Coding harness usage signals
Compare public signals from five ecosystems. Each view keeps its own unit, time window, coverage, and limitations, so you can inspect adoption context without confusing it with quality.
Source-separated rankings
OpenRouter attributed traffic
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 install events, npm last-month downloads, and cumulative VS Code Marketplace installs for exact mapped artifacts.
- Repository interest
- GitHub stars and forks for the repository already audited by HarnessMatch, with full, client, or support scope preserved.
