Comparison of browser engines

This article provides general information for browser engines, especially actively-developed ones.[lower-alpha 1]

Some of these engines have shared origins. For example, the WebKit engine was created by forking the KHTML engine in 2001.[1] Then, in 2013, a modified version of WebKit was officially forked as the Blink engine.[2]

General information

Engine Status[lower-alpha 1] Steward License Embedded in

Notes

  1. ↑ 1.0 1.1 Active status means that new Web standards continue to be added to the engine. However, Maintained status can be as minimal as ensuring the engine code still compiles. Discontinued is when the engine code is abandoned.
  2. ↑ Internet Explorer continues to receive security updates,[7] which means Trident is still maintained.
  3. ↑ NetSurf does not support HTML5 or other recent Web standards,[11] which means it cannot work properly at YouTube, Gmail, and many other popular websites. Thus it does not merit Active status per this article's criteria.
