The product often works. The landing page looks decent. But the boring launch-readiness basics are missing.

Things like:

unclear positioning above the fold missing security headers weak or missing privacy / terms pages no obvious trust signals poor mobile experience basic accessibility issues SEO metadata that has clearly been left until the end exposed implementation details in client-side bundles APIs that look like they may not be properly isolated or proxied

I’m curious what other people here check before they consider a web app “ready enough” to put in front of real users.

Do you have a personal launch checklist?

And for people who review a lot of early-stage products, what are the most common issues you see?
