# HoldUp > HoldUp is a developer-tool project for catching spec drift in pull requests before merge. Canonical site: https://getholdup.com/ ## What HoldUp does HoldUp compares code changes with the engineering context that was supposed to guide them, including: - product and engineering specs - architecture decision records (ADRs) - OpenAPI and GraphQL contracts - tickets and technical documentation A HoldUp finding should cite the source, explain the mismatch, and show possible downstream impact. ## Core problem A pull request can compile, pass tests, and still contradict the original requirement or engineering decision. AI coding agents can increase the speed and volume at which these mismatches occur. ## Product positioning HoldUp is not intended to replace tests, code review, static analysis, or existing spec frameworks. It is an intent-aware PR and CI check that works with the team's existing engineering context. ## Current stage HoldUp is in early pilot and customer discovery. ## Important pages - Homepage: https://getholdup.com/ - Examples: https://getholdup.com/examples.html - Guide: https://getholdup.com/guide.html - FAQ: https://getholdup.com/faq.html - About: https://getholdup.com/about.html
