HeyDeer

HeyDeer is built around a single, focused job: reviewing pull requests on GitHub. Rather than acting as a general coding assistant, it plugs into the PR flow as an independent reviewer, examining each change and reporting problems before merge. The pitch is precision at a low cost, with a free tier for individuals and teams and paid plans starting at $9 per month.

The core workflow is simple. You open a pull request, and HeyDeer reviews it automatically. From there, Autopilot lets the tool act on its own findings, fixing what it detected and repeating until the PR is ready to merge. The site also highlights that it works regardless of which model produced the code, listing Codex, Claude Code, Cursor, and human authors as equally reviewable sources.

HeyDeer is aimed at developers and small teams who want a second pair of eyes without adding seats or heavy process. The published comparison against GitHub Copilot, claiming 78% more issues found on the same pull requests, is presented as evidence of depth. Teams already using AI coding tools may find the independent-review angle particularly relevant.

Getting started requires no credit card, and installation is described as a two-click process. A sensible approach is to trial it on a few real PRs, compare its findings with your existing review habits, and only then enable Autopilot on branches where automated commits are acceptable. Overall, HeyDeer is a narrow but practical addition to a GitHub-centered workflow.
