constellagent
constellagent is an open-source macOS application that provides a unified workspace for running multiple AI coding agents in parallel. Each agent operates in its own isolated environment, featuring a dedicated terminal, integrated code editor, and a separate git worktree to avoid conflicts. This allows developers to assign different coding tasks to multiple agents simultaneously, such as bug fixes, feature implementations, or code reviews, and manage them from a single graphical interface. The app is built with Electron and TypeScript, incorporating a Monaco-based editor and a diff pane for reviewing changes. It aims to boost productivity by enabling true parallel development with AI assistance, while maintaining clean isolation through git worktrees. The interface includes a file tree for navigating code, and the app manages agent sessions, terminal sessions, and git operations seamlessly.

Problem solved
Software developers often need to handle multiple coding tasks concurrently, such as fixing bugs while implementing features, but managing several AI coding agents manually is cumbersome and error-prone. constellagent addresses this by providing a macOS desktop application that runs multiple AI agents simultaneously, each in its own isolated git worktree with a dedicated terminal and editor, preventing cross-task interference and streamlining parallel development workflows.
Use cases
- Running multiple bug fixes in parallel, with each agent working on a separate issue in its own git worktree.
- Assigning one AI agent to implement a new feature while another writes unit tests, both operating in isolated environments.
- Conducting code reviews by spawning several agents to examine different modules or pull requests at the same time.
- Prototyping alternative implementations of a feature by having multiple agents explore different approaches in isolated branches.
- Refactoring a large codebase by dividing refactoring tasks among several agents, each handling a distinct module.
Audience
- Developers
Pros
- Isolated environments prevent task interference using git worktrees.
- Parallel AI agent execution accelerates multi-task development.
- Integrated terminal and editor reduce context switching.
- Graphical diff pane for reviewing agent-made changes before merging.
- Open-source and community-driven, allowing customization and extension.
Cons
- Currently limited to macOS, limiting cross-platform availability.
- Requires users to set up and configure AI coding agents separately.
- Early-stage project with small community and no stable releases yet.
