SlimBrowser is a tabbed multiple-site web browser from FlashPeak, Inc., an Austin, Texas-based company.

[2] It incorporates a large collection of features like built-in popup killer, skinned window frame, form filler, site group, quick-search, auto login, hidden sites, built-in commands and scripting, online translation, script error suppression, blacklist/whitelist filtering, and URL Alias.

SlimBrowser was one of the twelve browser choices offered to European Economic Area users of Microsoft Windows in 2010.

[3] Since V6.0, SlimBrowser has adopted a multi-process architecture to improve stability and eliminate performance restrictions associated with traditional single-process browsers.

FlashPeak also makes the cross-platform browser SlimJet which uses Chromium (Blink engine[4]).
