OmniWeb
OmniWeb is a legacy Mac web browser from The Omni Group, built for browsing and managing web pages with advanced tab and workspace features.
What is OmniWeb?
OmniWeb is a Mac web browser created by The Omni Group for people who want a desktop browser with extensive control over tabs, page organization, and browsing behavior. It was developed as an alternative to mainstream browsers and is known for user-facing features such as browser workspaces, site preferences, and flexible tab handling. Users commonly encountered it as a native macOS browser for reading websites, organizing groups of pages, and customizing how pages open and display. OmniWeb is no longer actively maintained, so it is mainly relevant on older Mac setups, for compatibility testing, or for users who specifically want this legacy browser. As a native Mac app, it fits best in classic macOS workflows rather than modern cross-platform browser ecosystems.

Safety overview
Status: Mostly safe
OmniWeb is legitimate software from The Omni Group, but it is a legacy browser that is no longer actively maintained. For a web browser, the main practical concern is that older software may not receive current compatibility or security updates for modern websites and web standards. It should be used carefully if you plan to sign in to important accounts or browse sensitive sites. If you keep it installed, use it mainly for older workflows, testing, or non-sensitive browsing.
Recommendation: Keep OmniWeb only if you intentionally use it for legacy browsing, compatibility checks, or older Mac workflows. If you do not use it, removing it is reasonable and should only affect access to the browser itself and its saved browsing data.
