Show HN: PullMaster – Recommends code reviewers from your repo history
I've been a developer for 20+ years and reviewer selection has been a recurring problem at every company I've worked at. Either you're a CODEOWNER getting spammed on every PR, or you're in Slack trying to find someone who actually knows the code you changed. CODEOWNERS is too coarse — it maps paths to people, but doesn't account for who's available, who reviewed this author before, or who actually touched these files recently.
I built PullMaster to fix this. It's a GitHub App that analyzes your repo's actual history and recommends the best reviewer for each PR. It adapts to the risk level of each change, so critical PRs surface experienced reviewers while routine ones get distributed across the team.
Install the GitHub App and comment `@pullmaster-ai suggest` on a PR to get a recommendation with an explanation, or `@pullmaster-ai assign` to also request the review automatically. No configuration needed — it learns from your repo as soon as it's installed.
It's free. I'd use it at my day job but being in a heavily regulated industry without SOC 2 makes that a non-starter, so I'm looking for early users and feedback. Happy to answer questions about how it works.
