-
Text filter, with Regex, Case and Invert toggles and inline match highlighting. The filter is kept in the URL (
?filter=...), so you can share a filtered view. - Level chips (Error / Warn / Info / Debug): hide or show a severity. They combine with the text filter. Lines with no detectable level (most access logs) are never hidden by the chips.
- Saved filters: name the current filter (with its regex/case/invert flags) to reapply it with one click.
- A small dot next to the topbar title shows when a filter is narrowing what you see.
Click a source pill to isolate it; All shows everything. Per source you can Start (load its full history) and Download it.

Live stats show total, visible, error and warning counts. The favicon shows the unread count while the tab is in the background. If the server is redeployed while a tab is open, a banner asks you to refresh.
Dark, Light and Solarized. Theme, wrap, timestamps, colors, filters, sidebar state and source selection are saved in the browser's localStorage.
--ui-highlight enables keyword highlighting from a preset (default: preset/default.json):
{
"words": { "err": "color: red;" },
"lines": { "err": "font-weight: bold;" }
}Built-in presets: default, npmlog, python. Pass your own with --ui-highlight-preset <path>. You can also add up to five colored keyword highlighters in the sidebar at runtime.
