Supabase Studio Multi

The tool extends the standard Supabase Studio UI to create, run, and monitor several isolated Supabase stacks from a single self‑hosted dashboard. It replaces the default Studio container with a multi‑head version that can launch additional projects on demand, using the host Docker socket rather than Docker‑in‑Docker, and automatically assigns each project a distinct port block.

Each project receives its own credentials—including Postgres password, JWT secret, anon key, and service key—ensuring isolation. Existing self‑hosted installations can be upgraded with a single command, preserving data, and remote Supabase deployments can be registered for centralized browsing. The interface also supports standby instances with one‑click failover and, in an enterprise mode, a master‑replica cluster that auto‑promotes healthy replicas.

Designed for developers and teams that self‑host Supabase and need multiple environments such as staging, client projects, or separate databases, the solution aims to simplify management without requiring a Supabase Cloud account or manual Docker Compose configuration.
