loadr

loadr とは？

One prompt. While Claude Fable 5 was briefly available, we asked it to build a load tester in Rust that combined the best of k6, JMeter, Gatling and Locust — plugins, embedded scripting, distributed execution. It returned a real foundation, not a toy. We kept building. Today it's one Rust binary with declarative YAML + JavaScript tests, exact percentiles (HDR histograms — p99.9 is real, not sampled), installable protocol/datastore plugins, a live web UI, distributed agent runs and a CI gate.
