Best open-source browsers in 2026
Short answer
The best open-source browser in 2026 is Brave, followed by Firefox and Zen Browser.
This list uses one fixed set of weights. The quiz ranks all 57 browsers for your own devices and priorities — 12 questions.
Open source means anyone can read the code, audit what the browser sends home, and fork it if the project goes wrong — which is how half the browsers on this site came to exist. Only fully open-source browsers qualify; partially open ones like Vivaldi are left out.

How this list is ranked
Each browser's 0–3 scores are multiplied by these weights and added up — the quiz's arithmetic with the answers fixed: Site compatibility ×2.75 · Low maintenance ×1.5 · Tracking protection ×1 · Extension ecosystem ×1. Rules: only fully open-source browsers. Equal scores go to the browser that does better on the most heavily weighted criterion. Full methodology.
