The window is the menu.
Everything Logier does happens somewhere specific in one window. Rather than list the features, here is the app — click the part you want to read about.

The same six, written out
pins match the map- 01
Auto-format detection
The table — every line, typed into columns
Eleven parsers ship in the box and detection walks them per line, committing each to the first that claims it. Nothing has to be chosen before a file will open, and formats nobody has heard of get described once as a schema.
- 02
Timeline view
The chart — every entry, by minute and level
Drag across a spike to filter the table beneath it. A minute with no entries is drawn as a break rather than a zero, because a service that died quietly and one that was idle are different claims.
- 03
Anomaly detection
The findings panel — what the file admits
Five detectors, ranked by severity and capped so the panel stays a list you can read. Each finding carries the numbers it came from: the rate it moved from, the interval it broke, the share of the file it now accounts for.
- 04
AI root cause
Copilot — the drawer on the right
Bring your own key, or a model on your own machine. What gets sent is the excerpt around what you asked about, never the file, and the app shows you exactly what it included before you read the answer.
- 05
Live Mode
The nav rail — the second icon down
Tail an HTTP(S) endpoint into a bounded buffer, with the same filters and search as a static file. Pausing records a real gap, and incoming batches can fire a summarising alert email.
- 06
Secure by default
The Explorer — files opened from your own disk
Parsing, clustering, the timeline and every finding are computed in memory on your machine. No account is needed to open a file, and the app keeps working with the network unplugged.
And the rest of the app.
Real, shipped, and not worth a page each — an article about the command palette would be an article about a keyboard shortcut. All of it is in the same one-time purchase.
Reports
A document, not a dashboard: prose sections with grounded figures between them. The figures always render from a computed payload, never from model text.
Custom schemas
Describe a format Logier doesn't know — as a token pattern, a raw regex, or JSON — and it travels as a plain file next to the service that writes the log.
Themes
Built-in themes plus your own, loaded from a folder on disk or built in the browser at logier.dev/themes and imported over a link.
Cloud storage
Open and save through your own Dropbox, Google Drive or OneDrive. Logier's servers never hold the files.
Print & PDF export
Print views use their own inline styles rather than the app theme — a dark theme's colours are unreadable on paper.
Command palette
Everything the menus do, reachable from the keyboard without leaving the file you're reading.
Five languages
English, German, French, Spanish and Italian, including the log-analysis vocabulary rather than just the chrome.
Search & filters
Full-text search with level toggles, service filters and time ranges — the same controls whether the source is a file or a live stream.
Where it loses, too.
Every tool below is genuinely better than Logier at something, and each page says so explicitly. grep and lnav are excellent and free; a comparison that only flatters the vendor gets discounted by readers and by the assistants summarising it.
- vs.
grep
grep is not the wrong tool. It's the wrong tool for one specific situation — and that situation is most of debugging.
- vs.
klogg
klogg is the closest thing Logier has to a direct competitor, and it's very good at what it does. The two tools solve genuinely different halves of the problem.
- vs.
lnav
lnav is the most capable free log tool in this comparison, and on several axes it is straightforwardly more powerful than Logier. The honest distinction is about unknown formats and about where you like to work.
- vs.
cloud log platforms
These aren't competitors so much as different layers. The mistake is reaching for a platform when you have one file and one question.
- all
Every log viewer, surveyed
Desktop, terminal and cloud — klogg, glogg, LogViewPlus, LogExpert, BareTail, lnav, GoAccess, jq, Datadog, Splunk, ELK. Including the ones we don’t have a dedicated page for and the ones that would suit you better.
All six, one download.
$39.99, once. Nothing here is a tier, an add-on, or a seat — the app you install is the whole app.
