Django Built in Validators - Client side or Server side Validation?

[eqmunir]

Hello. On my form(forms.Form), I apply some built in validators (e.g EmailValidator), from django.core.validators. Are these classed as client-side or server-side validation?

So do I need to do the same validation again using the clean method for server side validation. I know client side validation is not secure and server side validation is recommended. Thanks.

server-side validation

They’re server-side. They run in Python, on your webserver.
