Floci

Light, fluffy, and always free

---

Floci is a fast, free, and open-source local AWS service emulator built for developers who need reliable AWS services in development and CI without cost, complexity, or vendor lock-in.

Supported Services

See the Services Overview for the full list of emulated services, per-service operation counts, endpoints, and protocol details.

Why Floci?

No account required. No auth tokens, no sign-ups, no telemetry. Pull the image and start building.

No feature gates. Every feature is available to everyone — no community-edition restrictions.

No CI restrictions. Run in your CI pipeline with zero limitations. No credits, no quotas, no paid tiers.

Truly open source. MIT licensed. Fork it, extend it, embed it. No "community edition" sunset coming.
