Boilerplate
Descriptions you can paste
One line
GitComet is a fast, open source Git GUI written in Rust for Linux, macOS and Windows.
One paragraph
GitComet is an open source desktop Git client built in Rust for Linux, macOS and Windows. It reads repositories directly with gitoxide and renders through the GPU, so it stays responsive on codebases where other clients stall — it opens the Chromium repository in about a second. It covers the full Git surface, including line-level staging, an assisted three-way merge tool, interactive rebase, blame, worktrees and submodules, and it doubles as a drop-in git mergetool and git difftool. Everything stays on the user's machine; there is no account and nothing is uploaded.
Company
GitComet is developed by AutoExplore Oy, a Finnish company building tools that help software teams deliver high-quality software faster.

The mark works on light and dark backgrounds as supplied. Please do not stretch it, recolour it, or set it on a background that reduces its contrast. "GitComet" is one word with a capital G and a capital C.
Benchmark
The numbers, and how they were produced
If you cite these, please cite the method with them. Each client was pointed at the same local clone of the Chromium repository on the same machine and timed from launch until history could be browsed. Peak memory was recorded over the same window.

Things worth saying in a fair review
It is early software
GitComet is 0.1.x. It moves fast, and the interface changes between releases.
No pull request review
There is no GitHub or GitLab API integration. It cannot open, review or merge a pull request.
No Git LFS
Repositories that depend on LFS are not currently served.
