Prelint
Catches AI-written code that works but drifts from your actual product spec
What it is
Prelint reviews every pull request against your product specs, architecture decision records, and business rules, then flags spots where AI-written code technically works but drifts from what the team actually decided to build. It's built for teams whose engineers ship fast with AI coding agents but keep losing time to code that works yet misses the point. There's a free path for open source projects and a pay-per-review model with no seats, so small teams can try it without a subscription commitment.

What you get free vs paid
Verdict
Pros
- Checks pull requests against your own specs, ADRs, and business rules instead of generic code style
- Pay-per-review pricing with no seats, so cost scales with actual usage
- Free for open source projects, plus a startup program
- Specs live as markdown/YAML in your own repo instead of a locked-in dashboard
- On teams running multiple AI reviewers, a large share of the comments that actually get fixed come from Prelint's product-drift checks specifically
Cons
- Only useful if your team actually writes down specs, ADRs, or constraints for it to check against
- Narrower scope than a general code reviewer; it's not trying to catch bugs or style issues
- Newer product with a small independent track record outside its own Product Hunt launch
Worth adding alongside your existing AI code reviewer if your team already documents product decisions, since it catches a specific failure mode (correct code, wrong direction) that generic reviewers miss entirely.
