pour: Free Accessibility Checker and WCAG 2.2 Audit Suite

LinkTool

pour is a free, open-source accessibility auditing tool built directly on WCAG 2.2, providing DevTools panels, bookmarklets, a CLI, and a VS Code extension with no accounts or paid tiers.

Key points

  1. Built on WCAG 2.2: Features 88 automated rules assisting on 39 success criteria, alongside checklists for the 47 criteria requiring human evaluation.
  2. Integrates across development workflows via browser extensions (Chrome, Edge, Firefox), a bookmarklet, a VS Code extension, and a headless CLI for CI.
  3. Offers over 50 real-time simulations for visual, sensory, cognitive, and motor conditions, including colour deficiencies, tremors, and dyslexia.
  4. Runs entirely locally in the browser or terminal without transmitting data externally.
  5. Demonstrates high performance: Benchmarks across 138 websites show median speeds nearly 3x faster than axe-core, reaching up to 16x faster on large pages.

Why it matters

Ensuring WCAG compliance often requires fragmented or expensive tooling. pour simplifies accessibility testing by integrating directly into code editors, browsers, and automated deployment pipelines completely free of charge and with full data privacy.

Analysis

pour distinguishes itself through candour regarding the limitations of automated testing. Rather than claiming full automated coverage, it combines 88 rules for 39 criteria with structured manual checklists for the remaining 47. Its substantial speed advantages over standard engines like axe-core and its library of 50+ research-backed sensory and motor simulations make it a comprehensive tool for developers and designers alike.
