Rosentic

Rosentic is a GitHub Actions-based CI tool that detects cross-branch compatibility conflicts before they reach production. It scans every pull request against all active branches simultaneously, catching breaking changes like API signature mismatches, schema drift, and return type changes that single-PR code review tools miss entirely. Rosentic runs deterministically inside your own CI runner — code never leaves your infrastructure — and requires no signup or API key to get started.

• Cross-branch conflict detection — scans every active branch against the current PR, not just the target branch, to surface incompatibilities invisible to standard code review
• Breaking change classification — categorizes findings as Breaking or Likely Breaking with exact file paths and line numbers for fast triage
• Zero-trust execution — the scan engine runs entirely on your own GitHub Actions runner; no code is transmitted to external servers
• One-file setup — add a single YAML workflow file to .github/workflows/ and get verdicts in under 60 seconds with no API key or account required
• Multi-language support — covers 12 programming languages, validated across 150+ real-world repositories
• PR comment reporting — posts a structured Rosentic Review comment directly on the pull request listing all detected conflicts with context
• Free for open source — permanently free for public and open-source repositories
• Agent-aware — designed for repos where multiple AI coding agents (Cursor, Claude Code, Copilot, Codex, Windsurf, Factory) work in parallel branches
