Built for developers who ship.

No gatekeeping. No pricing tiers. No surprises. A local cloud that starts in milliseconds and works everywhere.

$0

MIT Licensed. Forever free.

Fork it, embed it, extend it. No "community edition" sunset, no enterprise feature flags. Every service is available to every developer, always.

No auth token. Ever.

Pull the Docker image and go. No sign-ups, no API keys, no telemetry. LocalStack started requiring an auth token in March 2026. Floci never will.

24ms

Native binary speed.

Compiled with GraalVM Mandrel. Starts in 24ms, idles at 13 MiB. Your CI pipeline and your laptop will both thank you.

real

Real engines, not mocks.

Lambda runs in real Docker containers. RDS uses real PostgreSQL/MySQL. ElastiCache runs real Redis. 100% protocol fidelity, no surprises in production.

One install. Every service, locally.

No account, no token. Pick your platform and go.
