughtbot can answer that.

The open-source output and public writing give any technical hiring manager a concrete view of how they make decisions before a dollar is committed. Teams that write publicly about hard tradeoffs are teams that surface those tradeoffs before they become production incidents.

Notable work -- thoughtbot has shipped consumer-facing web applications for health tech, SaaS, and fintech companies. Their case studies document specific problems identified in discovery, specific architectural decisions made to solve them, and specific retention or conversion outcomes. Clients consistently describe a team that surfaces problems before they become engineering issues.

Pricing signal -- $175-$250/hr. Engagements typically start at $100K-$150K. The rate reflects a team where every engineer participates in design review and every decision traces back to a defined product outcome. Not calibrated for projects under $80K.

What to watch -- thoughtbot is the right choice when the web experience itself is a competitive differentiator. For internal enterprise tools, backend-heavy platforms where the interface is functional rather than brand-defining, or projects with a budget ceiling below $100K, the overhead is not justified.

• Best for: Consumer product companies and SaaS businesses that need design-engineering parity and senior-level involvement on every workstream

• Specialization: React, TypeScript, Ruby on Rails, product design, PWA architecture

• Pricing: $175-$250/hr, engagements from $100K

• Clutch: 4.9/5 (Clutch)

2. Marmelab

Marmelab is a Paris-based studio of 22 engineers, averaging 10 years of experience per developer, with 12+ years building React-based web applications. They created react-admin, the open-source framework for admin interfaces and internal tools, which carries 26,000 GitHub stars and is maintained by teams worldwide. That project is a direct view of how Marmelab approaches code quality, documentation, and long-term maintainability. Open-source is harder to fake than a case study PDF.

Their client work runs on React, Node.js, and TypeScript. They have built platforms for Accor (Europe's largest hotel group), ARTE (European cultural broadcaster), Canal+, TF1, and BpiFrance. These are organizations where reliability and sustained performance are non-negotiable and the user base is measured in millions. When a firm can maintain a 26,000-star open-source project for a decade, their service workers are deliberate. Their caching strategies are planned. Their update lifecycles are documented.

Teams that can build and sustain open-source infrastructure at that scale are applying the same discipline to every PWA they ship for clients.

Notable work -- Marmelab built digital products for Accor, Canal+, TF1, ARTE, and BpiFrance. Their open-source track record with react-admin gives any technical hiring manager a concrete view of how they write code in public. Teams that maintain a 26,000-star project write the same quality of service worker they write for every client engagement.

Pricing signal -- $100-$149/hr. Projects typically run $80K-$400K. Competitive for US and UK companies seeking European-timezone collaboration at rates meaningfully below US market pricing with a senior-to-junior ratio that boutique studios cannot match.

What to watch -- Marmelab is 22 people. Capacity is limited. Programs requiring 20+ parallel engineers or multiple simultaneous workstreams are outside what they take on. For focused product builds where senior judgment on every decision matters more than team size, that constraint becomes an advantage.

• Best for: Product companies that want open-source-grade engineering discipline and senior React expertise without the overhead of a larger agency

• Specialization: React, Node.js, TypeScript, PWA architecture, open-source tooling

• Pricing: $100-$149/hr, projects from $80K

• Clutch: 4.9/5 (Clutch)

3. RaftLabs

RaftLabs builds progressive web apps for mid-market businesses. The model is structured differently from most shops: a scoping engagement before any build, fixed-price delivery, and one team that owns architecture, development, QA, and deployment from start to finish. No strategy-then-handoff. No open-ended time-and-materials billing.

Production PWAs have shipped across hospitality, eLearning, food service, and community platforms. The technical stack covers Service Workers and IndexedDB for offline-first architecture, the Web Push API for notifications, and installable Web App Manifests calibrated for iOS and Android home screen installation. PWA migration is also within scope: adding offline, push, and install capabilities to an existing web app without touching the core application. The scoping engagement runs two to four weeks and produces a fixed-price proposal before any development starts. If a native app would serve the use case better than a PWA, that answer comes out of scoping.

