In plain English

Lepton is a free desktop application for managing code snippets. It runs on macOS, Windows, and Linux. Rather than storing snippets in its own database, it uses GitHub Gist as the backend, which means your snippets live in your GitHub account and sync automatically. If you already use GitHub Gist, Lepton gives you a dedicated desktop client to work with those snippets more comfortably than through the GitHub website. The app organizes snippets by programming language automatically and lets you add unlimited tags to each one. You can have as many public or secret snippets as you want, with secret snippets being visible only to you through your GitHub account. Beyond code, Lepton also renders Markdown files and Jupyter Notebook files directly, so it works as a lightweight viewer for those formats too. The interface includes a search bar that can be triggered with Shift+Space, an immersive mode that hides the surrounding chrome to focus on the snippet content, and a dashboard view. There are keyboard shortcuts for creating, editing, deleting, and syncing snippets. The app can be customized through a configuration file called .leptonrc in your home directory, covering themes, editor settings, proxy configuration, and custom shortcuts. Both a light and dark theme are built in. Installation is straightforward: download a release from GitHub, or on macOS install via Homebrew, or on Linux via the Snap Store. For GitHub Enterprise users, the README notes there is a configuration option to point the app at a self-hosted GitHub instance. Lepton is built using Electron, a framework that lets web technologies run as a desktop application. The frontend uses React and Redux. The app is free and licensed under the MIT license.
