NerdeRegion

NerdeRegion is a developer tools extension for debugging live regions on a Web Page. When activated, it lists all active Aria live regions, and keeps a record of all mutations that has happened on the region.

You can use NerdeRegion to,

• Check if a live region is being updated properly,
• Check if accessible name computation (beta) is done correctly,
• Check if live region is being re-used correctly.

To use the extension, open your browser’s Developer Tools, and navigate to the NerdeRegion tab.

NerdeRegion is a free and Open-source project. You can contribute to its source code, or create support requests on GitHub.
