IBrowse is an MUI-based web browser for the Amiga range of computers, and was a rewritten follow-on to Amiga Mosaic, one of the first web browsers for the Amiga Computer. IBrowse was originally developed for a company called Omnipresence, now defunct. The original author has since continued development of IBrowse.

IBrowse supports HTML, and some HTML 4, JavaScript, frames, SSL, and various other standards.

IBrowse was one of the first browsers to include tabbed browsing as early as 1999. This was introduced in IBrowse²

A limited OEM version of IBrowse is included with the new 4.0 version of AmigaOS.

IBrowse v2.4, the latest version of the software, is not currently available for sale to new customers, although existing v2.x users can download and install the demo version over their existing installation in order to access all functionality.
