## What it is
massCode is a free, open-source, local-first desktop developer workspace built with Electron and Vue. It combines a code snippet library, Markdown notes, an HTTP API client, a math notebook, Excalidraw-style drawings, and small developer utilities in one offline app that stores data as plain files.

## Use cases
- manage a reusable code snippet library across projects and languages
- write markdown notes and a personal knowledge base with folders and tags
- send and organize HTTP API requests without leaving the workspace
- import collections from Postman, Bruno, or OpenAPI
- do quick calculations like currency and unit conversion in a math notebook
- sketch diagrams and wireframes on an Excalidraw canvas
- convert, encode, hash, and generate data with built-in dev tools
- keep all developer notes and snippets offline in plain files

## When to avoid
- you need real-time team collaboration or cloud sync of snippets and notes
- you need a full-featured API client with advanced testing, scripting, or CI integration
- you want a web-based or mobile tool rather than a desktop app
- you need enterprise features like SSO or access control
