Coding harness usage signals
Explore public activity across eight source views, by source or by harness. Each keeps its own unit, time window, coverage, and limitations, so adoption context never becomes a quality score.
Source-separated rankings
Most used on OpenRouter
Traffic attributed to public coding apps using OpenRouter's app-attribution mechanism.

Why these sources stay separate
OpenRouter tokens, Homebrew install events, package downloads, editor installs, and repository activity observe different populations. Adding them together would create a precise-looking but invalid total.
- Routing
- OpenRouter attributed tokens and requests over completed 1-day, 7-day, and 30-day UTC windows.
- Distribution
- Homebrew 30d events, npm last-month downloads, and cumulative downloads of explicitly matched stable GitHub release assets.
- Editor marketplaces
- Cumulative VS Code installs, Open VSX downloads, and JetBrains downloads for exact mapped extensions or plugins.
- Repository interest
- GitHub stars and forks for the repository already audited by HarnessMatch, with full, client, or support scope preserved.
