Fearless API Development.

Foreign keys that seed valid IDs out of the box? Sold.

First mock server my designer could run herself.

Wrote an entire demo backend in YAML on the train to a meetup. Zero servers harmed, fully offline.

Custom error bodies per route saved my integration tests. Finally a mock that fails the way prod does.

Replaced a 200-line Express mock with a 12-line akuma.yml. Code review took thirty seconds, and my frontend team finally stopped waiting on me to hand-write fixtures.

The persistence is the part I didn't know I needed. I seed once, refresh the page a hundred times, and the data is still sitting right where I left it.

Deleted our janky json-server fork. The akuma.yml lives in the repo now, reviews like real code, and diffs cleanly in pull requests. Nobody fights it anymore.

First mock where the config is shorter than the thing it replaces, and it still gives me real tables, real IDs, matched responses, and custom errors. I'm not going back.
