Sourcetree got a lot of us through a lot of years.

It is free, it is Atlassian’s, and for a Bitbucket and Jira shop it fits the way a first-party tool fits. Most people reading this page are not looking for reasons to dislike it. They have hit its ceiling on a large repository and want to know what is next. GitAegis captures a full recovery capsule before a risky operation, and refuses to run the operation if that capsule can’t be taken.

Credit where it's due

Sourcetree has been the on-ramp to Git for an enormous number of developers, and several of its choices remain good ones. It is free, including for commercial work, not a trial, not a public-repositories-only tier. Its Atlassian integration is first-party. Git Flow is built in. And it covers the fundamentals in an interface a beginner can navigate on day one.

One correction worth making before anything else: Sourcetree’s performance reputation is not an Electron problem. It is a natively built application on both platforms. The problem is elsewhere.

If Sourcetree works on your repositories and your budget is zero, keep it. There is no argument here against a tool that is doing its job.

Where Sourcetree is the better choice

  • Free, including for commercial work. Not a trial, and not a public-repositories-only tier.
  • First-party Atlassian integration: Bitbucket Cloud, Bitbucket Data Center and Jira, handled the way a first-party tool handles them. GitAegis does not have it.
  • Git Flow is built in, so a team running that model does not have to remember the command sequence.
  • Coverage of the fundamentals (staging by hunk and line, branches, tags, remotes, stashes, submodules, LFS, interactive rebase and custom actions) in an interface a beginner can navigate on day one.
  • It drives external diff and merge tools. GitAegis never launches one, in any mode, so a resolution workflow built on Beyond Compare or KDiff3 is a real thing you would give up.
  • It ships GitHub, GitLab and Azure DevOps remotes too, so it was never Bitbucket-only.

Where people actually hit the ceiling

Two complaints dominate reviews and both are fair. The third is the one people only notice on the day it costs them.

The ceiling

Performance and stability on large repositories. Long refresh cycles, an interface that stops responding on a deep history or a wide working tree, and states where the only fix is a restart. Teams on monorepos tend to be the ones who leave.

Pace of development. Sourcetree is maintained rather than actively expanded. For a free tool that is an entirely reasonable position for Atlassian to take, and it also means the ceiling you hit today is likely to be the ceiling next year.

When something goes wrong, it does not help you get the work back. No snapshot before the operation, no per-domain restore, no timeline of what happened to the repository, no damage scan. Recovery is you, a terminal, and git reflog.

What GitAegis does instead

The capsule is written before the command runs. Six domains (refs, index, staged changes, working changes, untracked files, operation state) on disk before the first git invocation. If it can’t be written the operation is blocked, and no control in the interface waives that.

Restore is per domain. Refs only, working tree only, untracked files only, or all of it.

The Flight Recorder records what GitAegis didn’t cause. A filesystem watcher means ref, HEAD, index and stash changes from your terminal or your editor land on the same timeline, with state hashes you can roll back to. File-content edits are not timeline events; they surface in status.

Lost Work searches beyond the reflog: the stash reflog, Flight Recorder “before” oids, refs/aegis/ recovery refs, capsule bundles, sibling worktree HEADs and a bounded git fsck --unreachable --dangling, then offers to put a branch back on what it finds.

Doctor and Safe Mode. Doctor scans for real damage, shows the evidence, and proposes repairs that take a capsule first, with core.hooksPath=/dev/null pinned on the Git it spawns. Safe Mode locks mutating controls when the index or HEAD can’t be trusted.

git gc, git prune and git reflog expire are not implemented at all.

Side by side

Six rows go to Sourcetree. Three of them (external diff and merge tools, Git Flow, and Atlassian integration) are things GitAegis deliberately does not do. The other three are gaps, and they are labelled as gaps.

1 GitAegis captures the merge, cherry-pick and revert markers and puts them back on restore. A rebase in progress is recorded as present rather than captured, and it is not replayed.

2 The Flight Recorder records ref, HEAD, index, stash and worktree-registration changes made outside the client. It does not turn edits to file contents into timeline events.

