Floci

GitHub, May 14, 2026

If you always wanted to use Amazon Web Services (AWS) but didn't want to pay Amazon money, this is the tool for you: Floci, "A free, open-source local AWS emulator. No account. No feature gates." Now to be clear, I haven't tried to set this up, much less try to make it work in any serious way (and tbh I use Amazon pretty minimally as well - just S3 to store files and SES to send this newsletter by email). "Floci runs real Docker containers for services where in-process emulation would compromise fidelity - stateful databases, connection-heavy protocols, and runtimes that require native execution. The result is wire-compatible behavior against the actual engine, not a simplified approximation."
