Log Analyzer Pro – Instantly open multi-GB logs in VS Code using Rust

Summary: Log Analyzer Pro is a VS Code extension that uses a Rust backend and memory-mapped I/O to open gigabyte-sized log files instantly without freezing the editor. It supports virtual scrolling, regex search, smart filtering, and live tail updates, enabling efficient log analysis within the IDE.

What it does

The extension avoids loading entire files into memory by using a Rust sidecar with memory-mapped I/O and builds an instant line index for lag-free navigation. It renders only visible lines via virtual scrolling and provides regex search, filtering, and live "tail -f" updates.

Who it's for

It is designed for developers and engineers who need to analyze large log files directly in VS Code without performance issues.

Why it matters

It eliminates editor freezes and high RAM usage when opening large logs, replacing the need to switch to terminal tools for log inspection.
