During my tests after initial installation it didn't prove to be very stable, unfortunately. But then again, it hasn't been advertised as being stable and is still very much work in progress.

This is a port of C based Netsurf ( https://www.netsurf-browser.org/ ) whose modular core allows it to be ported to other toolkits. According to the Netsuf website there are frontends for Amiga, Atari, BeOS, Framebuffer, GTK, RiscOS, and even Windows. Debian contains a GTK+ and a framebuffer variant of it in its repositories.

Websurf is thus not a new application written from the gound up in Objective-C but rather a port of Netsurf to the GNUstep GUI framework.
