LogLens is a fast large-file log viewer that lives in your editor — indexed scrolling, live tail, level highlighting, and text/regex filtering. No "file too large." No frozen IDE. No falling back to the terminal.
That 4 GB request dump. The gigabyte of stack traces from last night's incident. You double-click it and the IDE spins, warns "file too large," or just hangs — so you drop into a terminal, grep blind, and lose all the context your editor was supposed to give you. LogLens opens it — all of it — in a second.
A streaming index means the file is never loaded whole. 10 GB opens as fast as 10 MB, with smooth scrolling through millions of lines.
Follow a log as it grows, with auto-scroll — tail -f, without leaving your IDE.
Filter by log level or by text/regex and jump straight to the lines that matter — your position is never lost.
Errors, warnings, and traces are color-coded out of the box, so problems jump off the screen.
Colored console output renders correctly instead of showing up as escape-code garbage.
Multi-line stack traces stay grouped and readable — no scrolling through fragmented noise.
Most viewers load the entire file into memory — which is why they choke. LogLens does the opposite: it streams the file once to index where every line begins, then renders only the handful of lines actually on your screen. Memory stays flat whether the file is 10 MB or 10 GB, and scrolling stays instant because there's never more than a screenful in play.
LogLens processes everything locally. Your log contents are never uploaded, collected, or seen by Veryation. What's in your logs stays on your computer.
One plugin, every JetBrains IDE: IntelliJ IDEA, PyCharm, WebStorm, GoLand, Rider, CLion, PhpStorm, RubyMine, DataGrip, Android Studio — and more. Also available for Visual Studio Code.
LogLens is growing into the telemetry surface for your editor. Already in the VS Code build, with more on the way:
Stream and merge logs from multiple pods, right in your editor.
A local OTLP receiver and a span waterfall.
Capture, inspect, and replay inbound webhooks.
Multi-gigabyte, comfortably. The index and windowed reads are designed to scale well beyond typical log sizes.
No. It indexes line offsets in a single streaming pass and only ever holds the visible window in memory.
Every JetBrains IDE (it depends only on the platform, not any language), plus Visual Studio Code.
Yes — the core viewer, tail, level colors, and filtering are free. A Pro tier with power features is coming.
No. All processing happens locally on your machine. Your log contents never leave your computer.