The most common mistake mid-market teams make is building the installable shell before defining the offline behavior. An app that installs but shows a white screen when the network drops delivers a worse experience than the mobile website it replaced. Caching strategy, offline fallback content, and sync queue behavior are defined before a line of service worker code is written.

Notable work -- RaftLabs has delivered PWA projects for clients including Wyndham Hotels in hospitality, Vodafone and T-Mobile in telecom, and mid-market platforms across multiple verticals. A community events PWA with offline-first architecture and push notifications reached 50,000 users in 14 weeks. A food order management PWA replaced separate iOS and Android apps for a restaurant group, eliminated order errors, and tripled revenue in year one. An eLearning platform migration added a Service Worker, manifest, and offline layer to an existing web app without a full rewrite; that platform now serves 5,000+ daily active users.

Pricing signal -- $29-$49/hr. A production PWA with offline support, push notifications, installable manifest, and backend API typically runs $20K-$80K depending on scope. Fixed-price means the proposal price is the delivery price.

What to watch -- RaftLabs works best when you need the full build: PWA architecture and engineering in one team. If you need only a point solution or a single-feature addition, a more specialized vendor may be faster. Programs needing 20+ concurrent engineers across parallel workstreams are outside our capacity.

• Best for: Mid-market businesses ($1M-$100M revenue) needing a production-grade PWA delivered by one accountable team at a fixed price

• Specialization: Service Workers, IndexedDB, Web Push, offline-first architecture, PWA migration from existing web apps

• Pricing: $29-$49/hr, fixed-price engagements

• Clutch: 4.9/5 (50+ verified reviews)

4. Miquido

Miquido is a Krakow-based digital product studio with 200+ engineers, 15 years of delivery history, and Google-certified partner status. The Financial Times has listed them among Europe's fastest-growing companies. Their client base spans TUI, Skyscanner, BNP Paribas, Aviva, HelloFresh, Warner Recorded Music, and Abbey Road Studios. That range reflects the compliance requirements and performance standards their teams work against daily.

Their web and mobile practice covers React-based frontends, backend APIs, and AI integration. PWA development sits within their web engineering work. Service workers, progressive enhancement, and installable manifests are standard for clients that need cross-platform reach without separate iOS and Android codebases. Nine in ten Miquido projects come from client referrals. That is the clearest independent signal of whether what ships meets expectations.

Time Magazine recognition and multiple Lovie and Webby awards signal a design-engineering standard that runs above average for their price point. That matters when the PWA is a consumer-facing product where visual quality is part of the retention story.

Notable work -- Miquido delivered products for TUI, Skyscanner, BNP Paribas, Aviva, HelloFresh, and Warner Recorded Music. Their awards across the Lovie and Webby programs signal a design-engineering standard above average for their price point. Ninety percent of projects come from referrals.

Pricing signal -- $50-$99/hr. Projects typically run $75K-$500K. Competitive for US and UK companies seeking design-quality web and PWA development at rates below US market pricing.

What to watch -- Miquido's model is built around longer-running product engagements rather than single-phase builds. Teams that need a focused eight-week PWA build without a broader product program may find themselves over-resourced for the scope. Clients with ongoing product development road maps get the most from the relationship.

• Best for: Mid-to-large businesses building cross-platform web products that require GDPR compliance, strong UX, and a team ready to integrate AI as the product evolves

• Specialization: Web app development, mobile-first PWA, AI integration, product design

• Pricing: $50-$99/hr, projects from $75K

• Clutch: 4.9/5 (Clutch)

5. Yalantis

Yalantis is a software development firm based in Kyiv with delivery teams in the US and Europe. They have built enterprise mobile and web applications for Samsung, Duolingo, and Waze since 2008. Their practice spans frontend development, mobile engineering, and backend infrastructure. That combination makes them a credible option for PWAs where the web frontend and a complex backend need to be co-designed, not connected as an afterthought.

