Reflex
Reflex is a full-stack Python platform for building, deploying, and managing web applications and internal tools. Teams can describe an app in natural language or write Python directly, then ship production frontends, backends, and hosted deployments from one place instead of stitching together separate frameworks, JavaScript stacks, and infrastructure tools.
The open-source Reflex framework (Apache 2.0) compiles Python into a React frontend and a Starlette backend. Developers work with reactive state, 60+ built-in components, and the option to wrap any React library. The platform also includes an AI app builder, MCP and Skills support for coding agents, and one-click deployment with versioning, logs, and rollback.
Reflex is built for Python developers, data teams, and enterprises shipping internal dashboards, AI apps, and customer-facing tools. Companies including Autodesk, Dell, and Fastly use it to deliver full-stack apps without hiring dedicated frontend engineers. Hosted plans range from a free tier with framework access and limited credits to Pro and custom Enterprise options with team workspaces, SSO, and on-prem deployment.
Write the entire stack in Python, from UI components to backend APIs
Open-source framework compiles to React and Starlette under the hood
Describe your app and the AI builder generates production-ready Python code
MCP and Skills let Claude Code, Cursor, and other agents build on Reflex
Deploy with one click, roll back versions, and manage secrets from one dashboard
60+ built-in UI components, plus wrap any React library in a few lines of Python
First-class integrations for OpenAI, Anthropic, Stripe, Supabase, and 25+ services
Build full-stack web apps entirely in Python with no JavaScript required.
Open-source Apache 2.0 framework you can self-host or deploy to any cloud.
Free tier includes the framework, 50 monthly credits, and one hosted app.
Every Reflex app exposes an MCP so agents can interact via API instead of browser automation.
SOC 2 certified platform with SSO, RBAC, and on-prem deployment on Enterprise plans.
Pro plan costs $200 per month, which may be steep for solo hobbyists.
Free tier limits you to one hosted app and 50 monthly credits.
Enterprise features like SSO, RBAC, and HIPAA BAA require a custom Enterprise plan.
Requires Python comfort; less approachable than no-code tools for non-developers.
Is Reflex free to use?
Yes. Reflex offers a Free plan that includes the open-source framework, 50 monthly credits for AI building and hosting, one hosted app, MCP and Skills access, and community support via Discord and GitHub. Paid Pro and Enterprise plans add more credits, hosted apps, and team features.
Do I need to know JavaScript to use Reflex?
No. Reflex lets you build full-stack web applications entirely in Python. The framework compiles your Python code into a React frontend and Starlette backend automatically, so you do not need to write JavaScript or HTML to ship a production app.
Is the Reflex framework open source?
Yes. The Reflex framework is open source under the Apache 2.0 license. You can view the source on GitHub, contribute to the project, and self-host or deploy your apps to any cloud without vendor lock-in.
Can I deploy Reflex apps to my own cloud?
Yes. Reflex apps are standard Python and can run on Reflex Cloud with one-click deploy, or on your own AWS, GCP, Azure, Databricks, or on-prem infrastructure. Enterprise plans include deploy-to-any-cloud support and VPC or air-gapped deployment options.
Does Reflex work with AI coding tools like Cursor?
Yes. Reflex provides an Agent Toolkit with MCP and Skills integrations designed for AI coding assistants including Cursor and Claude Code. The platform documentation states that these tools produce higher-quality Reflex apps with fewer errors when building through MCP.
What integrations does Reflex support?
Reflex includes first-class integrations for services such as OpenAI, Anthropic, Stripe, Supabase, AWS, Databricks, GitHub, Notion, HubSpot, Twilio, and Hugging Face. You can also connect any Python SDK, library, or API to extend your app beyond the built-in connectors.
How much does Reflex Pro cost?
Reflex Pro is priced at $200 per month and includes everything in the Free plan plus 2,000 monthly credits, 10 hosted apps, custom domains, private projects, and app code download. Enterprise pricing is custom and requires contacting the Reflex sales team.
