LogStack: right-click a log line to see its call stack

Click a log line in VS Code and jump straight to the call stack that produced it

Problem

A HN Show HN introduces a VS Code extension that lets you right-click any log line to see its call stack. The underlying pain: when debugging production issues, developers get a log line but don't know which code path emitted it, so they grep the message and manually reconstruct the call chain, which is very slow in large codebases.

Solution

A VS Code extension that parses logs in the current file or pasted input, identifies log statements and context, and uses static analysis or a runtime agent to show likely call stacks and trigger paths. Right-click to jump to source, highlight the call chain, and save an investigation as a shareable note.

Users

Backend developers, production debuggers, teams maintaining large codebases

MVP

Log line detection and context menu; static-analysis-based call path display; jump to source; call chain highlighting; investigation note export

Revenue

Free basics; Pro one-time $29 with multi-language, runtime tracing, and team-shared notes

Why now

The VS Code extension ecosystem is mature and log debugging is a frequent pain, but existing tools focus on search rather than call chain reconstruction; an indie dev can differentiate quickly with LSP and static analysis
