As of sizes ... For Sciter Quark ( https://quark.sciter.com https://quark.sciter.com ) I've measured size of minimal "Hello World". - Electron: 50 MB on disk, 200 MB of RAM and at least 2 processes running. - QT: 5 MB (and 30 MB if + QtWebKit) and ~70 MB (200 MB if QtWebKit) of RAM. - Sciter Quark (standalone Sciter executable): 5 MB on disk, 32 MB in RAM. That includes HTML/CSS UI, JS engine, NodeJS alike runtime. Out of the box Sciter works on same platforms as Electron.
