Floci

Any cloud. Locally.

Light, fluffy, and always free. Local cloud emulators for AWS, Azure, GCP, and OCI.

Floci is a family of fast, free, open-source local cloud emulators built with Quarkus Native, with one container per cloud, one port each, no auth tokens, no feature gates, no telemetry. Around the emulators sits a consistent set of client libraries, tooling, and validation so the whole suite feels like one project.

Named after cirrocumulus floccus, the cloud formation that looks like popcorn. 🍿

Every emulated service is available to every user, always: no auth tokens, no paid unlocks, no "community edition" sunset. The emulators are MIT-licensed and stay that way. Fork them, embed them, ship them.

Floci is independent open source, funded by the people and companies who use it. Sponsorship buys gratitude and nothing else: every emulated service is free for everyone, forever, and no sponsor gets features, priority, or roadmap influence that the rest of the Flock does not.
