Louvre is less modular but handles a lot of tedious tasks behind the scenes, providing a simple API (the enjoyable/creative part I’d say) without sacrificing much flexibility. On the other hand, Wlroots is excellent and highly modular, which is good, but it also means it places all the responsibility on you. You must invest time to fully understand each protocol and implement many tedious tasks yourself, which naturally takes quite some time. Additionally, Louvre is multi-threaded, as seen in the benchmark results in the repository, resulting in higher and more stable FPS compared to single-threaded designs when rendering complex scenes.
