Before I share an app with users, I want to know what I’ve actually tested.

That’s why I’m building a security scanner alongside a Launch Check.

The scanner examines code for exposed secrets, risky authentication patterns, dependency issues, and common security flaws—with explanations and suggested fixes.

Launch Check opens the deployed app in a browser, explores accessible pages, and captures screenshots, console errors, failed requests, and load times.

Together, they help answer two practical questions:

• What in the code needs attention?

• What problems appear when someone visits the deployed app?

The workflow is simple: scan → review → fix → retest.

Browser checks cover accessible pages; signup, payments, and other form-based journeys still need dedicated testing.

I’m looking for feedback from fellow builders: what’s the one issue you’d want caught before your first user finds it?
