Metrics that live with your code
Every commit pushes a sample. Coverage Tracker stores the history and renders the trend, so regressions are visible the moment they land — not at release.
Status badges
Generate shields.io endpoint badges for any metric. Drop the Markdown into your README and the number stays current.
Self-hosted
Runs on Cloudflare Workers from your own account. Your coverage data never leaves your infrastructure.
GitHub-native
Install the GitHub App, grant repo access, and Coverage Tracker picks up owners, repos, default branches and avatars automatically.
One-step ingest
Add the reporting Action to your workflow. It auto-detects Go, Python, and JavaScript coverage reports, collects complexity and duplication, then posts everything with a GitHub Actions OIDC token — no static secret.
Six editor themes
Catppuccin, Gruvbox, Nord, Solarized, Dracula, Tokyo Night — light and dark. The dashboard looks like the editor you already use.

Three steps to live coverage
Deploy the Worker and D1 database to your Cloudflare account once — then adding any repo to coverage tracking takes three steps.
01
Install the GitHub App
Grant access to the repos you want to track. Coverage Tracker registers each project and its default branch automatically.
02
Add the reporting Action
Drop the reporting Action into your workflow. It reads Go, Python, or JavaScript coverage artifacts, collects complexity and duplication, and posts everything to your Worker with a GitHub Actions OIDC token — no static secret required.
03
Watch the trend
Open the dashboard for a per-metric, per-branch trend chart, then generate a status badge for your README.
// make it yours
It looks like your editor
The whole UI re-themes from a single token swap — this entire page included. Pick a colorscheme and watch the charts, badges and surfaces follow.
