Soffit

A native Mac workspace for markdown.

Tile any folder. Edit. Preview. Sketch. All in one window.

Why

Markdown lives in folders. Folders should live in panes.

Drag a tab. Split it. Edit a PRD beside a mermaid diagram beside a Figma frame beside a terminal running claude.

No vault. No plugin manager. No syncing service. Your files stay where you put them.

For the post-Obsidian crowd who'd rather not run Electron.

Install

Download Soffit-0.3.0.dmg → drag to Applications → right-click Open the first time.

Requires macOS 14. Apple Silicon preferred. Intel will do.

Or build from source — see the Quickstart.

In the box

• Markdown editor — Preview, Source, Split. Real GFM rendering. Tables. Code. Lists. The works.
• Search everything — ⌘P jumps to any file. ⌘⇧F searches every word in the workspace. [[wiki-links]] and a tag browser stitch your notes together.
• Mermaid diagrams — render .mmd files inline. No internet required.
• Web embeds — Figma frames, localhost dashboards, anything WKWebView loads.
• Embedded terminal — drop into claude, git, vim. Whatever you'd put in iTerm.
• Tile anything — drag any tab onto any pane. A compass picks the side.
• It remembers — quit, reopen. Panes, tabs, modes: exactly where you left them.
• Multi-window — ⌘N for a new window. Each one has its own panes; one workspace, one index, no conflict.
