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
