SafeJSON vs codebeautify.org
codebeautify.org was part of the same November 2025 credential leak that exposed 80K+ snippets. SafeJSON removes that failure mode by processing JSON locally in your browser.

The codebeautify.org incident
The reported 2025 exposure affected jsonformatter.org and codebeautify.org. For developers pasting logs, API responses, tokens, configs, or customer data, the problem is not only one incident. The problem is any workflow where sensitive JSON leaves the browser.
How to verify any JSON tool
- Open the tool in your browser.
- Open DevTools and switch to the Network tab.
- Paste JSON and run the formatter, viewer, diff, decoder, or parser.
- If a new request contains your data, the tool uploaded it. SafeJSON shows zero new requests while processing JSON.
