Log Redaction Preview

See what gets masked in your logs

Logs routinely capture sensitive data that should not be stored or shared, and redacting it is essential. This tool lets you paste logs to see what sensitive data, personal information, card numbers and more, gets masked, so you can share or store logs safely.

Why log redaction matters

Logs are written liberally and read later, and they frequently capture things they should not: personal data, card numbers, tokens, all sitting in plain text where anyone with log access can see them. Before sharing a log with support, a vendor, or a wider team, or before retaining it, the sensitive parts must be masked. Redacting in the browser means the raw log never leaves your machine, which is the whole point, since uploading it to redact it would be the very exposure you are trying to prevent. The tool recognises common sensitive patterns and masks them.

Share logs safely

It runs entirely in your browser, so nothing you paste is uploaded and the result is yours to copy straight into a project. Because it works client-side, you can use it on private code and data without anything leaving your machine.
