Browser Run - New Browser Run endpoint for accessibility trees
Cloudflare announced a new Browser Run endpoint for accessibility trees in its Developer Platform changelog on July 7, 2026. The endpoint provides programmatic access to accessibility tree data generated during browser sessions. This allows developers to retrieve structured accessibility information, such as ARIA roles, properties, and states, from web pages rendered by Browser Run. The feature is documented on the Cloudflare changelog page, which also includes instructions for fetching the page in Markdown format. The changelog entry does not specify pricing, availability tiers, or regional restrictions. Developers can use this endpoint to integrate accessibility testing into automated workflows, such as CI/CD pipelines, without needing separate tools. The documentation advises AI agents to request the Markdown version of the page to save context. This update expands the capabilities of Cloudflare's Browser Run service, which already supports headless browser automation for tasks like screenshotting and form submission.
Developers can now programmatically access accessibility trees via Browser Run, enabling automated accessibility checks in CI/CD.
