The record

Product: massCode is a free, open source local-first desktop workspace for code snippets, Markdown notes, HTTP requests, calculations, and developer utilities.
Snippet library: The Code space organizes reusable snippets across projects and languages with folders, search, and an editor.
Notes: Notes supports Markdown documents, task status and due dates, a notes graph, mindmaps, and presentation mode.
HTTP client: The HTTP space supports collections, environments, scripts, tests, sequential runs, GraphQL, and WebSocket.
Imports: The HTTP workspace can import requests from OpenAPI, Postman, or Bruno.
AI integrations: The AI assistant can connect to OpenAI, Anthropic, Gemini, DeepSeek, Mistral, or xAI using the user's API key, or to local models through Ollama or LM Studio; cloud API usage is billed by the provider.
MCP: A coding agent can connect through MCP to search, read, and save snippets, notes, and HTTP requests.
Browser clipper: Clipper saves selected code, page text, and links from the browser into Code, Notes, or HTTP, with Chrome, Firefox, and Safari builds documented.
Local storage: Snippets and notes are stored locally as plain Markdown files in a vault that users can read, edit, move, and back up outside massCode.
Security limitation: Vault files are plain text, and the maker advises against storing secrets in synced, shared, or Git-committed vaults; HTTP secret variable values are stored outside the vault and encrypted on the device.
Sync: There is no built-in cloud account or proprietary sync service; users can sync the vault folder with iCloud Drive, Dropbox, Google Drive, Syncthing, or Git.
Privacy: The maker says massCode collects no telemetry and tracks no users.
Supported platforms: The download page offers macOS builds for Apple Silicon and Intel, Windows builds, and a Linux download for Ubuntu.
License and maker: The project is AGPL v3 and its site credits Anton Reshetov, with copyright dating from 2019.
