About spacecake

Spacecake is an open-source desktop app. It helps developers use Claude Code better. It combines a writing area like Notion with a special terminal. This makes one place to plan, code, and run things. It works on macOS and Linux. It helps teams work with AI by keeping track of their projects.

Key Features

WYSIWYG Markdown Editor.

Spacecake offers a special editor. It mixes simple markdown writing with visual features. It hides markdown symbols when you're not editing. This makes text look clean and formatted. It’s a lot like Notion. This editor keeps markdown files easy to move and track. But it also gives you a rich-text editing experience. You can use GitHub-flavored markdown. This lets you make code blocks with color highlights, checklists, and diagrams.

Integrated Terminal with Ghostty.

Spacecake doesn't make you switch apps. It has Ghostty built right in. Ghostty is a fast terminal emulator. This means you can run command-line tools. You can also run Claude Code. And you can manage your deployments here too. No need to jump back and forth. You can change the terminal size. Or you can open and close it with quick keys. This makes the interface fit your work. Ghostty works fast on both macOS and Linux. So your editing stays smooth.

Real-Time Context Window and Usage Tracking.

There’s a status bar that shows Claude Code metrics. It tells you how much context is being used. And it shows estimated API costs. This helps you make smart choices about your prompts. If context gets full, you can fix your specs. Or you can start a new Claude Code session. This clears the context. The tracking shows if you're saving tokens