Their frontend team works in React and Angular. Offline-capable architectures, service workers, and cross-platform web delivery are part of their documented capability. The differentiator is engineering depth on both sides of the stack: they can build or extend the API infrastructure a production PWA depends on, not just the client layer. For teams where the backend is as complex as the frontend, that matters.

Their case studies describe architectural decisions and measurable outcomes rather than client logo lists. Teams that have shipped at Samsung and Waze are working against a performance bar that most agency portfolios do not reach.

Notable work -- Yalantis built mobile and web platforms for Samsung's developer tools ecosystem and contributed to Waze's technical infrastructure. Their case studies document specific architectural decisions and measured outcomes. Performance-bar clients like Samsung and Waze require verified engineering standards, not approximate ones.

Pricing signal -- $50-$99/hr. Projects typically run $75K-$600K. Particularly competitive for US companies that need enterprise-grade web engineering at rates well below US market pricing.

What to watch -- Yalantis is strongest when the engagement involves significant backend complexity alongside frontend development. Pure PWA frontend builds without a backend component are within their scope but do not take full advantage of their differentiation.

• Best for: Enterprise teams building PWAs with complex backend integrations, real-time data pipelines, or multi-service architecture

• Specialization: React, Angular, Node.js, PWA development, enterprise backend integration

• Pricing: $50-$99/hr, projects from $75K

• Clutch: 4.9/5 (Clutch)

6. Scandiweb

Scandiweb is a Riga-based digital retail firm with 600+ employees across 36 countries and 20+ years building e-commerce platforms. They are among the most experienced PWA development teams on this list for one specific context: high-traffic online stores that need headless frontend delivery, offline browsing, and app-store-like install prompts on mobile devices.

Their technology stack centers on Adobe Commerce (Magento), Shopify, Salesforce Commerce Cloud, and headless CMS platforms including Sanity. Progressive web storefronts and custom React frontends sit at the center of their modern frontend practice. With 500+ clients including BMW, they have production evidence that their PWA implementations hold up under real traffic, not prototype conditions. Client-reported outcomes include 3-4x performance improvements after migrating from traditional server-rendered storefronts to React-based PWAs.

For e-commerce specifically, Scandiweb's domain depth means they have seen the edge cases that general-purpose firms encounter for the first time. Cart persistence in offline mode. Session recovery when the network drops mid-checkout. Catalog caching strategies that don't serve stale product data.

Notable work -- Scandiweb delivered progressive web storefronts for BMW and major retail brands. Client-reported outcomes include 3-4x performance improvements after migrating from server-rendered storefronts to React-based PWAs. Their 4.9/5 Clutch rating across a large review base reflects consistent delivery at volume.

Pricing signal -- $50-$99/hr. E-commerce PWA projects typically run $50K-$300K depending on platform complexity and integration requirements. Competitive for retailers migrating from legacy Magento or Shopify themes to headless PWA storefronts.

What to watch -- Scandiweb's expertise is tightly focused on e-commerce. PWA builds outside of retail, wholesale, or digital storefronts will not benefit from the same domain depth. Outside that vertical, a generalist firm will give more relevant experience.

• Best for: E-commerce businesses migrating to a headless PWA storefront on Magento, Shopify, Salesforce Commerce Cloud, or SAP Commerce Cloud

• Specialization: E-commerce PWA, Adobe Commerce, Magento PWA Studio, headless commerce, React storefronts

• Pricing: $50-$99/hr, projects from $50K

• Clutch: 4.9/5 (Clutch)

7. ELEKS

ELEKS is a global software engineering firm headquartered in Lviv, Ukraine, with 2,000+ specialists and offices across the US, UK, and Europe. They have delivered 1,000+ projects since 1991 and maintain an average client relationship of 20+ years. That longevity matters for multi-phase web platform engagements where team continuity directly affects the outcome.

Their practice covers custom application development, cloud engineering, and enterprise software modernization. PWA capability sits within their web application engineering work. The evidence of quality shows up in specific client outcomes: a platform serving 2 million members for David Lloyd Clubs across 130 locations, enterprise investment accounting software for BNY Mellon, and logistics tools for DPD and ESET. Ninety percent of customers return for a second engagement.

