Sites detected running c15t by Wappalyzer (Jun 2026). Undercounts: only detects sites Wappalyzer crawls.
c15t is fetched exactly once per install, whichever entry point is used. Includes CI re-installs, bots, and cache misses.
@c15t/cli is run by humans setting up or configuring a project. The closest signal to active developer adoption.
@c15t/dev-tools is added by developers actively building with c15t, not pulled in automatically.
@c15t/iab is advertising-compliance tooling. Teams installing it are running ads, a commercial-intent signal.
Upper bound for self-hosting: @c15t/backend is also pulled in by the CLI and was bundled by legacy versions, so it overstates self-hosting.
Real-world deployments sit somewhere between the ~2.8K sites Wappalyzer can see and the fetch counts above. A single active project generates tens of fetches a month through CI and caching, so ~486.8K core fetches squares with thousands of live deployments, not hundreds of thousands.

YoY multiples compare against a near-zero 2025 base, so they shrink as the project matures. MoM and the shrinking milestone gaps are the better read of current pace.

npm counts tarball downloads, not installs: installing @c15t/nextjs also downloads @c15t/react and c15t, so summed totals count one install several times. Headline numbers on this page only sum the direct-install group; share is each package's slice of that group's last 30 days. The c15t row is the cleanest install proxy.
