Logier · desktop log viewer
Stop hunting.
Start fixing.

$39.99 once — not a subscription.
With Logier
Raw Logsprocess
Three steps from chaos
to clarity
Open or paste
Drop a log file into Logier or paste lines directly. Any size, any format — nothing is uploaded first.
Instant analysis
Format detected, entries parsed, errors clustered, and anomalies scored — all locally, in memory.
Fix faster
Jump to the root cause with one-click filters, a timeline view, and an optional AI explanation.
why logier
Built for the moment
you're debugging —
not the infrastructure
around it.
Any log. No setup. Answers in seconds. Here's what that actually means once you're using it.
Zero setup, zero infrastructure
No agents, no schemas, no ingestion pipeline to stand up. Drop a file or paste from the clipboard, and Logier is already parsing it.
Detected automatically, not configured
Apache, syslog, SSH, Android, and more — Logier finds your format on its own, with a fallback parser for anything else. No dropdown to hunt through first.
Built for debugging, not monitoring
Not another dashboard to maintain. Open it when something's already broken, get an answer, close it — Logier isn't asking you to babysit it 24/7.
Your data stays yours
Logs are parsed and analyzed in memory, on your machine. Nothing is uploaded by default — no account required just to open a file.
Pay once. Own it.
$39.99, one time. No seat pricing, no usage tiers, no monthly bill that creeps upward the more useful the tool becomes.
features
Everything you need to
debug at speed
Auto-format detection
Apache, syslog, SSH, Android, Spark, Zookeeper, and more — Logier identifies your format automatically, with a fallback parser for anything else.

AI root cause
Copilot reads the context around an error and writes a plain-English explanation of what broke, when, and why.
Timeline view
Visualise error spikes over time. Pinpoint exactly when things started going wrong at a glance.
Anomaly detection
Sudden frequency changes, outlier values, and unusual patterns.
Secure by default
Logs processed in-memory, never leaving your system without consent.

actionable insights
why this exists
“At my company, we use an in-house CMS called 2sxc. Whenever I updated one of our clients' websites and something went wrong, I found myself digging through plain-text log files, searching for keywords like ‘error’ and trying to piece together what had happened. That made me wonder: why isn't there a tool that can visualize and make sense of any log format I encounter? That's how the idea for Logier was born.”
