Problem (Pain Level: 7/10)

“7 out of 10 PRs I get these days are AI-generated garbage” - The new pain for open-source maintainers.

Current pain points:

  • AI Spam Flood: Low-quality PRs mass-generated by LLMs flooding open source projects
  • Time Waste: Maintainers missing real contributions while reviewing spam PRs
  • Tool Installation Resistance: Security concerns about GitHub App permission requests
  • Complex Setup: Most code review tools require excessive configuration
  • New Contributor Identification: Hard to distinguish real beginners from AI spam accounts

Target Market

Primary Target: Open source project maintainers, enterprise GitHub administrators

Market Size:

  • Code review automation market: $4B (2026)
  • GitHub public repositories: 100M+
  • Active open source projects: Millions
  • 35% of enterprises investing in AI-based dev tools

Pain Intensity: Spam PRs surging as AI coding tools proliferate

What is Slop Score?

A dead-simple AI PR spam detection service that works by just adding a badge to your README.

Core Concept:

<!-- Add one line to README.md -->
![Slop Score](https://slopscore.dev/badge/owner/repo)

<!-- Done! No installation, no permissions, no cost -->

How It Works:

  1. Analyze PR author’s profile (account age, followers, activity patterns)
  2. Review contribution history (PR acceptance rate, contribution types)
  3. Calculate heuristic-based reputation score
  4. Show detailed analysis page on badge click

Differentiators:

  • Zero Installation: Just add badge URL, no GitHub App needed
  • Zero Permissions: Uses only public APIs, no code access
  • Built-in Virality: Other projects naturally adopt after seeing the badge
  • Serverless: Near-zero cost with Cloudflare Workers
  • Transparency: Scoring logic is open source

Competitive Analysis

MarketLOWFree entry enables fast adoption
ExecutionLOW2-week MVP for quick validation

Key Risk: GitHub API rate limits (mitigated by caching)

  • Those with open source project maintainer experience
  • Those familiar with edge computing (Cloudflare Workers)
  • Those interested in viral growth
  • Those with a minimalist product philosophy
  • Those who understand the GitHub ecosystem well
