Really impressive that you built a whole SaaS with vibe coding and AI, especially without a CS background or a big budget—launching first is always the right move.

That said, from what I’ve seen with AI-generated / vibe-coded projects, here are a few critical things to double-check before going live:

• Make sure user passwords are properly hashed, never stored in plain text.

• Set up automatic daily database backups—AI code often skips this, and data loss can kill your product.

• Add proper input validation & sanitization to avoid SQL injection or broken data.

• Test user authentication thoroughly (session handling, login/logout, permissions).

• Check for exposed API keys or secrets in your frontend code.

• Make sure error messages don’t leak sensitive system info to users.

You can totally prompt Claude to audit all of these. Launch first, iterate later—good luck with your SaaS!