For enterprise programs where a PWA is one component of a larger digital platform rather than the entire delivery, ELEKS' breadth across backend engineering, cloud infrastructure, and compliance requirements is a real advantage. They are not a one-trick front-end shop.

Notable work -- ELEKS built a platform for David Lloyd Clubs serving 2 million members across 130 locations. Their enterprise software work spans financial services, logistics, and health technology with documented outcomes across 120+ active client accounts. A 90% client return rate is the clearest independent signal of delivery quality at scale.

Pricing signal -- $50-$99/hr. Enterprise application projects typically run $100K-$1M+ depending on integration scope and team composition. Large-scale programs benefit from their multi-team delivery model at a cost well below tier-one consultancies.

What to watch -- ELEKS is enterprise-calibrated. The engagement model, process overhead, and minimum team structures are designed for programs at $150K+. Focused PWA builds under $100K will find a leaner firm delivers a better result at a lower total cost.

• Best for: Enterprise businesses building or modernizing web platforms at scale with significant backend integration, compliance, or multi-system architecture requirements

• Specialization: Custom web application development, enterprise software, cloud infrastructure, PWA architecture

• Pricing: $50-$99/hr, projects from $100K

• Clutch: 4.8/5 (Clutch)

8. SoftServe

SoftServe is a global technology firm headquartered in Austin, Texas, with delivery centers in Ukraine and across Eastern Europe. With 12,000+ engineers, they operate at a size where enterprise clients can allocate large, dedicated teams to complex digital programs without the staffing risk of firms that need to stretch their roster to fill a project.

Their Digital Products and Services practice covers web application development, UI/UX design, and product strategy. PWA development is within their web engineering capability. Service worker architecture, offline-first delivery, and installable web apps are standard outputs from their enterprise frontend teams. Fortune 500 companies use them because their delivery model can scale to programs that boutique firms cannot staff.

The procurement filters that large companies apply tend to surface firms with consistent records rather than large portfolios. SoftServe passes those filters because their delivery model is built for the formal governance, SLA requirements, and multi-vendor coordination that enterprise digital programs require.

Notable work -- SoftServe has delivered digital products for healthcare, financial services, and technology companies at Fortune 500 scope. Their client roster includes enterprise organizations where delivery variance has operational consequences and vendor continuity is a procurement requirement.

Pricing signal -- $50-$99/hr. Enterprise digital programs typically run $200K-$2M+ depending on team size and program scope. Smaller focused builds are within their technical capability but are not where their delivery model differentiates.

What to watch -- SoftServe is calibrated for enterprise scale. The engagement model is built for programs that need 10-50+ engineers, multi-phase delivery, and formal vendor management structures. Companies that need a fast-moving, focused PWA build will find a leaner firm delivers a better result at a lower total cost and without the process overhead.

• Best for: Fortune 500 and large enterprise companies running multi-team digital programs where delivery scale and operational continuity matter

• Specialization: Enterprise web application development, digital product strategy, cloud engineering, PWA at scale

• Pricing: $50-$99/hr, programs from $200K

• Clutch: 4.8/5 (Clutch)

Side-by-side comparison

The question that separates PWA product studios from PWA delivery firms

The most common mistake buyers make is treating all PWA vendors as interchangeable. They evaluate by portfolio size, Clutch rating, and rate card, then choose based on which pitch deck felt most polished. The actual filter is whether the firm has shipped a PWA that works offline for real users under real network conditions, not whether they have a "PWA" checkbox in their service list.

Product studios like thoughtbot and Marmelab treat PWA architecture as part of product thinking. They work best when the web experience is the product itself, not a channel. They will rethink the offline experience from scratch if that is what the product requires. Their output is a web experience that users choose over native apps because the quality is that high. Their price reflects that.

Delivery firms like RaftLabs, Miquido, and Yalantis work best when the scope is defined, the business outcome is measurable, and the buyer needs a team that executes reliably rather than one that reimagines the product. Fixed-price models work here because the architecture decisions are straightforward enough to estimate at the start, not emergent. Enterprise firms like ELEKS and SoftServe serve a third category: programs where team scale, vendor continuity, and formal delivery governance matter more than speed or creative output.

