Open source

Open source we sponsor

Svix is built on open source. We sponsor projects that helped us get here, so the people who maintain them can keep doing it.

FastAPI

Python web framework

A high-performance Python framework for building APIs with standard type hints, created by Sebastián Ramírez.

At Svix

The first version of the Svix API was built on FastAPI, and it handled our customers' API calls for years.

Rust storage engine

A log-structured, embeddable key-value storage engine written in Rust.

At Svix

Fjall is the storage layer of Diom, our open source platform for caching, rate limiting, idempotency, and queues.

If there's a project that you think we should sponsor, please contact us and we'll evaluate it.

The Svix webhook server is MIT licensed, and we maintain Standard Webhooks and Diom in the open too.
