PayloadBench vs JSON Formatter Extension

The original JSON Formatter Chrome extension reached 2M+ users before being sold, closed-sourced, and turned into adware. PayloadBench keeps the code open and the JSON processing local.

Why ownership changes matter

Browser extensions can change owners, permissions, and bundled scripts. PayloadBench makes the web tool and extension source available for audit, avoids ads, and gives developers a simple Network tab verification workflow.

How to verify any JSON tool

  1. Open the tool in your browser.
  2. Open DevTools and switch to the Network tab.
  3. Paste JSON and run the formatter, viewer, diff, decoder, or parser.
  4. If a new request contains your data, the tool uploaded it. PayloadBench does not upload pasted JSON while processing it.
