What are stock images with a free commercial license?

Question

Design

The same freepik, for example, requires its mention on products, plus pictures should not be the main element, only a secondary one.

Answer 1

Pixabay, Unsplash, Pexels - these three are usually enough.
If not, I go into the Google Images settings, where you can specify the type of license.

Answer 2

What free stocks do you use to find icons, photos, and interface elements?
