StackTop is a free Chrome add-on developed by Travis J. It falls under the category of browsers and specifically the subcategory of add-ons & tools.

With StackTop, users can modify the top bar in their Chrome browser. The add-on allows users to make various changes to the top bar, such as changing the name of the "Documentation" link to "Docs" and removing the beta subscript from the Documentation name. Users can also remove the jobs link and color the background of the top bar to a grey (#ccc) color.

In addition, StackTop enables users to set the top bar to position: relative, keeping it at the top of the browser. The add-on also removes the review link and allows the top bar dropdowns to hover open and remain open when navigating to other dropdowns for a short period of time.
