How do you maintain a Python package downloaded more than 40 million times every month, while working on it in your free time?

In this episode of Behind the Commit, Mia talks with Daniel Moran, the solo maintainer of FakeRedis, a pure-Python Redis-compatible implementation used for testing, compatibility checks, and server-agnostic development.

Daniel shares how FakeRedis grew from a personal solution into a widely used open-source project supporting Redis, Valkey, and Dragonfly. They also discuss maintaining a 73-variation CI matrix, AI-generated pull requests, avoiding burnout, monetizing a JetBrains GitHub Actions plugin, Django Commons, and his vision for FakeRedis becoming a standard in the ecosystem.
