IBM Equal Access
IBM open-source suite (v4.0.14.9999, March 2026) covering a11y checker browser extension, screen reader emulator (February 2026 prototype), and CLI for CI. Tests WCAG 2.1 Level A/AA + WAI-ARIA 1.2. Rule engine refactor in 2026 brought 70%+ perf improvement. First OSS implementation of a screen reader emulator directly in dev tools, direct testing without NVDA/JAWS setup.
Strengths
- Unique 2026 screen reader emulator prototype, direct testing without NVDA/JAWS
- IBM open-source, strong corporate sustainability, gov/banking adoption
- 70%+ perf improvement 2026 (rule engine refactor)
- CLI + browser extension + emulator = multi-modal coverage
Limitations
- Less WCAG 2.2 coverage than axe-core 4.11+ (focus on WCAG 2.1)
- No official MCP server to date, less agentic-friendly than axe-mcp
Best for
- IBM-aligned teams (gov, banking, healthcare) where Equal Access is mandated
- DS managers wanting an OSS screen reader emulator for a11y pedagogy
