massCode vs Snippet Box

massCode is a free, open-source, local-first desktop workspace for code snippets, Markdown notes, HTTP requests, calculations, and developer utilities. Its Code space organizes reusable snippets with folders, search, and an editor. Notes supports Markdown documents, task status and due dates, a notes graph, mindmaps, and presentation mode. The HTTP workspace handles collections, environments, scripts, tests, sequential runs, GraphQL, and WebSocket, and imports requests from OpenAPI, Postman, or Bruno. A browser clipper can save selected code, page text, and links into Code, Notes, or HTTP. Snippets and notes are plain Markdown files in a local vault that users can read, edit, move, or back up outside the app. There is no built-in cloud account or proprietary sync, though the vault folder can be synced with external services. AI connections can use provider API keys or local models; cloud API use is billed by the provider. Downloads include macOS, Windows, and Ubuntu Linux builds, with browser extensions for Chrome, Firefox, and Safari.

Snippet Box is a free, MIT-licensed self-hosted application for creating, editing, browsing, and managing code snippets in different languages. Its built-in editor handles snippet authoring, while syntax highlighting and detail views help users read code and documentation. Markdown support allows notes or simple documentation alongside snippets. A tagged library supports filtering, and users can pin important or favorite snippets to the home screen. Search covers snippet titles and descriptions, with language and tag filters that can be combined in one query. The project documents Docker deployment and a non-Docker route that runs the built server with Node.js. The listed backend uses Node.js, TypeScript, Express.js, Sequelize, and SQLite; the frontend uses React, TypeScript, and Bootstrap. A Docker example mounts a host data directory at /app/data. Docker build instructions include Linux and ARM targets, including arm/v7 and arm64. The listed plan costs nothing, and no free trial is listed.
