Local Filtering
Format production logs safely
Readable Dev Tools helps engineers format production logs, debug logs, server logs, and application logs locally in the browser. It highlights levels such as ERROR, WARN, INFO, and DEBUG, and can filter long log output without uploading data.
Browser-only log formatting is useful when logs contain request IDs, user IDs, internal paths, stack frames, or confidential operational details.
- Format ERROR, WARN, INFO, and DEBUG log lines.
- Filter logs by level, keyword, and time range.
- Extract request IDs and show context around errors.
- No data leaves your browser.