Getting the model wrong is more expensive than getting the vendor wrong.

"These apps aren't packaged and deployed through stores, they're just websites that took all the right vitamins."

-- Alex Russell, Chrome Engineering, Google (2015, "Progressive Web Apps: Escaping Tabs Without Losing Our Soul")

Google's published developer case studies show what those vitamins produce in practice. After launching a PWA, Alibaba documented a 76% increase in total conversions across browsers, a 14% increase in monthly active users on iOS, and a 30% increase in monthly active users on Android. Pinterest rebuilt as a PWA and reported a 60% increase in core engagement. These are not pilot results. They are production outcomes from firms that pushed the architecture to its production limits and documented what happened. The gap between a website with a manifest file and a production-grade PWA with offline-first architecture is where those numbers live.

Five questions to ask before signing

1. Can you share a Lighthouse report from a production PWA you currently maintain? Not a demo URL. Not a localhost report. A live domain you can audit yourself in Chrome DevTools. Run the Lighthouse PWA audit: check for a valid service worker, a passing Web App Manifest, and an HTTPS connection. Then check Performance. A firm that cannot share a live, auditable PWA link has not shipped one, or has not maintained what it shipped past handoff.

2. What is your service worker caching strategy, and how do you handle cache invalidation on deploy? Service workers that cache aggressively can leave users running stale JavaScript and stale UI after a production deploy. Ask specifically: what caching strategy do they use per asset type (network-first, cache-first, stale-while-revalidate), how they handle the service worker update lifecycle, and what the user experience is when a new version is available mid-session. Vague answers about "offline support" indicate a team that added a boilerplate service worker without planning for the deployment cycle.

3. How do you handle iOS push notification limitations? Web Push on iOS requires iOS 16.4 or later, requires the user to add the app to their home screen first, and only works in Safari. Chrome, Firefox, and Edge on iPhone cannot receive web push notifications as of 2026. Ask how any vendor handles this gap. A firm that says "iOS is fully supported" without those caveats has not shipped a PWA where iOS push notification delivery needed to be debugged in production.

4. What does offline look like when a user opens the app cold with no network connection? There are two kinds of offline support. The first is a branded "you are offline" error page. That is better than a browser error, but it is not offline-first architecture. The second is an app that loads from cache, displays previously fetched data, accepts user input, and queues writes for sync when the connection returns. Ask to see the offline experience for a production PWA they maintain. Ask whether IndexedDB or the Cache API is used for data, and how the sync queue handles writes that happened while offline.

5. Who owns the service worker after launch, and what is the process for a safe update rollout? A broken service worker update can leave users stuck on a stale cached version or produce errors mid-session if the cache and the application code diverge. Ask specifically: who manages the service worker lifecycle after handoff, what the process is for pushing a service worker update safely, and how they monitor for service worker registration failures in production. A team with no defined process for this is delivering a technical liability alongside the build.

The verdict

thoughtbot for consumer product companies where the web experience is a competitive differentiator and budget starts at $100K. Marmelab for teams that want open-source-grade React discipline from a senior European boutique at rates below US market pricing. RaftLabs for mid-market businesses that need a production-grade offline-first PWA at a fixed price from one team that owns architecture, development, and deployment. Miquido for longer-running product programs where AI integration is on the road map and GDPR compliance is a hard requirement. Yalantis for enterprise PWAs where the backend is as complex as the frontend and co-design across both layers matters. Scandiweb for e-commerce businesses migrating to a headless PWA storefront on Magento, Shopify, or Salesforce Commerce Cloud. ELEKS for enterprise web platform programs that need team continuity across years, compliance requirements across systems, and a vendor that has been doing this since 1991. SoftServe for Fortune 500 programs where delivery scale and formal governance matter as much as technical execution. Match the firm to the actual work, not to the largest client logo in their portfolio.
