Show HN: Horizontally Scale Localhost

Score: 7.0/10 (Innovation: 7, Technical: 7, Documentation: 8, Utility: 6)

Coasts is a CLI tool that creates isolated, containerized development environments for multiple Git worktrees on a single machine, enabling developers to work on multiple branches simultaneously with full environment isolation. It's interesting because it provides local-first observability with a web UI, works with existing Docker Compose setups, and now supports remote execution to offload resource-intensive environments.

Target audience: backend devs, devops, full-stack developers
