Log Formatter
Paste JSON, nginx, Docker, syslog, or plain logs to normalize, filter by level, and inspect them locally in your browser.
Sensitive logs never leave your browser. Formatting, parsing, and filtering all happen locally.
Paste JSON logs, nginx access/error lines, Docker logs, or syslog entries. TeaFun normalizes them locally and lets you filter by level or search terms.
Frequently Asked Questions
Which log formats are supported?
The formatter recognizes structured JSON logs, nginx access/error logs, Docker stream output, syslog-style lines, and plain level-prefixed logs. Unknown lines are still shown as plain text.
Are logs uploaded anywhere?
No. Logs stay in the browser for parsing, filtering, and copy/export actions.
Why are some lines marked as plain?
If a line does not match one of the known formats, it is kept as plain text so you can still search it and inspect it without losing any content.
