Treehouse – isolate multple dev environments on different Git worktrees

Treehouse, a new open-source CLI tool published on GitHub, addresses the challenge of managing multiple development environments tied to different Git worktrees. It assigns a stable, unique number to each worktree, which developers can use to derive per-worktree local configuration such as ports, database names, or any other environment-specific settings. This eliminates the need for manual environment switching or complex configuration management when working on multiple branches concurrently. By leveraging Git worktrees—a feature that allows checking out multiple branches in separate directories—Treehouse ensures that each worktree gets its own isolated environment, reducing conflicts and setup time. The tool is designed for developers who frequently switch between features, bug fixes, or experiments, providing a systematic way to keep environments separate without additional overhead. The project is hosted on GitHub under the stemps organization, and its simplicity suggests it can be integrated into existing workflows with minimal friction. While the excerpt does not specify installation methods or dependencies, the concept directly addresses a common pain point in modern development practices where parallel work on multiple branches is routine.
