Runs based on the Trident engine. Still looks interesting nevertheless: https://www.radsix.com/
Nessie is an extremely simple web browser for Windows, best used as a secondary browser. It was inspired by other minimal web browsers such as Netsurf or Dillo, but aims for better compatibility with the modern web, and higher security.
It is one of the few remaining browsers based on the Trident layout engine. (You might have a strong urge to stop reading right here - don't!)
Its feature set is intentionally limited to the bare essentials, to minimize both distractions and attack vectors. It is a good option if you are looking for a fast, casual and low-resource browser, or need to use legacy websites requiring an IE-compatible web browser.
Note that Nessie has no extensions, no tabs, and no toolbars. On the surface, it could be described as just a "webview with an address bar". Read below to find out how it is much more than that.
