features

Everything you need to
debug at speed

Auto-format detection

JSON, logfmt, Apache, syslog, custom patterns — Logier identifies your format in milliseconds. Zero configuration.

Error clustering

Similar messages collapse into one. See 'Query timeout ×47' instead of scrolling through 47 identical lines.

AI root cause

Claude reads your entire log and writes a plain-English explanation of what broke, when, and why.

Timeline view

Visualise error spikes over time. Pinpoint exactly when things started going wrong at a glance.

Anomaly detection

Sudden frequency changes, outlier values, and unusual patterns — flagged automatically even in quiet logs.

Secure by default

Logs processed in-memory, never stored without consent. SOC2-ready with full audit trail support.
