FAQPage Schema
How do I automate screenshot capture for macOS windows and iOS simulators?▼

Automate screenshot capture by invoking a cross-backend script targeting browser pages, iOS simulators, Ghostty sessions, and macOS windows. It returns the absolute output path of the saved PNG file and identifies the backend used.

Can I capture terminal UI screenshots from a Ghostty or tmux session?▼

Yes, you can capture terminal UI screenshots from Ghostty or tmux sessions. The tool identifies the active session backend and saves the visual output as a PNG file to a deterministic absolute path.

What is the best way to get deterministic output paths for automated UI testing screenshots?▼

Use a screenshot automation primitive that returns the absolute output path and the backend used. This enables deterministic workflows for UI validation, visual regression testing, and automated documentation.

Do I need Swift and xcrun to capture screenshots across different macOS backends?▼

Yes, Swift, xcrun, and screencapture are required dependencies. They provide the underlying system-level execution environment needed to capture windows, iOS simulators, and terminal sessions.

Does this screenshot tool save images in formats other than PNG?▼

No, the screenshot capture tool saves images in PNG format by default. It applies this format across all supported backends including web, mobile, terminal UIs, and native macOS applications.
