Browser with proxy for each tab?

Question

Browsers

You need a browser in which you can set a different proxy for each tab. I found a couple of solutions, but very expensive - $50 to $1,000 per month.

Is there really no open source or free solutions? Maybe Brave has that option?

Answer 1

Run many copies of the browser ...
If for Windows, then for example sandbox. Make you a sandbox. Run at least 20 browsers with different settings
