Catch when coding agents break each other before merge
Rosentic checks every PR against every other open PR before merge. When coding agents work in parallel, they break each other in ways no single-PR tool catches. Rosentic catches it. Deterministic analysis. Same scan, same result, every time. Most scans come back clean. That means you're clear to merge. Runs on your infrastructure. One YAML file, no signup, 60-second install.
Hey Product Hunt 👋. I'm Laramie. Nearly 20 years in tech. By day I run technical partnerships. By night I build with Claude Code and Codex on the same repo.
Here's what I kept running into: both agents write good code. Both PRs pass CI. Then they merge and break main. CI checks one branch at a time. Git merges text, not logic. Nobody checks whether the branches are compatible with each other.
With agent orchestration tools shipping weekly and PR volume exploding, this is only getting worse.
So I built Rosentic.
