LOG ANALYZER
Find the event that explains what went wrong.
Open or paste logs, search for a clue, narrow the time range, and inspect the full event and its nearby context.
Download for Mac
Free download. Requires macOS 14 or later.
WHAT IT HELPS WITH
Move from a large log to one useful event.
Narrow the results
Search for plain text, include or exclude values, filter by severity, and choose a time range. The chart and interval control help you see when activity changed.
Inspect the evidence
Select a row to view the event, parsed fields, raw record, and nearby context without leaving the workbench.
INPUT LIMITS
Paste a sample or open the complete file.
Pasting is available through 20 MiB in both Free and Pro.
Free opens log files through 100 MiB. Pro opens log files through 500 MiB. Files above 500 MiB are not supported.
Search uses plain text. For advanced field matching, send the parsed events to Local Data and use a SQL query there.
