🚀 What I'm building · Floci
Any cloud, locally. Real infrastructure, not mocks.
Floci runs the real thing on your machine: Linux containers for EC2, k3s for EKS and OKE, Redpanda for MSK, actual PostgreSQL and MySQL for RDS. Each emulator ships as a GraalVM native binary that starts in ~24 ms and idles at ~13 MiB of RAM. No accounts, no auth tokens, no feature gates, no telemetry. MIT licensed and free forever.
| Emulator | Cloud | Port | Highlights |
|---|---|---|---|
| 🟠 floci | AWS | 4566 |

Floci is free, MIT licensed and built in the open, and it stays that way: no paywalls, no gated services, no telemetry. It is independent and bootstrapped, not venture-backed. If it has saved you or your team time or cloud spend, sponsorship pays for infrastructure, development time and new emulated services.
Back the Floci project directly, or support me personally. Thank you for keeping open source sustainable.
