mrge is an AI-powered code review platform that automatically reviews PRs and gives human reviewers superpowers. It’s tool of choice for fast-moving teams like cal.com and n8n.
Hey Product Hunt, Paul and Allis here – founders of mrge! 👋
We’re building mrge – an AI code review platform to help teams ship code faster with fewer bugs. Our early users include Cal.com, n8n, and Better Auth—teams that handle a lot of PRs every day.
We’re engineers who faced this problem when we worked together at our last startup. Code review quickly became our biggest bottleneck and quality tanked — especially as we started using AI to code more.
We had more PRs to review, subtle AI-written bugs slipped, and we (humans) found ourselves rubber-stamping PRs without deeply understanding the changes.
👷 We’re building mrge to help solve that. Here’s how it works:
Connect your GitHub repo via our Github app in two clicks (and optionally download our desktop app).
AI review: When you open a PR, our AI reviews your changes directly in a secure container. It has context into not just that PR, but your whole codebase, so it can pick up patterns and leave comments directly on changed lines. Once the review is done, the sandbox is torn down and your code deleted.
Human-friendly review workflow: Jump into our web (or desktop) app (it’s like Linear but for PRs). Changes are grouped logically (not alphabetically), with important diffs highlighted, visualized, and ready for faster human review.
💻 The AI reviewer works a bit like Cursor in the sense that it navigates your codebase using the same tools a developer would—like jumping to definitions or grepping through code.
⚡️ The platform itself focuses entirely on making *human* code reviews easier. A big inspiration came from productivity-focused apps like Linear or Superhuman, products that show just how much thoughtful design can impact everyday workflows. We wanted to bring that same feeling into code review.
That’s one reason we built a desktop app. It allowed us to deliver a more polished experience, complete with keyboard shortcuts and a snappy interface.
We think the future of coding isn’t about AI replacing humans—it’s about giving us better tools to quickly understand high-level changes, abstracting more and more of the code itself. As code volume continues to increase, this shift is going to become increasingly important.
