# Atlassian SourceTree Published January 1, 2026 · Updated August 10, 2026 Graphical client for Git version control Category: Developer Tools · Free · Replaces Tower ($69/year) · [Official website](https://www.sourcetreeapp.com/) ## Install with Homebrew `brew install --cask sourcetree` ## Quick take August 2026: Sourcetree is alive, free, Universal Binary, and still the best $0 Bitbucket/Mercurial GUI on Mac, but it is no longer the default power-user pick. Fork and Sublime Merge feel faster; GitKraken is flashier. Keep it for Atlassian depth or Mercurial; otherwise evaluate Fork first. Best for: Bitbucket/Jira teams who want a free GUI, Developers maintaining Mercurial alongside Git, Students and SMEs avoiding Git client subscriptions ## What is Sourcetree? Sourcetree is Atlassian’s free desktop client for Git and Mercurial on macOS and Windows. In August 2026 the Mac build is listed at 4.2.19 on major download mirrors, remains free for personal and commercial use, and still requires an Atlassian account to unlock the app. It shows repositories, branches, and file changes so most day-to-day version-control work can happen without the terminal. First released in 2011, Sourcetree is still maintained, but the 2026 Mac channel is clearly in maintenance mode: release notes emphasise stability, localisation, TLS 1.2+ for Mercurial, and repository-rename fixes rather than a redesigned UI. Native Apple Silicon support has been present since 4.1.6, and the 4.2.x line targets macOS 10.15 or later, so it runs on M-series Macs including systems on macOS Tahoe 26.x. What still sets it apart: a $0 licence, dual Git and Mercurial support, Git LFS, Git-flow, interactive rebase, and Bitbucket/Jira smart-commit hooks. Independent 2026 Git GUI roundups usually recommend Fork or GitKraken for speed and polish, while keeping Sourcetree as the free Atlassian-ecosystem option. Choose it when price, Mercurial, or Bitbucket depth matter; trial Fork first when graph performance is the bottleneck. Installation remains a zip or Homebrew Cask; there is no paid Mac App Store unlock. Once signed in, you can add local repos or clone from the remote account browser. That onboarding path has been stable for years, which is either comforting or stagnant depending on whether you wanted a redesign. ## Features - **Visual commit graph and staging.** Sourcetree’s main view is a commit graph with file, hunk, and line staging plus one-click commit, push, pull, and merge. Through the 4.2.x Mac line culminating in 4.2.19 (August 2026 mirrors), Atlassian has prioritised stability and localisation rather than a redesign, so the familiar visual workflow is still what you get for everyday Git and Mercurial work. Bookmarks let you jump between repos without re-entering paths. The sidebar keeps remotes and branches visible so you spend less time reconstructing state from `git status` alone. - **Git and Mercurial in one client.** Unlike most modern Git-only GUIs, Sourcetree supports both Git and Mercurial. That dual front end matters if you still maintain Mercurial repos alongside Git, or join a team that has not finished migrating. Common clone, commit, branch, and merge actions are available for both systems without switching tools. Switching mental models still takes care: branch names and bookmark concepts differ between systems. The value is one installer and one UI chrome, not identical semantics under the hood. - **Advanced Git operations in the GUI.** Interactive rebase, stash, cherry-pick, and submodule management are available from the interface. That means you can clean history, move specific commits between branches, and work with nested repos without memorising every flag. Errors still happen, but the graph and conflict tools reduce the guesswork that pure command-line work invites for less frequent tasks. Interactive rebase in particular benefits from seeing the commit list before you rewrite. You can still abort and return to the prior HEAD if a rewrite goes wrong, same as on the command line. - **Git-flow and Mercurial Flow helpers.** Sourcetree can drive Git-flow and Mercurial Flow branching models from the UI: create feature, release, and hotfix branches and finish them with the merges those models expect. Teams that already standardised on those patterns get fewer missed steps than doing every branch rename by hand in the terminal. - **Remote hosts and account bookmarks.