GuineaBrowser
A tiny, private web browser with a Kids Mode. A lightweight browser focused on safety, control and efficiency, with no tracking at all. Kids Mode blocks inappropriate content, Safe Mode limits tracking and blocks ads, and RAM Saving Mode caps memory at 200 MB.
What it does
Safety switches that actually work.
Kids Mode
Blocks inappropriate content, so a younger sibling can browse on their own.
Safe Mode
Limits tracking and turns on the ad blocker. It also supports routing through a VPN bridge.
RAM Saving Mode
Keeps memory under 200 MB without crashing, even with several tabs.
History you control
Every visit is listed, and you can delete any of it.
Standalone
Version 1.1.5 needs no external DLLs. Install it and it runs.
Settings panel
Every safety and privacy switch lives in one place.
Memory
Twenty-three times lighter.
Version 1.1.5 was the biggest update GuineaBrowser has had: a redesigned homepage, a polished interface, a standalone build and the settings panel. It is also the version where the source went public on GitHub.
Relative memory use from Adrian's own testing, as stated in the GuineaBrowser README. RAM Saving Mode also sets a hard cap of 200 MB.
