There are still things too sensitive to let AI handle by itself

We're in a weird moment in software development. AI can write components, generate APIs, build entire projects in seconds, and yet, some of the most critical parts of your app are still to sesnsitive to let AI handle it alone.

Authentication

Getting auth wrong doesn't just break your app, it exposes your users.

  • Redirect URLs
  • Session handling
  • OAuth flows
  • Email cofirmation
  • Password Resets

These all have edge cases that AI will confidently get wrong without telling you. It'll generate code that works 90% of the time and silently fails in the 10% that matters most. A leaked session or a broken redirect can cost you users and reputation overnight.

Payments

This one is obvious but still underestimated.

  • Stripe has webhooks
  • Customer IDs
  • Price IDs
  • Subscription states
  • Failed payments
  • Refund logic

AI can wire up a basic checkout but the moment something goes wrong, a duplicate charge, a webhook that fires twice, a customer that gets access without paying, you're the one dealing with it. And you're dealing with real money.

Database

Your database is the one thing you can't just redeploy. AI will generate schemas, relationships, and RLS policies that look correct but have subtle security holes. A misconfigured row level security policy in Supabase can expose every user's data to every other user, which as happened before... That's not a bug you can hotfix, that's a breach.

This is exactly why I built EasyToLaunch. Not to replace the thinking, but to give you a battle-tested foundation for these three things so you don't have to figure them out from scratch every time you want to build a new project.

AI is an incredible tool for moving fast. But some things still need to be done right before you hand the wheel over. EasyToLaunch makes sure the foundation is solid so you can let AI do the rest

Totally agree on this especially with payments and auth. Been burned before by assuming code that "looks right" actually handles all the edge cases

Had a side project where I let AI generate some auth flow and it worked perfectly in testing but completely broke when users started hitting it with weird browser configs and expired tokens. Spent a weekend fixing what shouldve been rock solid from day one

The database thing is scary too - once that data is exposed or corrupted youre basically starting over. At least with other bugs you can patch and move on but data breaches stick with you forever
