Copy Synta?

Build me a SaaS web app like Synta.

Synta does: A premium model context protocol (MCP) server and web app designed to turn AI clients like Claude, Cursor, and OpenClaw into expert n8n workflow architects, with over 300+ businesses using it daily to It reportedly makes about $15k/mo, so the core idea clearly has demand — I want a lean version I can run and charge for.

Build it from scratch with a modern stack (Next.js + Tailwind + a simple database). Keep it shippable in a weekend.

Requirements:
- Nail the single core loop that Synta is known for — build that end to end first.
- The main dashboard/workspace where users do the primary task, with sensible empty states.
- Any AI step that makes it feel modern (generate, summarize, or automate the tedious part).
- Data persistence, search/filter, and a clean history/list view.

Also:
- Clean, modern, responsive UI with a thoughtful landing page.
- Email/password auth and a simple paid tier (Stripe test mode) so it's ready to charge.
- A README covering setup, environment variables, and how to deploy.

Ship a working MVP I can run locally first, then help me deploy it.
