live tailing
A GUI alternative to
tail -f for remote logs
Tailing works when you have a shell on the box. Increasingly you don't — the service runs in a container you can't exec into, on a platform that only exposes logs over an authenticated HTTP endpoint, or on infrastructure that hands you a URL and nothing else.

What you'd type,
and what you'd click
The first few rows have a perfectly good CLI answer. The bottom half is where a pipeline runs out.
| Task | Shell | Logier Live Mode |
|---|---|---|
| Follow a log as it's written | tail -f app.log | Connect Live Mode to a streaming endpoint |
| Follow through log rotation | tail -F app.log | The stream is the source; rotation is the server's problem |
| Only show errors | tail -f app.log | grep -i error | Toggle the error level — no reconnect |
| Change what you're filtering | Ctrl-C, edit the pipeline, run it again | Toggle a different level; the buffer is still there |
| See how often it's happening | Not available | The timeline builds live as entries arrive |
| Distinguish new errors from repeats | Not available | Clustering counts repeats; new signatures are flagged |
| Keep what you saw after stopping | tail -f app.log | tee capture.log | Snapshot the buffer to the editor |
| Authenticate to a protected source | Whatever SSH gives you | Custom request headers, including bearer tokens |
when to just use tail
tail -f is still right
more often than not
If you have a shell on the machine and a path to the file, nothing here beats typing eleven characters. It's already installed, it composes with every other tool you have, and it works over SSH where a desktop application simply cannot follow. The case for a GUI starts at the point where you can't get that shell — or where you need to change what you're filtering without losing everything that already scrolled past.

Live Mode
The full feature: endpoints, auth headers, buffer limits, and what you can do mid-stream.
Logier vs. grep
The same argument for static files — when line matching is enough and when it isn't.
Timeline view
The chart that builds itself while a stream is running, so you watch an incident form.
Logier vs. lnav
lnav's follow mode survives rotation and works over SSH. An honest comparison.
Tail what you can't SSH into.
Point Live Mode at any streaming endpoint you're already authorized to reach.
