This is a browser-based JS benchmarking tool I've been working on for the past weeks, unsatisfied with the alternatives that are out there. The goal is / was supporting most features one would need (like NPM or JSR packages), setup and teardown code, seamless support for async code, etc. and at the same time present a report with not just raw speed (as most tools do) but with useful statistics.

The project is split into two parts, one which is this ready-to-use web UI (obviously, useful for testing in the browser), but also a minimal library that can orchestrate the tests and produce a report (with some nice CLI-based reporters too).
