TL;DR
Nogic is a free Visual Studio Code extension that generates interactive diagrams of a codebase, including class diagrams and call graphs. The extension (version 0.0.14) indexes projects with user permission and provides boards, quick search, and auto-sync features.
What happened
Nogic has published a Visual Studio Code extension that builds interactive visualizations of a project's structure. The tool presents a unified hierarchical graph of files, classes and functions, and supports dedicated views such as class diagrams and call graphs. Users can create custom "boards" to focus on parts of a codebase, add files or folders to a board from the Explorer context menu, and open the visualizer from the Command Palette. The extension will index the workspace when the visualizer is opened if the user grants permission, and it includes an auto-sync capability so code changes are reflected in the diagrams. Version metadata in the marketplace notes release 0.0.14 (dated 2025-11-24) and a last updated timestamp of 2026-01-13; the listing shows it is free and identifies Nogic as the publisher.
Why it matters
- Visual representations can help developers understand architecture and relationships in unfamiliar or large codebases faster than reading files alone.
- Class diagrams and call graphs make dependency and inheritance patterns easier to spot, aiding refactors and debugging.
- Boards and quick search let teams isolate subsystems or onboarding tasks without navigating the entire project tree.
- Auto-sync reduces the maintenance burden of keeping diagrams current as the code changes.
