DataraLOG
DataraLog is a fast, native log viewer for developers and self-hosters who need to see what their apps and servers are doing — right now. Open local log files of any size, tail logs on your servers over SSH, follow journald units and Docker containers, and capture the output of any command, all in one window. DataraLog understands Laravel, nginx, Apache, PHP-FPM, MySQL, Postgres, syslog, JSON and logfmt out of the box, colours every level, and handles rotated and compressed files without a second thought.
Find the line that matters in seconds. A simple filter language, a volume histogram you can drag to zoom, saved searches, bookmarks and a merged timeline across sources let you follow one request through every service. Pattern grouping turns millions of lines into a short list of message types, flags spikes and brand-new errors, and alerts can notify you on your desktop. Bring your own Claude or OpenAI key to have an entry explained — secrets and personal data are redacted before anything is sent, and you see exactly what goes out. Free for local files; DataraLog Pro unlocks remote sources, unlimited sources, patterns, alerts and AI.

- Custom parsers — day-first dates like 09.11.2026 14:05:00 are now read as timestamps.
- Settings — the licence section described another app's Free plan
