About pseolint
pseolint is an open-source linter for programmatic SEO that detects the structural issues that get pSEO sites deindexed. Paste a URL in the web UI or gate checks in CI: it scores templates, finds doorway clusters, near-duplicates, and thin templates (the patterns SpamBrain treats as a single thin cluster). Includes a free tier and optional Pro monitoring for ongoing checks.
Key Features
- Template-level analysis to spot doorway gardens and thin clusters
- Detects near-duplicates and low-uniqueness templates that trigger SpamBrain
- Risk scoring per template and site overview
- Paste-a-URL web UI plus CI/API-friendly gating for automated checks
- Open-source with optional paid Pro monitoring
Who is this for?
SEO engineers, site reliability and growth teams working on programmatic SEO sites and developers integrating SEO checks into CI.
