Skip to contentCompare Tentaco vs JSONLint: local JSON formatter and validator, no paste logging, free bulk checks.
JSONLint is a classic paste-and-validate site for quick JSON syntax checks. It works well for public samples but sends your payload to their servers.
Tentaco JSON Formatter validates, pretty-prints and minifies in your browser — ideal for API keys, config files and production payloads you do not want logged.
| Feature | Tentaco | JSONLint |
|---|---|---|
| Server upload | No — local parse | Yes — paste to server |
| Pretty print | Yes + minify | Validate focus |
| Account | Not required | Not required |
| Privacy | On-device | Third-party logs possible |
| Price | Free | Free |
Use Tentaco for sensitive JSON without server paste. JSONLint remains fine for anonymous public snippets.
