What is the best widget to install on a donation site?

Question

Donations

I have a website that is used by an average of 300-400 people a day. Since I spend time on it and, albeit a little, but money, I thought that I wanted to connect the opportunity to support developers.

But I don't know which widget to use for this. It is desirable that it be possible to enter the amount or choose from predefined options, click on the payment and go to the payment service.

There are a lot of services on the Internet that allow you to connect payment to your site, but some of them involve some legal issues and business registration, others do not allow you to embed the widget on the site, and others simply with negative reviews. This is not a payment for the goods, but a voluntary donation.

Advise any good service for such purposes, please.
