Sciter is an engine for building user interfaces in desktop applications, distributed as a DLL, just over 5MB in size. It is positioned as a competitor to Electron and Qt.
This engine is used by many large companies for their products. These are mainly anti-virus programs (ESET, Dr.Web, Symantec, Avast, etc.), but there are others, including Samsung, VMWare, Evernote, and so on.
