Architecture rails for AI-built SaaS.
Skip the boilerplate. Superstarter ships the architecture every modern SaaS needs — auth, database, deploys, MCP plumbing, parallel-agent worktrees — so you can spend your time on features, not foundation.
// 04 / system
What's included
-
01 · Auth
better-auth on day one
Magic links, OAuth, sessions — wired into the database, the API, and the CLI without configuration.
-
02 · Database
Neon + Drizzle, per-worktree branches
Postgres branches spin up per worktree so parallel agents don't race on shared state. Migrations tracked, not freelanced.
-
03 · Deploys
Render with PR previews
Every pull request gets its own preview URL. Production deploys on merge. Zero config to add a new app.
-
04 · MCP
Pre-wired roadmaps + tooling
Claude can plan, prototype, and ship through MCP servers configured from the first clone.
