Replit + Claude API
The fastest way to go from idea to working AI-powered prototype, often in a single session.
The stack I prototype with
Replit gives me a persistent dev environment in the browser. Claude Code (or Claude API directly) gives me an AI pair-programmer that knows the whole repo. Together they collapse "I have an idea" → "I have a working prototype" from days to hours.
When this is the right tool
Anything where you need to validate an AI workflow before committing to a production build. Customer support triage. Document classification. RAG over a small knowledge base. Internal tools that don't need to scale beyond a team of five.
When to graduate from this stack
Replit is great for development; for production with real traffic, move to Vercel for the frontend and a hosted Postgres (Supabase, Neon) for state. Replit's deploy pricing scales worse than Vercel's once you're past a few thousand visitors a day.
I write more about this combo in the journal.
