Quickly inspect application logs by severity, timestamp and repeated message. This lightweight analyzer works with pasted text in your browser and does not upload log contents.
Analyze application logs and debug errors
Application logs can contain hundreds or thousands of lines, making it difficult to find the first failure or repeated exception. This online log analyzer scans pasted text, classifies common severity labels, groups repeated messages and highlights likely stack-trace lines to make an initial investigation faster.
How to analyze log files
- Copy a relevant section of your application log.
- Paste it into the log input area.
- Select Analyze Logs to count severity levels and identify repeated messages.
- Filter the results by ERROR, WARNING, INFO or DEBUG and inspect matching lines.
Log analysis limitations
Log formats differ across PHP, Laravel, Symfony, Node.js, Java and infrastructure platforms. This tool uses text-based heuristics and cannot determine root cause, reconstruct distributed traces or replace a production observability platform. Review surrounding context and correlate errors with request IDs and deployment changes.
Frequently asked questions
Can it analyze Laravel and Symfony logs?
It can classify common severity labels and show stack-trace-like lines in plain-text logs from these frameworks, but it is not a framework-specific parser.
Does it find the root cause automatically?
No. It helps organize and filter log text. Root-cause analysis still requires application context and investigation.
