AI Starter Kit Launch Readiness Benchmarks
Almost every vibe-coded project starts from an open-source template. We audited the most popular AI starters across our 108 launch readiness checks. See what headers, guards, and webhook defenses are missing before you ship.
Vercel AI Chatbot Starter
Maintained by Vercel / Next.js Team
"Incredible DX and streaming UI, but missing CSP headers and unthrottled chat endpoints leave you vulnerable to token depletion attacks."
What This Starter Gets Right
- •Server-only API key isolation (zero client key leaks)
- •Strict TypeScript types across all UI routes
- •Solid session handling with NextAuth / Auth.js
Gaps You Must Patch Before Launching
next.config.mjs does not declare CSP or X-Frame-Options headers.
Chat API route lacks IP-based rate limiting or token usage ceilings.
Error handlers may send raw prompt messages to external logging.
1-Click Fix Prompt for This Starter
Paste this prompt into Cursor or Claude Code to patch the out-of-the-box gaps in this template:
Refactor my Vercel AI Chatbot starter before launch: 1. Add strict security headers to next.config.ts including Content-Security-Policy, X-Frame-Options: DENY, and X-Content-Type-Options: nosniff. 2. Add Upstash Redis rate limiting to /api/chat so unauthenticated IPs cannot burn our Anthropic/OpenAI API credits. 3. Sanitize error responses in route handlers so internal server errors do not leak stack traces.
As soon as you add new routes, components, and Stripe products, new bugs sneak in. The Founder Pass ($15 one-time) scans your exact repository across all 108 launch criteria.
