it's not a search engine, but a proxy, you get your results from multiple sources. i'm currently using it as my main place to search stuff and it works, sometimes there are some quirks (i could improve my config maybe) but it works, i've tried searxng years ago and it was a mess in comparison. keep in mind degoog it's written in js mostly so it's a bit heavy but it has more features and stuff. if you want absolute minimum 4get works very well.
