Lepton vs massCode

Lepton is a free desktop code snippet manager that uses GitHub Gist for storage and syncing. It supports unlimited public and secret snippets, unlimited tags, and language groups, plus editing for Markdown and Jupyter Notebook snippets. Search can match filenames, languages, descriptions, tags, IDs, and downloaded snippet contents. Searching all snippet contents globally requires enabling `snippet.downloadAll` before syncing. Lepton supports GitHub Enterprise and lets users sign in with GitHub OAuth or a GitHub personal access token with the `gist` scope. The project says there is no separate sync service: data is stored locally in the app or remotely in GitHub Gist. Packaged builds use Electron safeStorage for cached tokens when available, with a plaintext-file fallback if it is unavailable. Settings in `.leptonrc` include themes, editor options, proxy, shortcuts, notifications, and language. Desktop releases are available for macOS, Windows, and Linux, including AppImage and Snap packages for Linux. The project is MIT-licensed. The free plan costs nothing.

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.
