Lepton

Lepton is a macOS‑only application that lets users store, organize, and retrieve code snippets by synchronizing them with GitHub Gist. It presents each gist with a formatted description that can include a title and a set of custom tags, and it groups snippets by language or user‑defined tags for easier navigation. The interface offers instant search triggered by a keyboard shortcut, a dark theme, and an immersive mode that hides distractions while editing.

The tool renders Markdown and Jupyter notebooks directly within the app, allowing users to take rich‑text notes or view data‑science notebooks without leaving the manager. Users authenticate with GitHub either via credentials or a personal access token, and the application relies on GitHub’s API to detect the language of each gist, with an option to override detection through a comment directive.

Lepton is open source and distributed under a free license, with no payment or donation required. It targets developers, data scientists, and anyone who maintains reusable code fragments and wants a lightweight, tag‑driven workflow integrated with their existing GitHub Gist storage.
