Self-hosted dev sandboxes with preview URLs (Docker, Go, no K8s)
SMRTR summary
Sandboxed is an open-source backend engine for building AI app-builder products like Lovable or Bolt, deployable on a single server with one command. It spins up isolated Linux containers per user, runs a built-in AI coding agent, and serves live preview URLs automatically. Built on Go, Docker, Traefik, and SQLite — no Kubernetes required — it handles multi-tenant isolation, idle/wake cost control, and agent orchestration out of the box.
