Fuwa keeps the window you need on top of other apps on your Mac. Keep a reference image, document, or tutorial visible while you work, without switching back and forth. The pinned view lets clicks pass through to the app underneath.
109 seconds · 4K · 60 fps · English female narration. Draft a shot list from a brief, keep tutorial settings in view, compare references, and write design notes beside an image.

Download Fuwa-<version>.zip from GitHub Releases, extract it, and move Fuwa.app to /Applications. Every public package has a matching .sha256 file:
cd ~/Downloads
shasum -a 256 -c "Fuwa-<version>.zip.sha256"Replace <version> with the actual version number. Versions v0.1.4 and earlier need one manual upgrade to v0.1.5 or later. After that, select Check for Updates in Fuwa Settings. Fuwa accepts only its fixed GitHub feed and packages verified by the embedded public key; verification failure never falls back to unsigned installation.
The macOS package uses the project's maintained local signing identity, not Apple Developer ID signing or notarization. If macOS blocks it, verify the source and SHA-256 and follow Apple's instructions, rather than weakening system security.
Fuwa uses Swift, SwiftUI/AppKit, ScreenCaptureKit, and Sparkle.
git clone https://github.com/yuxino/fuwa.git
cd fuwa
./scripts/setup-local-signing.sh
./scripts/install-app.shFuwa is now maintained for macOS only. Windows development and releases have ended. Existing Windows release files and Git history remain available as unsupported archives; future macOS releases will not provide Windows installers or update feeds.
Fuwa displays a mirror, not a change to another app's real window level. It does not bypass operating-system security boundaries or protected-content restrictions.
