Here you have different front-ends for propietary services.

Replace "twitter.com" with "nitter.esmailelbob.xyz" for every URL.

For convenience, you can try Libredirect for Firefox, and IceRaven from FDroid as a Firefox alternative for Android.

Thanks! That's a nice resource, some of those I did not yet know about

If you install Libredirect and head to the settings, you can use the Esmailelbob instances for lots of services. I suggest such instances because these are the ones which worked better.
