Download GitChrono for desktop

v0.2.1 — early, unsigned pre-release. Also available: Windows .msi

A free, no-account, ~3 MB native git GUI — see how it compares to GitKraken, Sourcetree & GitHub Desktop →

macOS (Apple Silicon) macOS (Intel) Windows (.exe) Linux (.deb) Linux (.AppImage)

Unsigned early build (no Apple/Windows developer account behind this yet). macOS will claim the app "is damaged" — it isn't; that's how recent macOS reports any unsigned download. Fix: drag GitChrono to Applications, then run xattr -cr /Applications/GitChrono.app in Terminal once, and open normally. Windows: on the SmartScreen prompt, click More info → Run anyway. No account, no network, no credentials — GitChrono only reads/writes local git repos.

How it works

GitChrono calls the public GitHub REST API directly from your browser — there is no server in the middle, no account, and no token. It reads the most recent commits you select (100–300), then charts commit activity over time, ranks contributors, and shows the repository's language makeup.

Anonymous GitHub API access is limited to 60 requests per hour per IP address, so GitChrono analyses a recent window rather than a repository's entire history. Nothing you enter leaves your browser except the repository name, sent to GitHub to fetch its public data. Private repositories are not supported in this version.

Add it to your own site

Writing about an open-source project? You can embed a live commit-activity visualization of any public repo in one line of HTML — a self-contained Web Component, no iframe and no build step:

<script src="https://gitchrono.x1.kumavolt.dev/widget.js" async></script>
<gitchrono-widget repo="facebook/react"></gitchrono-widget>

See the embedding guide for options and a live demo.
