GitComet vs GitKraken
The best-known cross-platform Git GUI. Where the two differ on speed, licensing and what the free tier covers.
Compare
GitComet next to the other Git clients
Most Git GUI comparisons are feature checklists. This one starts with a measurement, because the thing that makes a Git client unusable is rarely a missing feature — it is waiting.
Measured
Opening the Chromium repository
Chromium is the test because it is the case that broke every client we tried: roughly 25 GB of working tree and well over a million commits. Each client was pointed at the same clone on the same machine and timed until the history was browsable.
| Client | Version | Time to open | Memory |
|---|---|---|---|
| GitComet | v0.1.6 | 1s | 265MB |
| GitFiend | v0.45.3 | 1s | 289MB |
| SourceGit | v2026.6 | 3.5s | 301MB |
| SmartGit | v25.1.110 | 18s | 4.8GB |
| GitKraken | v11.10.0 | 25s | 2GB |
| Megit | v0.10.0 | 29s | 14.4GB |
| Gittyup | v2.0.0 | 43s | 2.5GB + 1.5GB indexer |
| gitg | v44 | crashed | crashed |
| ungit | v1.5.30 | crashed | crashed |
| guitar | v1.3.1-1 | crashed | crashed |
Three clients — gitg, ungit and guitar — did not finish; they are listed as crashed rather than given a number. These figures are a snapshot at the versions shown, taken 2026-04. Later releases of any client may perform differently, and you should re-run the test on your own repository before taking anyone's word for it, including ours.
Side by side
Compared to a specific client
GitComet vs Sourcetree
The long-standing free client from Atlassian — and the one that has never had a Linux build.
GitComet vs KDiff3
For the merge tool specifically. GitComet accepts KDiff3's own arguments, so it can replace it without changing your scripts.
Caveats
Where GitComet is the wrong choice
A comparison page that only lists reasons to switch is an advertisement. These are the cases where one of the others is the better tool today.
You want pull requests in the client
GitComet does not browse or review pull requests, and has no GitHub or GitLab API integration. If reviewing PRs without leaving the app matters, GitKraken and Tower do that and GitComet does not.
You depend on Git LFS or submodule-heavy workflows with LFS
GitComet has no Git LFS support. Repositories that lean on it should stay with a client that handles it.
You need a mature, settled product
GitComet is 0.1.x and moves quickly. That means fixes land fast and it also means the interface changes between releases. A team that wants stability above all will be happier elsewhere for now.
