Show HN: Right-click any log line to see its call stack in VS Code

No guessing. No grepping. No tab-switching. Just click and see the flow.

Click any frame to jump straight to that point in your source code.

LogCallStack │ ├─ Line 42 · Thread main · 3 frame(s) ← click to return to log line │ ├─ ● handleConnection() connection.cpp:88 ← the method that logged it ├─ ○ readSocket() network.cpp:210 ← what called it └─ ○ pollEvents() event_loop.cpp:201 ← the entry point

Local Variables ├─ fd = 12 ├─ timeout = 5000 └─ retries = 3

Click a frame → jump to that exact line in source

Local Variables panel → shows variable values extracted from the log message alongside declarations found in source

Stack header → click to return to the original log line at any time

Features

Zero setup — open a log file, right-click a line, done.

Works offline — no AI, no cloud, no telemetry. Pure local static analysis.

Fast — parallel source search across your entire workspace, results in under a second even on large codebases.

Progressive results — frames appear as they are found; you are never staring at a blank panel.

Custom log formats — built-in wizard to configure any format not auto-detected.

10+ languages and frameworks supported out of the box.

Supported Languages & Frameworks

Auto-detection requires zero configuration:

Not seeing your format? Use Configure Log Format… to define a custom regex pattern.

The right-click menu appears only in log files — never in source code files — so it stays out of the way.
