AI broke pull requests. We built the fix.
Stop scrolling.
Start reviewing.
Two products. One GitHub App. Shield triages incoming PRs for OSS maintainers drowning in AI contributions. StructPR organizes the rest by business impact, with churn, coupling, and reviewer suggestions baked in.
The PR review approach others are now copying — we built it first, we ship the half they haven't.
GitHub's file list destroys context
Auth changes scattered across 15 files. Migrations buried 200 files away from the API they power. You spend 30 minutes understanding what should take 5 minutes to review.
- × 500-line PRs sit for days because no one wants to start
- × Reviewers ask "what does this PR do?" in comments
- × Bugs ship because you missed the migration 200 files away
PRs organized by business impact
StructPR automatically groups files by business logic: Authentication, Payment Processing, Database Migrations, Tests. Review the auth flow in one pass instead of jumping between files.
- Smart grouping reduces chaos (typically 3-7 groups per PR)
- Risk indicators flag critical changes first
- Works with existing PRs—no workflow change
- Commit replay mode shows each commit's intent step by step

Triage 50 PRs in two minutes.
Shield scores every incoming PR — needs_human, vouching_required,
likely_slop
— with
confidence and explainable reasons. You scan. You pick the five worth
reading. The rest don't burn another minute of your week.
Triage before review
Every other tool runs after you've decided a PR is worth reading. Shield is the layer before that decision. It tells you which five PRs deserve your attention out of fifty.
Published methodology
Built on the MSR 2026 Circuit Breaker paper (arXiv:2601.00753). Every signal cited, every threshold justified. Read the methodology →
Read-only until earned
v1 is private. We don't post on PRs, apply labels, or auto-close anything. The contributor sees nothing until our verdicts match your decisions for four weeks — AUC ≥0.80, FP rate ≤2%.
Four design-partner slots this quarter.
Free for verified OSS projects. No contract, no credit card, no SLA promises. Spend four weeks privately checking our verdicts against your own. Walk if it doesn't help.

Intelligence built in
StructPR doesn't just organize your files—it actively helps you catch what matters and skip what doesn't.
Review Briefing Panel
Get an at-a-glance summary of what the PR does, key risk areas, and review priorities before you read a single line of code.
Missing Change Detection
Flags coupled files that typically change together but were left out of the PR. Catch forgotten migrations, missing tests, and incomplete refactors.
Suggested Reviewers
Recommends the best reviewers based on recent commit history in the affected files. Stop guessing who knows this code.
Repository analytics
Understand your codebase health with analytics derived from your commit history—no agents, no AI guessing.
Code Churn Analysis
Identify hot spots—files that change too often, accumulate bugs, or resist stabilization. Focus refactoring where it matters.
Bus Factor Warnings
Detect knowledge silos where only one person has touched critical files. Reduce risk by spreading ownership before it's too late.
Coupling Detection
Map hidden dependencies between files that always change together. Surface architectural coupling that code structure alone doesn't reveal.
What makes StructPR different
Deterministic, not AI-powered
Pattern-based grouping. Same PR = same grouping every time. Typically completes in under 2 seconds.
Zero workflow change
Works with your existing PRs. No stacked PRs, no new Git commands. Install today, faster reviews tomorrow.
Execution flow visualization
See how requests flow through changed files—from routes to controllers to database changes. Review in the order code executes.
Commit replay mode
Step through commits chronologically with keyboard shortcuts (j/k). Understand the author's intent before reviewing the full diff.
