What is SourceTreeLauncher.exe?
SourceTreeLauncher.exe is the bootstrapper for Atlassian SourceTree. It initializes the SourceTree application, manages updates and ancillary tasks, and then launches the main SourceTree GUI along with its embedded Git operations.
The launcher coordinates starting SourceTree, handling authentication hooks, update checks, and task orchestration. It spawns SourceTree.exe and underlying git processes while keeping a light presence.
Quick Fact: SourceTree Launcher helps streamline startup by delegating heavy work to the main SourceTree process and git operations.
Types of SourceTree Processes
- Launcher Process: SourceTreeLauncher.exe - Bootstrapper
- Main GUI Process: SourceTree.exe - UI and git orchestration
- Git Process: Underlying git operations spawned by SourceTree
- Background Tasks: Update checks, telemetry, and repository indexing
- Helper Utilities: Background helpers for authentication and hooks
- Plugin/Extension Process: Extensions integrated within SourceTree (if any)
