cspace
Spin up per-task microVM dev environments with friendly hostnames, browser sidecars, and a Claude Code agent — clean host, no Docker, no proxy. macOS-only.
What’s in v1
Section titled “What’s in v1”- Per-sandbox microVMs with their own routable IP on
192.168.64.0/24 - Friendly hostnames at
<sandbox>.<project>.cspace2.local, resolving identically from the host browser and from in-sandbox playwright - Loopback NAT so dev servers (vite, next dev, etc.) are reachable without
--host=0.0.0.0 - Cattle-not-pets persistence — host bind-mounts for clones and sessions survive
cspace down - Bun-based supervisor that resumes sessions across container restarts
- Auto-attach —
cspace updrops you into an interactiveclaudesession by default
