You're one person, you write TypeScript, and the AI feature is the product. You want real users signing in and paying by Monday, and you'd rather pay a little per month than run servers.

79 makers' products and 69 open-source projects use at least half of these 9 tools.

# Stack: Ship an AI SaaS this weekend

You're one person, you write TypeScript, and the AI feature is the product. You want real users signing in and paying by Monday, and you'd rather pay a little per month than run servers.

Use these tools. Ask before swapping one for an alternative.

- Frontend Framework: Next.js — https://nextjs.org
agent docs: https://nextjs.org/llms.txt · CLI: npx next
Why: The default most makers and AI coding agents reach for; pages, API routes and streaming responses in one project.
- Database: Supabase — https://supabase.com
agent docs: https://supabase.com/llms.txt · MCP server: com.supabase/mcp (https://mcp.supabase.com/mcp) · CLI: npx supabase
Why: Postgres, file storage and auth in one project, so there's one dashboard and one bill while you find out if anyone cares.
- Authentication: Supabase — https://supabase.com
agent docs: https://supabase.com/llms.txt · MCP server: com.supabase/mcp (https://mcp.supabase.com/mcp) · CLI: npx supabase
Why: Already in the same project as your data, and row-level security ties each row to the signed-in user.
- Payments: Stripe — https://stripe.com
agent docs: https://stripe.com/llms.txt · MCP server: com.stripe/mcp (https://mcp.stripe.com) · CLI: npx @stripe/cli
Why: The most-used payment API among makers here, with hosted Checkout and a customer portal so you build no billing pages.
- Transactional Email: Resend — https://resend.com
agent docs: https://resend.com/llms.txt
Why: Sign-in links and receipts from a simple API, with templates written as React components.
- LLM API: OpenAI API — https://openai.com
agent docs: https://developers.openai.com/llms.txt
Why: The widest set of examples and models; swap in Claude or Gemini later without touching the rest of the stack.
- AI SDK & Agent Framework: AI SDK — https://ai-sdk.dev
Why: Streaming chat UI, tool calls and structured output in TypeScript, and a one-line switch between model providers.
- Hosting: Vercel — https://vercel.com
agent docs: https://vercel.com/llms.txt · MCP server: com.vercel/vercel-mcp (https://mcp.vercel.com) · CLI: npx vercel
Why: Push to deploy, preview links for every branch, and made by the team behind Next.js.
- Error Monitoring: Sentry — https://sentry.io
agent docs: https://sentry.io/llms.txt · MCP server: io.github.getsentry/sentry-mcp · CLI: npx sentry
Why: See the stack trace a user hit before they email you about it; a free tier covers an early product.
- AI Coding Assistants: Claude Code — https://claude.com/product/claude-code
agent docs: https://claude.com/llms.txt
Why: An agent that reads the repo and runs commands — and every pick above has docs or an MCP server it can use.

Trade-offs: Three vendors hold your data, your users and your payouts, and every bill grows with usage — fine at a hundred users, worth revisiting at ten thousand. Stripe leaves sales tax and VAT to you; if you sell worldwide from day one, see the merchant-of-record stack.
