## Full-stack Python web apps with Reflex—no JavaScript required

Production web applications built in pure Python—complex state, database integration, and deployment included.

## When Python teams want a full web product without JavaScript

Reflex lets Python teams build interactive, production-grade web applications without writing a line of JavaScript or JSX. Unlike Streamlit or Gradio, Reflex is designed for full applications with routing, forms, complex state machines, and database backends—not just visualisation tools or model demos. We help teams architect, build, and deploy Reflex applications that can grow beyond the initial proof of concept.

## What we deliver

- **State architecture and component design**: We design the state graph upfront—which state lives globally, which is local to a component, and how side-effects are isolated—so the app stays predictable as it grows.
- **Database backend and API integration**: SQLAlchemy or async ORM integration, background tasks, external REST/GraphQL API calls, and proper connection pooling for concurrent users.
- **Production deployment and CI/CD**: Docker builds for Reflex's frontend and backend separation, reverse proxy configuration, WebSocket scaling, and automated deploys from your repository.

## Engineering standards in production

How we keep full-stack Reflex applications predictable and testable

- **State isolation and testing**: Unit tests on state event handlers independent of the UI, so business logic is verifiable without a browser.
- **WebSocket reliability**: Connection drop handling, reconnect logic, and server-sent state diffing tuned so the app recovers gracefully—not just in the happy path.
- **Build and bundle hygiene**: Reflex compiles to React under the hood. We verify that production builds are slim, dependencies are pinned, and the frontend/backend deploy atomically.

## When engagement makes sense

- **A real web product in pure Python**: When you need routing, auth, forms, real-time updates, and a database backend—but your team is Python-native and wants to stay that way.
- **Replacing a React or Next.js prototype**: When a frontend was built by contractors and the Python team cannot maintain it—Reflex lets you own the full stack again.
- **AI-native product interfaces**: When streaming LLM responses, real-time pipeline status, or agent feedback loops need a proper reactive UI, not an embedded chat widget.

## FAQ

- **Is Reflex production-ready?**: For most web application use cases—yes. It is not yet ideal for high-traffic public sites that need SSR and CDN edge delivery. We assess fit honestly before any project starts.
- **Can Reflex replace Django or FastAPI?**: For UI-heavy applications—often yes. For pure APIs or heavy background processing, Django/FastAPI remain better choices. Reflex can call FastAPI endpoints.
- **Fixed price?**: For a defined feature set—yes. Applications that evolve post-launch suit a retainer or phased engagement.
