Prompt to production app, in Pure Python
Reflex is the open-source framework empowering Python developers to build web apps faster. Build both your frontend and backend in a single language, Python (pip install reflex), with no JavaScript or web development experience required. Our mission is to simplify web development by creating an ecosystem of open-source tools and hosted services that enable Python developers to build web apps faster without compromising on customizability, flexibility, or performance.
Reflex provides AI Builder for describing apps in natural language, Agent Toolkit with MCP and Skills for AI coding assistants, and Python-native development that integrates seamlessly with AI models and LLMs. Users can build production-ready AI apps entirely in Python without context switching.
Reflex enables one-click deployment to AWS, GCP, Azure, or bare metal with a single command. Teams build once and deploy wherever business needs dictate, with integrated monitoring, versioning, and team management through Reflex Cloud.
Reflex enables teams to write entire applications in Python, eliminating the need for JavaScript/React expertise. Users build UI, backend logic, and deployment in one language, reducing hiring costs and development time by 4-10x compared to traditional React+FastAPI stacks.
Reflex offers SOC 2 certification, HIPAA-compliant deployments, on-premises and VPC deployment options, role-based access control, and integration with company data sources (Postgres, Databricks, private PyPI). Teams can ship secure internal tools without vendor lock-in or rebuilding security infrastructure.
Reflex works with company internal Python packages, private PyPI registries, Postgres, Databricks, Snowflake, and any Python SDK or API. Users leverage existing data infrastructure and tools without rebuilding integrations or data pipelines.
