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.

The problem

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
The solution

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
Shield · for OSS maintainers

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.
