LogLens — open multi-gigabyte log files instantly

Stop fighting your log files. LogLens opens huge logs that the built-in editor chokes on — multi-GB files load in a snap with indexed, virtualized scrolling. No "file too large" wall, no freezing, no waiting.

Features

• Huge files, instantly. A streaming index means the file is never loaded whole — a 10 GB log opens as fast as 10 MB, with smooth scrolling through millions of lines.
• Live tail. Follow a log as it grows, with auto-scroll — like tail -f, inside your editor.
• Filter in and out. Keep only the lines that match (text or /regex/), and hide the noise with a separate exclude filter (like grep -v). Combine both to slice signal from noise.
• Level highlighting. Errors, warnings, and traces are color-coded out of the box, so problems jump off the screen.
• ANSI-aware. Colored console output renders correctly instead of showing as escape-code garbage.
• Multi-line stack traces stay intact and readable.

Plus live sources

• Tail Kubernetes logs — LogLens: Tail Kubernetes Logs (Command Palette). Pick a namespace and pods; LogLens streams and merges them live in the same fast viewer. Requires kubectl on your PATH.
• Webhook inspector — LogLens: Start Webhook Inspector. Captures inbound HTTP requests on a local port, shows headers/query/body live, and replays any request to a target of your choice.
• OTel trace viewer — LogLens: Start OTel Trace Receiver. Runs a local OpenTelemetry (OTLP/HTTP) receiver and renders incoming traces as a span waterfall.

⭐ LogLens Pro — coming soon

A paid Pro tier is on the way for developers who live in their logs: cross-file trace merge (follow one request across multiple logs), SQL log queries, JSON field querying & pretty-print, regex-capture columns, an error-density timeline, tail alerts, bookmarks with notes, custom highlight rules, saved filter views, and redaction-on-copy.

Everything listed above stays free. Pro is already available for JetBrains IDEs — the VS Code edition is in progress.

Getting started

Just open any .log file — LogLens takes over as the editor and renders it in the fast viewer. For the live tools (Kubernetes, webhooks, traces), open the Command Palette and type "LogLens".
