Galactic is an open-source workflow orchestration tool specifically designed to solve the file-conflict problem when running multiple autonomous AI coding agents in parallel on the same project.
Normally, when a developer unleashes two or more AI agents on a single repository simultaneously, the agents overwrite each other's files, crash the local server, and corrupt the Git history. Galactic prevents this by acting as an isolation layer—spinning up each individual agent in its own isolated Git worktree with auto-assigned server ports.
Why It Matters
As agentic coding becomes standard practice, developers are shifting from sequentially prompting a single agent to acting as "managers" orchestrating teams of parallel AI workers. However, local file system constraints have bottlenecked this multi-agent scaling. Galactic unlocks genuinely parallel, conflict-free AI development, massively multiplying a developer's daily throughput without risking repository corruption.
How It Works
When you trigger multiple tasks via Galactic, it creates temporary Git worktrees linked to your main repository but physically isolated in separate directories. It provisions unique port numbers for any local servers the agents need to spin up to test their code. The agents operate independently in these safe sandboxes. Once their tasks are complete and verified, the developer can review the isolated commits and merge them safely back into the primary branch.
Example
A developer is using the Claude Code CLI and wants to implement a new database schema while simultaneously overhauling the frontend CSS. Instead of waiting 10 minutes for one task to finish before starting the next, they use Galactic to dispatch both commands simultaneously. Galactic isolates "Agent A" in worktree-1 (handling SQL) and "Agent B" in worktree-2 (handling CSS). Both agents test their code without port conflicts, allowing the developer to accomplish 20 minutes of autonomous work in just 10 minutes.