** You can connect Bitbucket, GitHub, GitLab, and Azure DevOps accounts, search remotes, clone, and keep multiple hosts in one bookmark list. Local and remote branches stay visible so push and pull do not require a separate browser tab for every host. Bitbucket and Jira smart commits remain the strongest Atlassian-specific hooks. OAuth or app-password setups vary by host; expect to create tokens for GitHub and GitLab the same way you would for any desktop Git client. Bitbucket login is simply the least awkward path inside Atlassian shops. - **Visual merge conflict tools.** When merges collide, Sourcetree shows conflicting hunks with side-by-side comparison and line-level choices. You can also hand off to external tools such as FileMerge for harder cases. The goal is simple: finish the conflict without pasting marker soup through a plain text editor unless you prefer that. - **Git Large File Storage (LFS).** Git LFS support is built in for binary-heavy projects: design assets, audio, video, and other large files that should not bloat the core Git object store. Creative and game teams use this so history stays usable while assets still version with the code. - **2026 maintenance releases on Apple Silicon.** Mac 4.2.x updates in 2026 focus on crash fixes, repository renaming, preference-tab localisation, Mercurial TLS hardening, and continued Universal Binary performance on Apple Silicon. That release pattern signals a mature, still-supported product rather than a dead one, even if Fork and Sublime Merge ship UI changes faster. ## How to Install Sourcetree on Mac Install Sourcetree from the official Mac download or Homebrew Cask. You will need an Atlassian account on first launch. 1. **Download from the official site.** Open www.sourcetreeapp.com, choose Download for Mac OS X, accept the Atlassian Customer Agreement, and save the Sourcetree.zip installer. Prefer this channel or Homebrew over third-party mirrors when you can. 2. **Install into Applications.** Open the zip, then drag Sourcetree.app into /Applications. Launch from Launchpad or Spotlight after the copy finishes. 3. **First launch and Atlassian sign-in.** Open Sourcetree. If macOS warns about an internet download, choose Open. Complete the setup wizard, accept licences, and sign in with an Atlassian account when prompted. You can connect Bitbucket later if you only need local repos at first. 4. **Optional: Homebrew Cask.** With Homebrew installed, run `brew install --cask sourcetree`. Update later with `brew upgrade --cask sourcetree`. ## Pros - Completely free for personal and commercial projects with no feature paywall. - Native Apple Silicon Universal Binary with ongoing 4.2.x Mac builds in 2026. - Supports both Git and Mercurial in one client, which is rare among modern GUIs. - Bitbucket account manager and Jira smart commits fit Atlassian-centric teams. - Visual interactive rebase, Git-flow, Git LFS, submodules, and remote search built in. - Works with GitHub, GitLab, Bitbucket, and Azure DevOps remotes from one bookmark list. - Homebrew Cask and official Mac download keep installation simple on Tahoe. - Release notes in 2026 still ship, so you are not installing an abandoned binary. ## Cons - Noticeably slower than Fork on large commit graphs according to 2026 comparisons. - UI and feature velocity lag Fork, GitKraken, and Sublime Merge. - Requires an Atlassian account despite the free licence. - No Linux desktop client for mixed OS engineering teams. - Maintenance-mode UI means accessibility and density improvements arrive slowly compared with Fork. ## Sourcetree on Mac in 2026: what still matters Sourcetree is a free Atlassian desktop client for Git and Mercurial. On Mac it still solves a practical problem: give people a graph, staging area, and remote bookmarks without charging a seat fee. That pitch has not changed much even as Fork, Sublime Merge, and GitKraken raised the bar on speed and polish. August 2026 reality check: download mirrors and TechSpot list Mac 4.2.19 with continued Apple Silicon support. Atlassian has not introduced a paid Sourcetree tier. Competitive pressure comes from Fork’s native speed, Sublime Merge Build 2125’s LFS locking improvements (April 2026), and GitHub Desktop’s simplicity. If your team standardises on