ghostty is fast and gorgeous, which makes it a great terminal to demo in. capncap records it as a proper shareable video — and for Terminal.app and iTerm2 it goes further, capturing the commands you run as copyable text.
1. install capncap
get it free from the mac app store (macOS 15+) and sign in with your Apple ID.
2. pick the ghostty window and record
select your ghostty window in capncap, optionally turn on your camera for narration, and hit record. stop, and the share link is ready — viewers pick their own layout (pip, side-by-side, screen only).
copyable commands
when you record Terminal.app or iTerm2, capncap also captures every command you run, with its timestamp. the shared page shows them as chips: click to copy, or click the time to jump the video there. ghostty support for this is next — ghostty's applescript doesn't expose terminal text yet, so for command capture use Terminal.app or iTerm2 today.
tips for a clean demo
bump the font size (cmd+plus) so the video reads well at any size. a 16:9-ish window shape fills the player.
agents can do this too
capncap ships a CLI and an MCP server, so an AI agent (like Claude Code) can start a recording of its own terminal work and hand you the share link when it's done: capncap record ghostty … capncap stop.
