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

Launch Score
84/100
The Senior Dev Verdict

"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

SEC-042 (Missing Content-Security-Policy)high

next.config.mjs does not declare CSP or X-Frame-Options headers.

RATE-003 (Unthrottled LLM Endpoint)high

Chat API route lacks IP-based rate limiting or token usage ceilings.

OP-008 (Missing Sentry / Telemetry Scrubbing)medium

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.
