Tkhtml is a discontinued open-source browser engine written in C using the Tk widget toolkit.

[1][2] It was used primarily by the Html Viewer 3 (Hv3) minimalist web browser.

Version 1 was written using the XF application builder, but because of functionality reasons this part was rewritten.

[2] In 2006, it was announced that a public build of Tkhtml Alpha 10 had passed the Acid2 test.

The TkinterWeb package, for example, can be used to embed Tkhtml in Python applications.
