Floci is a free, open-source AWS cloud emulator built with Quarkus and GraalVM native compilation that can run 35 AWS services locally in under 25 milliseconds using only 13MB of memory via a single Docker command. Created after LocalStack dropped its open-source community edition, Floci offers a lightweight alternative for local cloud development and testing. The podcast covers how it was built, GraalVM challenges with third-party libraries, AI-assisted service integration, data persistence, compatibility testing against real AWS APIs, and future plans for Azure and GCP support.
