The report card
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.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | A | Freeware with no registration, and donations are optional, so under 60% of this category's cheapest quarter. |
| Free plan and trial | A | The whole browser is free to use with no registration and nothing locked behind a plan. |
| Features | C | Ad blocker, proxy switcher, form filler, video download and screenshots, but the ad-blocking and privacy claims are the vendor's own. |
| Ease of use | B | No rating on record. You install a Chromium browser and it works, with the extras already in the toolbar. |
| Platforms and integrations | C | Windows, macOS and Linux only. No mobile versions are listed, and no integrations. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.

Keep it, or make your own?
Whether this is something you could build for yourself with an AI app builder, and what you would give up.
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.