3 A dash means Sourcetree publishes no commitment either way, not that Sourcetree runs those commands.

4 Sourcetree resolves conflicts primarily by handing off to an external diff and merge tool, which is why those two rows read the way they do. GitAegis never launches an external diff or merge tool, in any mode.

5 Sourcetree is natively built on both platforms. Its reputation for slowness on large repositories is not an Electron problem.

6 GitAegis ships for macOS. There is no Windows or Linux build to download.

7 GitAegis does not connect to a hosting provider from the client today. You can clone, fetch, pull and push GitHub, GitLab and Bitbucket remotes as ordinary Git remotes; what you do not get is pull requests, CI status and reviews inside GitAegis.

8 Sourcetree on Windows prompts for an Atlassian account at first run; on macOS it does not. The GitAegis macOS edition has no sign-in at all.

A procedure, not an explainer

Migrating from Sourcetree

Nothing here touches your repositories. Both clients execute Git against the standard on-disk format, so this is a change of interface, not a conversion.

  1. Check your Git version.

    GitAegis requires Git 2.38.0or newer, already installed, and never bundles or downloads it. On macOS 12, Apple’s Command Line Tools ship Git 2.37.1 (below the floor) so install Git with Homebrew first. Sourcetree could use a bundled Git, which is why this is the step people miss.

  2. Add your repositories.

    GitAegis discovers repositories across a folder tree, so point it at the directory your clones live in and it will find them, rather than making you re-add each bookmark by hand.

  3. Credentials and keys carry over.

    GitAegis uses your system keychain and your own SSH keys, so nothing needs re-authorising at the OS level. Subprocesses pin GIT_TERMINAL_PROMPT=0, so a misconfigured remote fails visibly instead of hanging on an invisible password prompt.

  4. If Bitbucket or Jira is central to your work, stop here.

    Stay on Sourcetree if this describes you.

    GitAegis does not integrate with Bitbucket or Jira, and today it does not integrate with GitHub or GitLab from the client either. There are no pull requests, no merge requests, no reviews and no CI status inside GitAegis, for any host.

    Your remotes still work. Clone, fetch, pull and push over HTTPS or SSH behave exactly as they do anywhere else, with your own credentials. What you lose is the review workflow inside the client, and if that is where your day happens, this is the wrong switch to make.

  5. Replace your custom actions with the command palette.

    ⌘K runs real intents rather than a list of menu labels. It is not a scripting host: Sourcetree’s custom actions have no direct equivalent, and a script you ran from Sourcetree stays in your terminal.

  6. Expect the diff and merge experience to differ.

    GitAegis does not launch external diff or merge tools, in any mode. If your resolution workflow depends on Beyond Compare, KDiff3 or similar, that is a genuine change in how you will work: test it before you commit to the switch, which costs nothing because the macOS edition is free and has no time limit.

  7. Learn one new habit.

    Destructive operations open the Operation Preview drawer: intent, risk level, preconditions, the exact commands, the checkpoint, and the rollback plan. It takes a few seconds longer than a confirmation dialog, and it is the reason the operation is reversible.

When staying on Sourcetree is right

Stay if

  • Your organisation runs on Bitbucket and Jira, and in-client integration matters.
  • You need pull requests, reviews or CI status in the client at all. GitAegis has none of that for any host today.
  • Your repositories are modest and Sourcetree is not making you wait.
  • Your merge workflow depends on an external diff and merge tool.
  • Your team runs Git Flow and uses Sourcetree’s built-in support for it.
  • You work on Windows. There is no GitAegis build for it.

Move to GitAegis if

  • Sourcetree stalls on the repository you actually work in.
  • You have lost work, and reconstructing it from the reflog is now a recurring cost.
  • You want a snapshot taken before the operation, and the operation refused without one.
  • You want a damage scan that shows its evidence before it proposes a repair, and a mode that locks the controls when the index can’t be trusted.
  • You are on macOS, and the price you want to pay is nothing and no account.

Moving costs nothing to try. GitAegis for macOS is free, does not require an account, and includes the whole local product: full Git, Operation Preview on every destructive operation, recovery capsules, Doctor’s scan and its repairs, Safe Mode, the Flight Recorder and Lost Work. You can run it alongside Sourcetree on the same repositories at the same time; neither changes the on-disk format.
