Code you'd actually approve in review.
Master writes the boilerplate you have written a hundred times, in a stack you already know, into a repository you own outright.
Three reasons engineers keep it.
Skip the first 20 hours
Auth, schema, migrations, routing, CI-ready structure. The part nobody enjoys is done before you open the editor.
It's your repository
Standard React, TypeScript and Postgres, synced to GitHub. Branch it, review it, take it elsewhere — no lock-in.
Stop being the ticket queue
Let product, ops and marketing build their own tools inside guardrails you set, and review the diffs.
Agent for the tedium. You for the decisions.
Nothing is hidden behind a builder abstraction — it is files, commits and migrations the whole way down.
- Scaffold
One prompt, working baseline
Typed routes, server functions, database schema and row-level security in place from the start.
- Iterate
Agent does the boilerplate
CRUD screens, forms, validation and tests, while you keep the architecture decisions.
- Review
Read the diff
Every change is a normal commit. Nothing is generated into a black box.
- Own
Continue in your IDE
Clone, run locally, deploy anywhere. Changes sync back both ways.
"I expected generated spaghetti. I got a typed router, sane migrations and RLS policies I would have written myself."
"Internal tool requests dropped by half. Ops builds their own and I review the pull request."
Prompts engineers start with.
Engineering questions, answered.
What exactly is the stack?+
React with TypeScript, TanStack Router and Query, Tailwind, and Postgres with row-level security. Server logic runs as typed server functions.
Can I keep working locally?+
Yes. Connect GitHub and the repository syncs both directions, so your IDE and Master stay in step.
How is quality enforced?+
Builds run through automated guards for routing, imports, data contracts and security before anything reaches the preview — and you still review the diff.
