Northstar is a minimalist web browser written from scratch in C. One window, one page, one process — about 160,000 lines of original C, small enough for one person to read and audit end-to-end. It carries no upstream browser engine: no Gecko, no WebKit, no Blink. It is free software under the GNU General Public License, version 3 or later, and it runs on Linux, macOS and Windows — on Windows from the Microsoft Store.
Northstar Browser version 1.0.12 released! A sunny ark comic on about:start, a classic Mozilla-style toolbar with address-bar suggestions, relayout and repaint that only redo what changed, popovers per the HTML standard, the Microsoft Store package, an 8 MB engine stack, and a build on Fabrice Bellard’s original QuickJS
Is opera not a good alternative?
No, they’ve been bought out by a super shady company years ago. They’re also chromium now. The original Opera team partially moved to create Vivaldi, also Chromium.
Opera is also based on chrome. If your goal is to not use Google chrome then yes. Servo is not based on chrome or firefox. It is completely its own thing.
