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. - **Value for money: A.** Free software under GPL v3 with no paid plan, so under 60% of this category's cheapest quarter. - **Free plan and trial: A.** The whole browser is free and open source, with no caps or paid tier. - **Features: C.** A customizable, lightweight browser for power users, with the basics but a small team behind it. - **Ease of use: B.** No rating on record. You install a binary or AppImage and use it, with options to tune if you want. - **Platforms and integrations: C.** Windows and Linux are listed.

And it is not the kind of software a weekend replaces. - You could not: A web browser. - You could not: A real app for Windows and Linux. Something home-made would be a web page.
