We build the Node.js backends, APIs, and tooling behind React and React Native products, so one team and one language cover the whole stack. ## Feature Development - React Foundation Founding Member · 300+ commits to React Native · Contributing since 2016 - 100+ Enterprise projects delivered - Industry runs on our tooling · 50M+ OSS downloads / month - 3.7× Lower task cost vs Opus 5.5 - “With the release of Re.Pack 5 we now have an easy way to create the MiniApps and federated mobile apps that our users have been asking for.” — Zackary Chapple, CEO / Zephyr Cloud - ~6x Faster prototyping · 60+ Components mapped with full coverage · Figma · Claude · Server · Tailwind · Tokens · React · Cursor · ESLint - React Native Paper · A component library in our open-source toolkit for building React Native interfaces. ## What you get: Ship the whole stack in TypeScript. - **Production-grade APIs** REST, GraphQL, and real-time services designed around the clients that consume them. - **Backend-for-frontend layer** BFFs that shape data per platform, so mobile clients stay thin and screens load in one round-trip. - **Shared types end to end** One TypeScript contract from database to UI, so API changes fail at compile time, not in production. - **Tooling and automation** CLIs, build scripts, and internal services on the runtime your team already knows. - **Performance under load** Profiling, caching, and scaling that keep response times flat as traffic grows. - **Observability built in** Logging, tracing, and metrics from the first deploy, so production issues are debuggable. ## How we work together: Turn roadmap scope into shipped features. ### Extend your team (1 week) Our senior engineers join your team to ship features, guide technical decisions, and strengthen delivery. - Your roadmap and workflow - Expertise shared as we work - Flexible timezone coverage ### Deliver a project (1-12 months) We take agreed work from technical planning to release, with clear responsibilities and progress you can see. - 3 Callstack engineers ship like 6 - Impact visible before sprint two - End-to-end delivery ### Solve specific challenge (as needed) We address a performance, migration, or infrastructure challenge, or run training around your team’s needs. - Focused reviews or implementation - Knowledge your team keeps - Outcomes guaranteed with contract ## What shipping at AI speed looks like. - [React Universe App: Networking Evolved With Liquid Glass](/case-studies/react-universe-app-networking-evolved-with-liquid-glass): 63% adoption rate; majority of attendees registered in the app - [Building a browser-based React Native playground for Expo](/case-studies/building-a-browser-based-react-native-playground-for-expo) - [Migrating AutoZone’s Storefront to Next.js for Better Performance and SEO](/case-studies/migration-to-nextjs-for-autozone): #1 SEO rank, recovering from 3-9 - [Creating React Native SDK Wrapper for Rive](/case-studies/creating-react-native-sdk-wrapper-for-rive): 100k weekly downloads on npm **One team. Whole stack.** We build the Node.js services behind your product with the same rigor as the apps that consume them. [Book a call](/contact) > We had been struggling with React Native application performance until we met Callstack. > > — Huỳnh Chí Hùng, Associate Director, MOMO We’ll connect you with the right expert within 24 hours. ## Let’s find the right path for your product. **Which Node.js frameworks do you use?** We work with NestJS, Fastify, Express, and serverless runtimes. The choice follows your requirements and team experience, not our preferences. **Can you take over an existing backend?** Yes. We audit the current service, stabilize the risky parts, and evolve the architecture incrementally while it keeps serving traffic. **Do you build serverless or containerized services?** Both. Serverless fits spiky, event-driven workloads; containers fit steady traffic and long-lived connections. We model cost and latency before choosing. **How does this connect to our React Native app?** We design the API around the app: a BFF per platform where it pays off, shared TypeScript types, and contracts that catch breaking changes in CI. **Do you handle databases and infrastructure?** Yes. Schema design, migrations, and deployment on your cloud, with infrastructure as code so the setup is reproducible. **Can agents work on the backend too?** Yes. The same AI-native workflows we use for app code apply: agents implement and test changes, engineers own architecture and review. ## Open source - [React Native Paper](https://github.com/callstack/react-native-paper): Material Design for React Native (Android & iOS) - [React Native Bottom Tabs](https://github.com/callstackincubator/react-native-bottom-tabs): Native Bottom Tabs for React Native - [React Navigation](https://github.com/react-navigation/react-navigation): Routing and navigation for your React Native apps - [Liquid Glass](https://github.com/callstack/liquid-glass): iOS Liquid Glass in React Native - [Voltra](https://github.com/callstackincubator/voltra): Voltra lets React Native developers build native iOS Live Activities, Dynamic Island layouts, and widgets as React components without writing Swift.
