Rosentic

Catch when coding agents break each other before merge

Rosentic Introduction

Rosentic is a developer tool that checks every pull request against every other open PR before merge, catching cross-branch compatibility conflicts that single-PR tools miss. It provides deterministic, infrastructure-friendly scans with a simple YAML-based setup, ensuring codebases remain stable when multiple AI agents or developers work in parallel.

Key Features

Cross-PR conflict detection: scans each PR against all active branches
Deterministic analysis: same scan yields same results every time
Easy 60-second install: single YAML file, no signup or API key needed
Runs on your infrastructure: code never leaves your runner
Free for open source projects

Use Cases

Teams using multiple AI coding agents (e.g., Claude Code, Codex, Copilot) on the same repo to catch breaking changes across branches
Fast-moving startups with high PR volume and parallel development to prevent silent compatibility issues
Organizations maintaining large monorepos or microservices architectures where cross-branch contract drift can occur

Why Startups Use It

Startups rapidly adopt AI coding agents and parallel workflows, increasing the risk of silent cross-branch conflicts. Rosentic catches these conflicts before they hit production, saving costly debugging time and ensuring fast iteration. Its frictionless setup and free tier for open source make it ideal for resource-constrained teams.

Alternative Options

CodeRabbit, Graphite, Mergify, GitHub Actions, Semgrep

Frequently Asked Questions

What types of conflicts does Rosentic detect?

Rosentic detects schema drift, API signature mismatches, and other compatibility issues that occur when branches modify shared interfaces or functions.

Is Rosentic free to use?

Rosentic is free for open source projects. For private repositories, it offers a paid plan with additional features.

Does Rosentic send my code to external servers?

No. Rosentic runs entirely on your infrastructure (e.g., GitHub Actions runners); your code never leaves your environment.

How do I install Rosentic?

Installation involves adding a single YAML workflow file to your repository (e.g., .github/workflows/rosentic.yml). No signup or API key required, and it takes about 60 seconds.

Can Rosentic integrate with any CI system?

Currently Rosentic works with GitHub Actions, but it is designed to be extensible and may support other CI/CD platforms in the future.
