San Francisco Python-only full-stack web framework eliminating JavaScript requirement; YC W23 $3.3M revenue with open-source foundation competing with Streamlit and Dash for Python developer web application building.
Reflex is a San Francisco-based open-source web application framework enabling Python developers to build full-stack web applications entirely in Python — without writing any JavaScript or CSS — with an architecture that compiles Python to reactive frontend components and handles state management automatically. Founded in 2023 and backed by Y Combinator (W23) with $3.3 million in revenue as of June 2024 and a 22-person team, Reflex's open-source framework has grown rapidly in the Python developer community as developers seek web development alternatives that leverage Python expertise rather than requiring frontend JavaScript proficiency.
Durable execution platform with $1.5B valuation; resilient distributed workflows surviving failures for companies like DoorDash and Netflix, becoming key AI agent orchestration infrastructure.

Founded in 2019 by Maxim Fateev and Samar Abbas (who previously built Cadence workflow at Uber) and having raised over $200 million at a $1.5 billion valuation, Temporal has become the preferred durable execution platform for infrastructure engineers building complex distributed systems.
