Why choose NetSurf?
- Efficiency lies at the heart of the NetSurf engine, allowing it to outwit the heavyweights of the web browser world. The NetSurf team continue to squeeze more speed out of their code.
- Interface innovation
- Simple to use and easy to grasp, NetSurf significantly raised the bar for user interface design on the RISC OS platform. Designed carefully by RISC OS users and developers to integrate well with the desktop, NetSurf is seen as the benchmark for future applications. NetSurf pioneered the concept of web page thumbnailing, offering an intuitive graphical tree-like view of visited web sites.
- Lean requirements
- From a modern monster PC to a humble 30MHz ARM 6 computer with 16MB of RAM, the web browser will keep you surfing the web whatever your system. Originally written for computer hardware normally found in PDAs, cable TV boxes, mobile phones and other hand-held gadgets, NetSurf is compact and low maintenance by design.
- NetSurf can be built for a number of modern computer platforms 'out of the box'. Written in C, with portability in mind, NetSurf is developed by programmers from a wide range of computing backgrounds, ensuring it remains available for as many users as possible.
- Standards compliant
- Despite a myriad of standards to support, NetSurf makes surfing the web enjoyable and stress-free by striving for complete standards compliancy. As an actively developed project, NetSurf aims to stay abreast of new and upcoming web technologies.

- LibCSS performance boost 02 Dec 2013
- A significant optimisation has been made to LibCSS's selection engine performance. This is the code that works out which CSS rules apply to DOM elements, and calculates their computed styles. Recent development builds of NetSurf include this improvement.
- Static analysis of NetSurf's codebase 22 Nov 2013
- NetSurf and several of our libraries have recently been added to the Coverity Scan service for open-source projects. It has enabled us to identify and fix quite a few bugs over a very short period. We also have the Clang static analyser set up as part of our CI system. For more information on the utilisation of static analysis by the NetSurf project, take a look at this article.
- Summary of recent development 16 Oct 2013
- Some of the recent changes made to NetSurf have included a rewritten core treeview widget. It fixes bugs, provides a nicer look & feel, and yields an improvement to startup time. The Global History, Hotlist (Bookmarks), Cookie Manager, and SSL Certificate Inspection treeviews have all been rewritten with the new treeview. Another recent change is the addition of undo and redo support to NetSurf's textarea widget.
