Git Repository Manager

Merathon

"Your code is a marathon."

The desktop Git client for Linux and Windows: graph, commits, branches and pull requests in a single window.

The promise

A Git client made to stay open all day

Fast

Native Git engine in Rust: the interface stays smooth during a fetch or a rebase.

Safe

Tokens stay in the system keyring. No hook runs when a repository opens.

Light

A .deb package of about 8 MB and little memory at rest.

Complete

From line-by-line commits to pull request review, with GitHub and GitLab.

Interface tour

The whole repository in a single window

Reorder

Drag and drop, or arrow keys.

Can be canceled at any time: back to exactly the initial state.

Sync and notifications

Always up to date, and told when things move

5 min

between two automatic syncs. The sync button, next to the branch name, runs one on demand.

site-vitrineapi-courses: PRs with something newdocs

3 new comments on PR #12

A badge on the icon counts PRs with something new, and a dot marks the tab of the repository concerned.

Pull requests and merge requests

Create, review and merge without leaving the application.

GitHub, GitLab.com and self-hosted GitLab, from the same panel.

Pull requests · from creation to merge

Three steps, one window

1 · Create

Right-click a branch

Target, reviewers, labels, draft. Description pre-filled with the repository's template.

2 · Review

Line-by-line diff

Line comments, search, CI. A commit replies to the threads it addresses.

3 · Merge

Merge, squash or rebase

Behind the target, rebase, safe force push.

Worktrees

Several branches open, with no stash or second clone

A single repository

Commits, branches, tags and stashes shared

New commit visible everywhere, with no push

feature/newsletter

Your work in progress stays here.

hotfix/login

The urgent fix, alongside.

One folder, one tab

Each worktree opens in its own tab, with its files and branch.

Protected branch

Checked out elsewhere, it cannot be deleted, and its menu leads to its worktree.

On deletion, the folder goes and the branch stays.

Git profiles and SSH

Work and personal kept apart, folder by folder

~/dev/pro

Email camille@atelier.example

Account GitLab.com

SSH key id_ed25519_pro

Email camille@client.example

Account Self-hosted GitLab

~/dev/perso

Email camille@perso.example

Account GitHub

The native includeIf rule: command-line git follows the profiles too. An alert flags a repository that would sign with a different email.

Accounts and security

Your tokens never leave the keyring

Diagram: the interface has no access to any token. The Rust backend reads the token from the system keyring, then sends it over HTTPS to GitHub or GitLab.

Package size

Merathon · about 8 MB

Electron application

An Electron application often exceeds 80 MB.
