Run 35 AWS Services Locally FREE: Floci, Quarkus and GraalVM-Powered, LocalStack Alternative (#96)
Shownotes
What if you could run 35 AWS services locally in under 25 milliseconds, using just 13 megabytes of memory, with a single Docker command and no cloud bill? That's exactly what Floci does.
In this episode, Frank Delporte talks with Hector Ventura, the creator of Floci, a free and open-source cloud emulator built with Quarkus and GraalVM native compilation. Hector walks us through why he built it when LocalStack dropped its open-source community edition, how AI tooling helped him accelerate development of new service integrations, the challenges of keeping GraalVM happy with third-party libraries, and the road ahead for Azure and GCP support.
If you're a developer who wants fast local testing, a DevOps engineer writing Terraform, or a student learning cloud without the cost, Floci is worth a look!
