Every log. One fast window.
DataraLog is a native log viewer for macOS and Windows. Open a 2 GB file in seconds, tail your servers over SSH, follow Docker and journald, and find the line that matters — without shipping your logs to anyone.
Everything you reach for when something breaks
Huge Files, No Waiting
DataraLog indexes logs where they live instead of copying them into a database. Multi-gigabyte files open in seconds and scroll smoothly from the first line to the last.
Explore Search →Local, SSH, Docker & More
Tail local files and folders, files on your servers over SSH, journald units, Docker containers and the output of any command — side by side.
Explore Sources →Understands Your Format
Filter Like You Think
Type text, level:error, status:>=500 or /regex/ and see results instantly. A histogram shows when it happened — drag across it to zoom in.
Patterns & Alerts
Millions of lines become a short list of message patterns. Spot spikes and brand-new errors at a glance, and get a desktop notification when it matters.
Explore Patterns →AI That Respects Secrets
Ask Claude or OpenAI what an entry means, with your own key. Passwords, tokens, emails and IPs are redacted first — and you see exactly what is sent.
Explore AI →Every source, one timeline
Your web server, PHP app, queue worker and database all write their own logs. DataraLog merges them by time so you can read the whole story of a request in order — and follow a request ID across every service with one click.
- Combine any sources in a workspace into one view
- Entries from every source interleaved by timestamp
- Trace a request or job ID across all of them
- Each source keeps its own colour so you always know where a line came from
From a wall of text to a short list
DataraLog groups similar messages into patterns, so two million lines become forty message types with counts, sparklines and error rates. Spikes and brand-new patterns are flagged automatically — the fastest way to answer “what changed?”.
- Messages grouped with variables like IDs and timings masked
- Sort by most frequent, most errors, newest or rarest
- Show or hide a whole pattern with one click
- Turn any pattern into an alert
