Progressive web metrics at your fingertipz
A CLI wrapper around Lighthouse that adds multi-run median reporting, Google Sheets submission, and CI expectation assertions for web performance metrics. The README opens with a deprecation notice pointing to Lighthouse CI, which is the honest answer to whether you should use this. Last commit was late 2022.
The expectation/assertion system for CI thresholds (warn vs error levels) was genuinely useful before Lighthouse CI absorbed the pattern. Multi-run median selection by TTI is the right heuristic for noisy perf measurements. Google Drive trace upload + timeline-viewer integration gave you shareable audit URLs before that was built into Lighthouse itself.
Deprecated by its own author — the README says so in the first line. Lighthouse's internal API has changed enough since 2022 that this almost certainly breaks on current Node/Chrome versions. The Google OAuth/Sheets integration requires manually copying a spreadsheet and setting up a Google Developer project, which is significant friction for what amounts to a CSV dump. No replacement is planned; the project is a dead end.
