Otter Browser review (2026): is it any good?
Open-source Qt browser that revives the classic Opera 12 interface
Otter Browser report card
Very good · out of 4.0 · graded Nov 13, 2026
Best for a customizable browser in the Opera 12 style
Otter is a free, open-source browser in C++ and Qt that recreates the classic Opera 12 interface. Development is slow, with about seven commits a week from one author, and the site names no macOS build.
Who Otter Browser is for
- Fits if you miss the classic Opera 12 layout
- Makes sense if you want a light, tweakable desktop browser
Who Otter Browser is not for
- Skip it if you use a Mac or a phone, as macOS is not named
- Not for you if you want quick fixes: recent weekly reports show about seven commits by one author
- Watch out: the weekly reports show 254 open issues, including 7 bugs
- Too light for modern web apps if you rely on the newest standards

Keep Otter Browser, or make your own?
Keep it
Otter Browser is free, so making your own would save you nothing.
And it is not the kind of software a weekend replaces.
What you could not
- A web browser.
- A real app for Windows and Linux. Something home-made would be a web page.
What this rests on. Otter Browser’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
