Describe, build, test, and ship it
From an idea to a tested, production-ready Python app in four steps.
Describe what you want
Give a prompt, upload a PRD, or screenshot an existing app to recreate it.
Watch it come to life
AI builds your app in real-time with live preview. Agent researches the web, reads docs, figures out integrations.
Test before you ship
The builder suggests tests automatically after each feature. You review, customize, or add your own.
Deploy anywhere
One-click deploy to Reflex Cloud, your cloud, or on-prem.
AI-assisted testing, built in
AI suggests tests automatically. You review, customize, or add your own.
The agent writes the tests
AI builder suggests and writes the pytest, browser, or UI test for you. The agent doesn't ship code it can't verify.
Catch regressions before they ship
Every build runs the complete suite. Historical pass rates indicate if the latest change caused any issues, ensuring you ship the prototype to production.
Connect to your systems
Your databases, your APIs, your internal libraries — not just pre-built SaaS integrations. Any Python package works.
Pre-built integrations, pre-vetted
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.
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. Lovable and v0 can't say that.
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. Builders create within them. Viewer seats let stakeholders review and interact with apps — no deploy, no separate staging environment, no extra license.
Production code, not AI slop
Every app outputs clean, readable Python backed by git.
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.
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 framework Amazon, NASA, and Dell ship on. Apache 2.0 — you own the code.
—“Reflex definitely saved us from needing to hire a frontend engineer and sped us up by 4x relative to learning React.”
