Fast and fake. Tiny, instant, until your code touches a real engine and the abstraction cracks. Heavy and faithful. Closer to AWS, but a 3-second startup, hundreds of MB, a bundled Python runtime that turns every CI job into a slow morning. I built Floci to refuse the choice. One principle: Be the lightest thing possible. Be real where it counts. The two halves of every AWS service Read enough AWS API docs and you notice every service has two parts: A control plane: "create this bucket, list my queues." Just CRUD over JSON or XML.
