@nha Keechma has more built in features and a somewhat different approach. Regarding bidi, I don’t think it would be too hard to add a support for it in Keechma, the only thing I’m not sure about is how to implement reverse url generation -> given a map {:page "article" :id "123"} - how can you generate a url with bidi? In Keechma, the idea is that this is done automatically by whatever is the closest matching pattern, so you never think about how the URL looks in the UI layer, you just pass the data you want to represent in the URK