Bitbucket Pipelines and Jira issue keys in commit messages, Sourcetree’s smart commits still reduce context switching. If you only push to GitHub and care about interactive rebase fluidity, budget for Fork. On macOS Tahoe, confirm menu-bar and permission prompts after install, keep system Git updated, and avoid relying solely on embedded binaries when large monorepos hit filesystem edge cases. Prefer official downloads or Homebrew Casks, keep a short rollback plan, and evaluate rivals with the same weekly workflow before migrating credentials. Vendor changelogs beat hearsay when deciding whether free still covers your workload. A practical evaluation week looks like this: install 4.2.19 from a trusted channel, open your largest real repo, exercise stage-commit-push, interactive rebase, a conflicted merge, and LFS if you use it. Time how the graph scrolls compared with Fork on the same machine. If Sourcetree stays responsive and Bitbucket hooks save you daily clicks, the free licence is enough. If the graph stutters, leave. Many 2026 roundups describe exactly that fork in the road. Practical Bitbucket note: if your company still documents Sourcetree in onboarding PDFs, confirm the Mac build number against sourcetreeapp.com or Homebrew before training day. Version skew between Windows and Mac is usually small in the 4.2.x line, but localisation and TLS fixes land in point releases that matter for corporate proxies. Keep one known-good DMG or Cask pin in internal software catalogues so a mirror outage does not block new hires. For mixed GitHub and Bitbucket orgs, teach people to bookmark both hosts rather than re-auth every week. None of that is glamorous, but it is how free tools survive inside real companies after the blog posts move on to shinier clients. Mercurial still matters more than Git Twitter admits. A non-trivial set of science, games, and long-lived enterprise codebases never finished a migration, and dual-VCS clients are scarce. Sourcetree’s willingness to keep Mercurial alongside Git is a concrete reason to install it even if you prefer Fork for pure Git work on other machines. When a contractor hands you an hg clone, opening it in the same GUI you already use for Bitbucket Git repos is boring in the best way. Account friction is real: some people resent creating an Atlassian login for a free desktop tool. The requirement is not a paid upsell, but it is still a gate. If your security team already provisions Atlassian accounts for Jira, that cost is zero. If you are a student who only needs GitHub, GitHub Desktop or a short Fork trial may feel cleaner. Be honest about that tradeoff in team standards docs rather than pretending free means zero friction. Performance characteristics reported in 2026 comparisons are consistent: Sourcetree is acceptable on medium repos and slower on huge graphs with dense branch topology. Filters, partial clones, and sparse-checkout strategies help at the Git layer before any GUI can. Do not expect a free Electron-adjacent desktop client from a cloud company to out-render a native indie tool whose entire product is the graph. Measure on your monorepo, not on a sample todo app. Security hygiene is the same as any Git client: keep the app updated through 4.2.x, prefer SSH keys with hardware-backed storage when policy allows, and review which accounts stay signed in on shared Macs. Embedded Git updates close CVEs over time; still patch system Git. Sourcetree does not replace your secret scanning or commit signing policy. It is a viewer and operator for history you already protect elsewhere. Training angle for leads: pair Sourcetree with a one-page cheatsheet that maps GUI buttons to the underlying Git commands. Juniors who only click buttons struggle the first time CI fails on a rebase. The graph is a teaching aid, not a substitute for knowing what rewrite history does to shared branches. Teams that treat the GUI as training wheels plus a daily driver tend to keep both Sourcetree and terminal fluency. ## FAQ ### Is Sourcetree truly free? Yes. Sourcetree remains free for personal and commercial use with no premium desktop tier. You must create or use an Atlassian account to sign in. That account requirement is the main non-price caveat. ### Does Sourcetree support Apple Silicon Macs? Yes. Native Apple Silicon support arrived in 4.1.6 and