Simtec Limited

Simtec Limited is a privately held company based in Devon, England.

HttpWatch was first released in April 2002 and was the first tool to provide seamless monitoring of HTTPS traffic from Internet Explorer. Support for Firefox was added in 2008 and an iOS app was approved for the Apple App Store in 2013.

The widely used HTTP Archive Format (HAR) was initially designed by the HttpWatch and Firebug teams as an open, portable JSON file format based on the HttpWatch XML file export. It is now supported by many browsers and HTTP sniffing tools making it easier to exchange HTTP log files.
