We just launched Prelint on Product Hunt 🚀
The bug isn't the scary part of AI-written code. Working code that quietly builds the wrong product is.

Prelint reads every PR against your specs, ADRs and prior decisions, and explains what the agent chose and why it matters — before merge. On teams already running other AI reviewers, ~40% of pre-merge fixes come from Prelint.
You can support here: producthunt.com/products/pre…
I've watched changes pass human review AND CI, then turn out to have broken an architectural pattern, added an unapproved dependency, or changed a permission rule nobody ever decided to change.
Nothing failed. It just wasn't what we agreed to build.

My friend left her MacBook Pro on a Manhattan park bench.

Within 6 hours: laptop in Bronx
After 7 days: in the Dominican Republic
Fascinating how stolen electronic logistic networks work, and how they don’t properly reset the hardware – at Downtown, Columbus
