Coding agents write cloud code faster than ever, but they can't safely run it against a real account. Point them at Floci instead: a local cloud to build, run, and verify against. Instant, free, and credential-free.

Agents connect with throwaway keys. No real cloud secrets in the agent's context or sandbox. Nothing to exfiltrate, nothing to bill.

24 ms cold start, 13 MiB idle. Agents spin up, test, and tear down inside the edit loop instead of waiting on round-trips to a remote account.

Lambda, RDS, Redis, and Kafka run for real, so code an agent verifies locally behaves the same in production. No mock-shaped false positives.

Let agents iterate aggressively. Worst case, they reset a local container, not your staging environment or your cloud bill.

Works with every SDK, CLI, Terraform/OpenTofu module, and test runner your agents already use, with no special integration.

Manage and explore every Floci emulator from a unified CLI or visual dashboard.

A unified command-line interface to start, stop, and inspect all Floci emulators. One install covers AWS, Azure, GCP, and OCI from a single tool.

A visual dashboard for all Floci cloud emulators. Browse resources, inspect data, and manage services across AWS, Azure, GCP, and OCI from one place.

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

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

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.

Compiled with GraalVM Mandrel. Starts in 24ms, idles at 13 MiB, fast enough for inner-loop iteration. Your CI, your laptop, and your AI agents will all thank you.

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

From the inner loop to CI to the classroom — anywhere a real cloud account is too slow, too risky, or too expensive.

Spin up the full stack inside every pipeline job. 24 ms startup adds nothing to the build, each job gets an isolated cloud, and teardown is free.

Build against S3, Pub/Sub, or Service Bus on your laptop — offline if you want. No shared dev account to trip over, no credentials to rotate.

Apply Terraform, OpenTofu, or CloudFormation against localhost first. Catch typos, drift, and bad refactors before they ever touch a real account.

Teach cloud services with zero billing risk. Every student runs the whole stack on their own machine — no accounts to provision, nothing to clean up.

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