Keycap gives coding agents a screen to inspect
Keycap is a Mac capture app presented as a way for coding agents to inspect windows, record screen sessions, and make demo videos.
- For
- Mac developers using Claude Code, Codex, or MCP agents
- Worth noticing
- The demo shows a workflow from Safari capture to localhost checks, 60-fps recording, and exports in 16:9, 1:1, and 9:16 formats.
Field notes
The illustrated workflow pairs a reference site with a local page: the agent captures the reference, makes a change, and captures again to check it. The page says captures include text and address information, including text scrolled out of view, and describes search across saved captures as a Pro feature. Its example shows an MP4 recording and highlight exports in landscape, square, and vertical formats; the page does not establish that these features are available now.
