SnippetsLab
What SnippetsLab is
SnippetsLab is a free macOS app for developers who want a personal library of code snippets and notes. Content can be arranged with nested folders, tags, smart groups, shortcuts, and multiple tabs inside a snippet. Syntax highlighting supports more than 600 languages and text formats, while automatic detection handles 50 popular languages. Markdown features include side-by-side previews, Mermaid diagrams, MathJax formulas, code blocks, and customizable CSS themes. Full-text fuzzy search, smart filters, intelligent ranking, a menu-bar assistant, and Quick Actions help users locate and access saved material. SnippetsLab connects with Alfred, Raycast, macOS Services, GitHub Gists, a command-line tool, and an MCP server for compatible AI agents. It can import from Quiver, CodeBox, GitHub Gists, JSON, and plain text, and export libraries as JSON, XML, or text files. iCloud Sync synchronizes a library across Macs signed into the same Apple ID, and automatic backups are retained at several intervals. The app is available only through the Mac App Store, requires macOS 14.6 or later, and supports Apple Silicon and Intel. Its Free plan costs nothing, with no ads, in-app purchases, or subscriptions.
