themarch/dev

A reusable dev environment for TypeScript. Scaffold a SaaS B2B in 90 seconds, enhance an existing repo, or add features through composable skills.

What you can do

Scaffold a new project

themarch init my-app --template saas-b2b produces a working multi-tenant SaaS with Next.js + tRPC + Drizzle + Better-Auth in under 90 seconds.

Enhance an existing repo

themarch enhance . detects your stack and adds .cursorrules, CLAUDE.md, and the skills catalog without breaking anything. Idempotent.

Add a feature end-to-end

themarch add-feature invoices chains table → RLS → Zod → tRPC → page → e2e test. Dry-run by default.

Bring AI into your workflow

Three MCP servers ship in the box: query Postgres, run skills, read project docs from Claude or Cursor.

npx @themarch/cli init my-app --template saas-b2b
cd my-app
cp .env.example .env
docker compose up -d
pnpm db:migrate
pnpm dev
