Paste raw log output and get error patterns, frequency clusters, and the anomalies that deserve a look, without shipping production logs to a third-party service.
Paste log output to analyze patterns, detect errors, extract stack traces, and get root cause suggestions. Supports JSON, syslog, Apache/Nginx access logs, and plain text.
The most frequent error is rarely the interesting one. It is usually a known noisy warning that has been firing for months. What matters is what changed. An error that was absent yesterday and appears a thousand times today, or one whose rate tripled after a deploy. Clustering by pattern rather than by exact string is what makes that visible, because the same underlying error appears with a hundred different request IDs.
Logs routinely contain tokens, connection strings, email addresses, and customer identifiers, which is why analysis running locally matters. Nothing you paste here is transmitted.
