APQ Debugger (Beta) is a Chrome extension developed by Ish Abbi. This tool falls under the Browsers category, specifically in the Add-ons & Tools subcategory. The extension aims to enhance Apollo's persisted queries by intercepting them and prompting the system to retry requests by sending the complete GraphQL query.

Apollo's automatic persisted queries (APQs) and persisted queries are features that allow clients to execute GraphQL operations using an operation's ID instead of the entire operation string. This ID, typically a SHA256 hash, is cached in the application memory. The APQ Debugger (Beta) plugin, through specified regex, intercepts GraphQL queries, triggering Apollo to retry the query by sending the complete operation string.
