WaifuX feels like a real passion project that has grown into something genuinely useful. The idea is simple to understand but ambitious in practice: one macOS app for ACG wallpapers, dynamic backgrounds, Wallpaper Engine-style content, anime video sources, favorites, local library management, and multi-display setups. The project does a good job presenting that value quickly. The README has screenshots, multilingual docs, multiple install options, system requirements, a license, and careful disclaimers around third-party content, which makes the repo feel much more mature than a typical hobby app.

What stands out most is the rule-based source system. Separating source rules from the app itself is a smart design choice because these content sources can change often, and shipping a full app update for every site change would be painful. The recent release history also shows that the maintainer is actively fixing real user problems, including dynamic wallpaper support, signing/dependency issues, memory work, multi-display improvements, and parsing fixes. The codebase also looks thoughtfully separated into areas like Services, Views, ViewModels, Models, Rules, and DesignSystem, which gives the impression that the project has been allowed to grow without becoming completely tangled.

My main suggestions are small but important. First, the README seems to have a compatibility mismatch: one section says Apple Silicon only, while another says both Apple Silicon and Intel Macs are supported. Clearing that up would save users confusion before they install. Second, I’d love to see a clearer “build from source” section with Xcode version, macOS version, dependencies, test commands, and any signing limitations. Since the open issues include performance, audio, baking progress, and feedback-channel questions, a short troubleshooting or roadmap section would also help users understand what is known, what is planned, and where useful contributions are welcome.

Overall, WaifuX already has a lot going for it: a clear audience, active maintenance, a polished user-facing README, and a technical design that makes sense for a fast-changing content ecosystem. With a bit more contributor documentation and clearer compatibility notes, it could become much easier for new users and outside contributors to trust and participate in the project.
