What MagentaA11y is
MagentaA11y is a free, open-source accessibility testing checklist generator from T-Mobile. It provides acceptance criteria for web and native app components, with tailored criteria, code samples, testing steps, and practical guidance based on a selected technology stack and component. Web checklists cover keyboard use plus desktop and mobile screen-reader testing, with examples referencing NVDA, JAWS, VoiceOver, and TalkBack. Native app guidance covers iOS and Android, including screen-reader gestures, output checks, and device settings. The search-input checklist offers Gherkin, condensed, and WCAG views. An MCP server named magentaa11y-mcp connects coding agents and AI assistants to the testing criteria, while more AI enablement tools are in development. The project uses the Apache-2.0 license and is deployed through GitHub Pages. Issues, suggestions, and contributions can be submitted through GitHub issues or pull requests. The site presents it for user-story writers, developers, and accessibility auditors.
