massCode vs Opengist

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.

Opengist is a free, open-source pastebin that you host yourself, with Git as its storage and workflow. Every snippet is a Git repository: users can create snippets with a plain Git push, or clone and push over HTTP or SSH. Visibility can be public, unlisted, or private, and snippets may contain multiple files, binary files, and images, with ZIP downloads available. Users can browse revision history, compare changes with diffs, and search full text, code, and metadata. Rendering includes syntax highlighting for hundreds of languages plus Markdown, Mermaid, LaTeX, CSV, and media files. Login options include GitHub, GitLab, Gitea, OIDC, and LDAP; TOTP and WebAuthn are listed for account security. Deployment options are a single binary, Docker, or Kubernetes with SQLite, PostgreSQL, or MySQL. A REST API, embeds, JSON retrieval, topics, likes, and forks are also provided.
