Free open-source containerized runtime environments giving each git worktree full isolation so multiple AI coding agents can work in parallel.
Coasts creates fully isolated local development environments (containerized hosts, each with its own ports, network, and services) for each git worktree so multiple AI coding agents can build and test in parallel on a single machine without port collisions or resource conflicts. It works with any agentic coding tool that uses git worktrees—Claude Code, Cursor, Codex—and supports hybrid setups extending to remote hardware and cloud. Free and open source with no AI upsells. Coasts is a product of Coasts.
