We landed in 2020 and we don't have any complete, native-like, cross-platform GUI toolkit (if we skip Qt and GTK). In last years a lot projects have appeared, which were trying to compete in GUI toolkit market share. All of them had its scope limited, however they brought quite fresh look on declarative programming interface [0][1], superb 2D rendering pipeline [2][3], ease of embedding [4] and adaption to low-power devices [5] but none of them is "complete".
