FastAPI is a Python framework designed to facilitate the creation of APIs, leveraging OpenAPI and JSON Schema to enhance development speed, feature deployment, and bug reduction while improving the overall developer experience. Initiated by Sebastian (tiangolo) in 2018, it has gained significant traction, accumulating over 62,000 stars and more than 5,000 forks on GitHub, with prominent companies like Microsoft, Netflix, and Cisco among its users. The sponsoring entity is a Gold Sponsor of FastAPI, driven by their appreciation for projects utilizing OpenAPI and their limited expertise in Python, making contributions beyond documentation challenging. The sponsor highlights FastAPI's features, including automatic API contract generation based on Python code, and emphasizes their offering, Bump.sh, which enhances documentation with features like a fully hosted, SEO-friendly portal, automated change detection, and access management, positioning it as an improvement over tools like Swagger UI and Redoc.
