The missing layer.

Everyone builds the input side. Everyone monitors the output side. Nobody checks whether the code is compatible before it merges.

Rosentic
Checks every PR against every other PR. Cross-branch. Cross-agent. Cross-language.
Compatibility verification
GitHub
GitLab
Bitbucket
Build, test, deploy
Tests merged code. Catches if it compiles and tests pass.
GitHub Actions CircleCI Jenkins
Monitor production
Is it running? Is it fast? Is it healthy?
Datadog Chronosphere New Relic
Every layer exists except one.

Agents have their own review tools. Repos have CI. Production has monitoring. Nobody checks whether all the agents' code is compatible with each other before it merges. That's the gap. That's Rosentic.

Inside your PR

What it looks like inside GitHub.

Rosentic comments directly on the line that breaks other branches. Engineers see the impact before they merge - without leaving the PR.

Breaking
This function has 5 callers on 3 other active branches that still pass 2 arguments. Adding required parameter shipping_address will break them when both branches merge.

Good catch - the bulk-orders branch is mine too, I'll update it. But the checkout branch was from last sprint, @mike is that still active?

Rosentic comments on the exact line. Engineers collaborate in the thread natively.

Compatibility monitoring, everywhere you work.

Every surface shows the same data at a different moment - while typing, before pushing, on the PR, and across the team.

1
PR Comment Live

Automatic scan on every PR. Conflicts posted as a comment. Zero config.

2
Interactive Report Built

Full drill-down from the PR comment. Severity tiles, root cause grouping, source context.

3
GitHub App + Dashboard Next

One-click install from GitHub Marketplace. All repos in one view. Conflict trends, agent activity, resolution workflow.

4
CLI + IDE Planned

Scan from your terminal before pushing. Real-time warnings in VS Code, Cursor, and JetBrains while you code.
