From monorepo to .local domains

Supbuddy detects your project structure and creates domains for each app.

Supbuddy scans your project and detects apps automatically

A full desktop app, not just a CLI

Run multiple Supabase projects in parallel. Edit config.toml with a visual UI. Monitor scripts. Manage everything from one place.

Monitor Tab

Watch requests flow through your domains in real-time

Configure Tab

Expand projects to see apps, services, scripts, and open the Supabase config editor

Everything you need for local development

A complete toolkit that works with your existing setup. Zero configuration, instant productivity.

DNS Server

Custom domains, any TLD

Your domains end with .local by default — accessible on your machine, your local network, and beyond. Or choose any TLD: .dev, .test, or your own. Built-in DNS server with wildcard support. Change the TLD once and all domains update instantly.

LAN + Tailscale

Access from any device

Your dev servers are not stuck on localhost. Share them across your LAN — test on your phone, tablet, or another computer with zero setup. Connect Tailscale for access from anywhere in the world. mDNS broadcasts .local aliases automatically.

Auto-detect

Monorepo-aware

Auto-detects Turborepo, Nx, and monorepo setups. Each app in your workspace gets its own domain — automatically mapped and ready to use. Active services show at a glance when collapsed.

Isolated VMs

Multiple Supabase projects, fully isolated

Run a full Supabase stack per project — Postgres, Auth, Studio, Storage, Realtime, Logflare — all at once, side by side. Each project lives in its own Docker-in-Docker environment, so ports never clash, databases never bleed across projects, and switching is one click. Stock `supabase start` only ever runs one; Supbuddy lets you keep them all warm and toggle which two are active on the free plan (unlimited on Pro).

Config UI

Visual config editor

Edit Supabase config.toml with a full visual UI — no more manual TOML editing. Configure auth, database, storage, and 10+ sections with form controls, validation, and automatic backups. Server Action allowedOrigins missing? Supbuddy detects it and gives you a paste-ready snippet for next.config.

Secure

Automatic HTTPS

A local Certificate Authority generates trusted certificates and installs them in your system keychain. Your browser shows the green lock — no warnings, no manual steps. Port forwarding routes real ports 80 and 443 to your apps.

✓ Certificate trusted by system

✓ No browser warnings

Live

Real-time monitoring

Watch every request flow through your domains as it happens. Filter by method, status, or domain. Inspect headers and timing. Live port status indicators show which services are running.

Powerful

Caddy-powered

A full production-grade Caddy server runs under the hood. Real reverse proxy with automatic HTTPS, WebSocket support, and hot-reloading config — not just a hosts file hack.

MCP

Your AI agent runs your dev environment

Built-in MCP server lets Claude Code, Cursor, Codex, Windsurf, Claude Desktop, and any MCP-compatible tool drive Supbuddy directly. Ask "spin up my project, restart Supabase, write the new env keys" and it just happens. Read access (mappings, projects, request logs, env keys) is free; destructive actions go through a plan/apply gate with full audit log and 7-day soft-delete recovery. One-click install for each editor.

Free to start. Pro when you need it.
