Launch Check
Overview
A pre-launch report card for apps and sites built with AI tools (Lovable, Bolt, Replit, Cursor, v0, Claude).
scripts/launch_check.py loads a live URL the way a visitor's browser does, scans what it downloaded, and scores
four areas 0-100: security, phone design at 375 px, being found by Google and AI search, and speed and basics.
It ends with a plain-English fix list. Scores are heuristics over inspected evidence; review semantics and application-specific requirements rather than treating the tool as launch authority.
When to Use This Skill
- Use when the user asks "is my app safe to launch", "is my site ready", or wants a pre-launch checklist.
- Use when the user asks whether an API key leaked into the frontend ("did I leak my Stripe/OpenAI key").
- Use when the user asks whether their Supabase or Firebase database is open to anyone.
- Do not use for authenticated flows, API fuzzing or penetration testing (see Limitations).
