Stats

c15t Growth

Real npm and GitHub numbers. Complete months only. No projections, no partial data.

Sourced live from api.npmjs.org and the GitHub API. Refreshes hourly, so you can verify the numbers yourself. Installs are downloads of the c15t package. Every v2 install fetches it once, whichever framework package it starts from, and in v3 it is the package you install.

Adoption Signals

Napkin math, caveats included

v3 share of installs, 7 days6.1%

14.5K v3 and 224.2K v2 installs. 6.7K v3 installs skipped the c15t umbrella, so the install charts miss them.

Installs on c15t 3.1, 7 days0.6%

c15t 3.1 was released 2 days ago. The share of installs already on it shows how quickly projects upgrade; a new release starts near zero.

CLI fetches, 30 days39K

@c15t/cli is run by people setting up, configuring, or migrating a project, and nothing installs it automatically. The closest signal to active developer adoption.

Dev-tools fetches, 30 days54.9K

@c15t/dev-tools is added by developers actively building with c15t. v3 React installs pull it in automatically, so this stops meaning intent as v3 grows.

IAB TCF fetches, 30 days25.7K

@c15t/iab is advertising-compliance tooling, a commercial-intent signal from teams running ads. v3 React installs pull it in automatically.

Backend downloads, 30 days363.9K

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.

Fetches are not deployments: a single active project generates tens of fetches a month through CI and caching, so ~1.1M installs a month means far fewer live projects.

CLI Runs per Week

Last 12 complete weeks

CLI runs are @c15t/cli downloads. People run it to set up, configure, or migrate a project, and no package installs it automatically, so it tracks developers rather than CI. If installs grow faster than CLI runs, growth is coming from existing projects. Migration codemods also run through the CLI, so a major release brings a spike that is not new projects.

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.

Downloads by Package

All published packages

npm counts tarball downloads, dependencies included: installing @c15t/nextjs also downloads @c15t/react and c15t, so adding packages up counts one install several times. Install numbers on this page use the c15t row alone, which every install fetches once. Vs c15t installs compares each package's last 30 days with c15t's; above 100% means it is also fetched outside client installs, such as by the CLI or a self-hosted backend.
