macss - Handpicked Mac apps, with the pricing spelled out

macss is a hand-curated directory of macOS apps. Every entry is written from scratch, not copied from the developer's landing page, so you get a straight answer on what it does. The part most lists skip is pricing. macss tells you whether an app is free, freemium or paid, and how you pay: one-time, subscription or licence. Open source apps link to their repo and licence, and anything no longer maintained gets flagged. Categories include menu bar, window management, notch and developer tools.
