The NetSurf project is developing a document browser for the World Wide Web. It was started in 2002 on the RISC OS platform and has support for numerous operating systems and graphical toolkits.

NetSurf is very modular and built from many component libraries which provide functionality from GIF image format decoding (libnsgif) to HTML document object model handling (libdom).

NetSurf browser is open source and is licensed under the GPLv2 (with OpenSSL exception). Many of the supporting libraries are under a MIT licence.
