I built a free 12-check launch preflight that runs in your browser

Launch Gate: a browser-only preflight for software launches

Before shipping a landing page or small web product, I kept repeating the same checks: page metadata, security-related response headers, link basics, and launch-page details that are easy to miss.

I turned that checklist into Launch Gate.

The free demo runs 12 passive checks in the browser:

  • no signup
  • no upload
  • no store or account access
  • results stay in the page

Try the free demo: https://launch-gate-demo.smagnezi8.workers.dev

There is also a $19 one-time pack with the full 96-check checklist, CSV, runnable agent skill, prompts, and a bounded passive scanner: https://buy.polar.sh/polar_cl_QY9LB3UtZ5IKRj9awKkapu0w67VJVNdkKnSCF4MARJe

This is a preflight checklist, not a security audit or certification. I would value feedback on which checks are most useful before launch and which are noise.

Disclosure: I built Launch Gate. This post was written with AI assistance.
