Snapline — Code Screenshots

Turn code into beautiful, shareable images in one click. Select code, press ⌘⌥S / Ctrl+Alt+S, and get a polished snapshot in your editor's own theme — ready for Twitter/X, LinkedIn, docs, slides or a PR.

A fast, actively maintained alternative to CodeSnap and Polacode.

Features

• Your exact theme — colors come straight from your editor, so the image matches what you see.
• One click — select code → Snapline: Snap Code (context menu, editor title button, or ⌘⌥S). No selection snaps the whole file.
• Beautiful by default — gradient backgrounds, window controls, file title, soft shadow, adjustable padding.
• Line numbers that start at the real line number.
• Smart dedent — nested code is shifted to the left edge automatically.
• Save PNG (2× resolution) or copy the image straight to your clipboard.
• Doesn't clobber your clipboard — whatever you had copied is restored after a snap.
• Settings are remembered between snaps.
