Group, filter and interpret messy or semi-structured logs with local patterning, categories, anomaly hints and a mini timeline.
Production logs rarely arrive in a neat, single format. They mix structured and unstructured lines, broken stack traces, noisy success events and inconsistent timestamps. A useful analyzer should recognize structure when it exists, fall back safely when it does not, and still group recurring templates so the meaningful problems rise to the surface. This tool focuses on that first-pass triage entirely in the browser.
Paste the code into your HTML and the tool shows up on your page, without J-Kit's navigation and ads. It still runs in the browser of whoever visits your site.

Yes. When the tool recognizes known structures such as Nginx, syslog, Docker build, JSON lines or logfmt, it uses dedicated parsers. When it does not, it falls back to a conservative generic parse instead of failing outright.
Drag and drop a file into the area above or paste raw text. Analysis runs locally and tries to stay useful even when the format is mixed or imperfect.
Processing stays local. Your logs never leave the device; only generic usage events may be counted, never the analyzed content itself.
