Built for Real-World Refactoring

Say goodbye to expanding text trees level by level. Understand your blast radius in seconds.

Blast Radius Analysis

Instantly see how many API routes, queue workers, and cron jobs depend on a service function before you modify or delete it.

Instant Shortcut

Place cursor on any function name and press ⌥T (macOS) or Alt+T (Windows/Linux) to visualize incoming callers immediately.

Smart Noise Filters

Toggle unit test files off with a single click (Alt+Shift+T) or filter strictly to entry-point HTTP routes only.

1-Click Mermaid Export

Generate clean Mermaid diagram markdown ready to paste into GitHub Pull Request descriptions for instant reviewer architecture context.

100% Local-First & Private

Zero external network calls, zero telemetry, no third-party cloud. Everything runs privately inside your local VS Code editor.

Interactive Navigation

Pan, zoom, fit view, and click any node in the directed graph to jump directly to that exact line of source code.

Case Study

Detect Blast Radius Across Auth & Cron Jobs

When refactoring shared utilities like discordLogger.error(), Mewra Pounce instantly reveals all 4 entry points (2 Authentication API routes and 2 Scheduled Cron Jobs) across 27 callers before you introduce breaking changes.
