Slimjet report card
Very good · out of 4.0 · graded Nov 13, 2026
Best for a free Chromium browser with built-in extras
Slimjet is a freeware Chromium browser with an ad blocker, proxy switcher, form filler and video downloader. The Mac build on its download page is version 45, while Windows and Linux are at 51, and there is no phone version.
Who Slimjet is for

- Works for downloading streaming video from inside the browser

- Watch out: the ad-blocking and privacy claims are the vendor's own
- Tight if you want a paid support route: the company asks only for donations

Keep Slimjet, or make your own?
Keep it
Slimjet is free, so making your own would save you nothing.
And it is not the kind of software a weekend replaces.
What you could make
- Ad and tracker blocking: an app builder makes this well.
What you could not
- A web browser.
- Apps for macOS, Windows and Linux that stay in step with each other.
What this rests on. Slimjet’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.
