Developer Tools

General browser-side developer utilities: send and inspect HTTP API requests, generate dummy sample data, and compare text, code, or folders with clear diffs. Use this category when you are debugging integrations, preparing test payloads, or reviewing what changed between two versions—not when you only need JSON/SQL pretty-printing (that lives under Code Formatters) or Dynamics FetchXML/OData helpers (CRM Developer Tools).

How these tools help

Point the API tester at an endpoint you are allowed to call and read status, headers, and body. Generate dummy data that matches the shape you need for fixtures. Use compare when you want a side-by-side or unified view of differences.

Limits

Browser networking is subject to CORS and the target server’s rules. Dummy data is synthetic. Compare highlights differences; it does not merge or resolve conflicts for you.
