ReUI vs ssych
ReUI and ssych both add to shadcn/ui and both install through the shadcn CLI. ReUI, made by Keenthemes, is a large kit for app screens with a strong data grid. ssych is a smaller library built around trading, crypto and AI operator screens. Here is how they compare.

Short answer
Pick ReUI for admin and SaaS apps that need a lot of blocks and a serious data grid. Pick ssych when the product is a trading or crypto screen and needs an order book, a depth chart or candles with volume. Both install through the shadcn CLI, so they work in one project.