continues in the 4.2.x Universal Binary line (macOS 10.15+), including Macs on Tahoe 26.x. Prefer the system Git binary on Apple Silicon for best performance. ### Can I use Sourcetree with GitHub, GitLab, or other hosts? Yes. Sourcetree is origin-independent. You can connect GitHub, Bitbucket Cloud, Bitbucket Server, GitLab, and Azure DevOps accounts, then clone, push, pull, and fetch from one window. Multiple host accounts can stay signed in at once. ### Why use Sourcetree instead of the command line? The GUI shows history, branches, and staged hunks without you reconstructing state from terminal output. Beginners learn faster; experienced users still reach for interactive rebase, cherry-pick, and conflict tools when they want a picture of the graph. Hard or scripted work can still drop to a terminal opened from the repo. ### How does Sourcetree behave on large repositories? On very large histories, many branches, or huge untracked trees, Sourcetree can use more CPU and memory and feel slower than Fork. Mitigations: use a current system Git install, filter untracked noise, and rely on Git LFS for big binaries so the core history stays smaller. ### Is Sourcetree suitable for Git beginners? Yes. The branch graph, visual diffs, and one-click common actions lower the first-week barrier. Advanced operations are still available later; you do not need them on day one. ### Can I integrate Sourcetree with Jira or Confluence? Jira smart commits let you put issue keys in commit messages so comments or transitions land on the ticket. Sourcetree is not a full Jira client, and Confluence has no first-class in-app integration. Bitbucket remains the deepest hosting hook. ### How often is Sourcetree updated, and what support exists? Atlassian continues to ship Mac and Windows builds. In August 2026 Mac mirrors list 4.2.19 with stability and TLS fixes. Support runs through the Atlassian Community, knowledge base, and product documentation rather than a rapid consumer changelog. ### Does Sourcetree replace the command line entirely? For most commit, branch, merge, pull, and push work, the GUI is enough. For specialised scripts, deep recovery, or rare plumbing commands, open the terminal Sourcetree can launch in the repo and finish there. ### Should my whole team standardise on Sourcetree in 2026? Only if Bitbucket depth, Mercurial, or a hard $0 requirement dominate. Otherwise let individuals pick Fork, Sublime Merge, or the terminal as long as commit conventions and host auth stay consistent. Standardising the host and review process matters more than standardising the Git GUI. ## Sources - [SourceTree Download Free - 4.2.19 | TechSpot](https://www.techspot.com/downloads/6740-sourcetree.html) - [SourceTree for Mac - FileHorse](https://mac.filehorse.com/download-sourcetree/) - [Sourcetree official site (Mac)](https://www.sourcetreeapp.com/?v=mac) - [Sourcetree Release Notes 4.2.5](https://product-downloads.atlassian.com/software/sourcetree/ReleaseNotes/Sourcetree_4.2.5.html) - [Best Git Clients in 2026 - Brian Detering](https://briandetering.net/2026/06/04/best-git-clients-2026/) - [GitKraken vs Fork vs Tower 2026](https://thesoftwarescout.com/gitkraken-vs-fork-vs-tower-2026-best-mac-git-gui/) - [Git GUI Clients 2026 Comparison](https://tools.aileapers.com/articles/67-git-gui-clients-compared-2026.html) - [Fork vs Sourcetree 2026 - Toolradar](https://toolradar.com/compare/fork-git-vs-sourcetree) ## Related - [Cursor](https://bundl.run/apps/cursor) - [Claude Code](https://bundl.run/apps/claude-code) - [ChatGPT](https://bundl.run/apps/chatgpt) - [Claude](https://bundl.run/apps/claude) - [Codex](https://bundl.run/apps/codex) - [Windsurf](https://bundl.run/apps/windsurf) - [Atlassian SourceTree vs Fork](https://bundl.run/compare/fork-vs-sourcetree) - [Atlassian SourceTree vs GitKraken](https://bundl.run/compare/gitkraken-vs-sourcetree) - [Atlassian SourceTree vs GitHub Desktop](https://bundl.run/compare/github-desktop-vs-sourcetree) - [Free alternative to Tower](https://bundl.run/https:/) ```json { "@context": "https://schema.org", "@graph": [ { "@type": "Organization", "@id": "https://bundl.run/#organization", "name": "Bundl.run", "url": "https://bundl.run", "logo": { "@type": "ImageObject", "url": "https://bundl.run/og-image.png", "width": 1200, "height": 630 }, "description": "The Ninite for Mac.
