Prelint: The AI Reviewer That Catches Product Drift, Not Bugs
Prelint is a GitHub and GitLab app that reviews every pull request against a team's product specs, ADRs, and prior decisions rather than against the code itself, targeting what it calls product drift: technically correct code that quietly contradicts decisions the team already made. It launched on Product Hunt on July 29, 2026, taking #1 Product of the Day and #1 Product of the Week with 676 points. The core architecture is a decision ledger that weighs the authority of each decision and supersedes rather than deletes entries, exposed to agents through a CLI and MCP server. Prelint's own research across 56,706 public pull requests found that docs context raised the reviewer flag rate from 13.3% to 36.6% at 80.8% precision. Pricing is $1 per completed review with no seats, and public repositories are free.
