Every change, backed by git
Every AI change, every human change — committed to a real git branch with a message and an author. Full history, branches, rollback to any version. Audit-ready out of the box.
Build with AI. Ship with confidence.
The AI app builder with built-in testing and production Python code you own.

Read all storiesHow it works
Describe, build, test, and ship it
From an idea to a tested, production-ready Python app in four steps.
Describe what you want
Start with a prompt, document, or screenshot.
Watch it come to life
Build your app with AI and see changes live.
Test before you ship
Review AI-generated tests or add your own.
Deploy anywhere
Ship to Reflex Cloud or your own infrastructure. On Enterprise, the builder runs there too.
Testing
AI-assisted testing, built in
AI suggests tests automatically. You review, customize, or add your own.
The agent writes the tests
AI suggests pytest, browser, and UI tests. Review and customize them for your app.
Catch regressions before they ship
Run the full suite on every build and see which changes need attention before release.
Code you can trust
Production code you own
Every app outputs clean, readable Python backed by git.
Code your team would actually approve
Reflex apps output idiomatic Python with type hints, docstrings, and the patterns your senior devs would use. Built on the open-source framework teams at Amazon and Dell ship on. Apache 2.0 — you own the code.

Integrations
Connect to your systems
Your databases, your APIs, and your internal libraries, not just pre-built SaaS integrations.
01
Pre-built and tested
The agent uses tested abstractions for every integration. Same implementation, every time — so what works on your laptop works in production, and what works for one teammate works for the next.
02
Or any Python package
Pre-built isn't the limit. Reflex is Python, so the agent can use anything on PyPI or your private registry.
Collaboration
Bring your whole team in
Technical and non-technical, working on the same codebase.
One codebase, two editors
Your engineer ships with Claude Code and MCP from a terminal. Your PM builds in the visual web builder. Same project, same branches, same test suite — nobody re-implements anything.
Roles built for real teams
Admins set integrations and guardrails, and builders create within them. On Enterprise, viewer seats let stakeholders review and use apps without builder access.
Build your first app with AI.
Describe it, review the tests, and ship Python code your team owns.
