Reflex

Reflex is the operating system for building mission-critical enterprise applications. We're replacing the fragmented enterprise stack with a single, unified platform to build, deploy, and manage production applications end-to-end.

Built on one of the fastest-growing open-source Python frameworks (28,000+ GitHub stars, 35,000+ monthly developers), Reflex empowers teams to own the entire lifecycle of their apps — from idea to production — without needing specialized infrastructure, DevOps, or platform teams. We provide solid, reusable abstractions at both the framework and infrastructure layers. Because we own the underlying open-source framework and the platform it runs on, we can manage the full lifecycle of the application seamlessly.

With Reflex, teams securely connect to company data, use AI to build standardized applications on top of our open-source framework, and deploy with a single click to share across their organization. Our AI Builder generates real, editable code — not fragile black boxes — and can be deployed anywhere, including fully air-gapped on-prem environments.

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 has powered over 1 million applications and is trusted by Amazon, World Bank, Man Group, Dell, UNICEF, and 30% of Fortune 500 companies for mission-critical applications across finance, healthcare, and government.
