Free Log reviewer: Explore logs and review them for leaked secrets, log injection and missing fields.

A log explorer and log security review in your browser. Open web access logs, JSON application logs, syslog or key=value logs: search them (free text or field queries), see top values per field and a timeline, and inspect any entry. The Review tab flags passwords, tokens, card and Aadhaar numbers written to logs, log injection, missing who/when/where/outcome fields and repeated sign-in failures, and downloads a redacted copy. Comes with three sample logs from a demo bank; your own files are read locally and never uploaded.

Free, no login, nothing to install. Your work stays in this browser.
