One Does Not Simply

Iqiyyi- A good way to watch anime (Also includes korean drama and other east-asian Tv shows) and if you have a potato device, don't use this, it uses to much memory processor power and ram

Bilibili is a better version of Iqiyi but it has a bug that the caption randomly disappears

You can watch anime in youtube but it's pirated

In netflix, you can only watch old anime or anime that is not that popular unlike MHA and boruto

AnimeLab and Funimation can be a good candidate but it can only serve on some areas on the globe

Gogoanimation is what I you can use if AnimeLab and Funimation does not work in your location. But is has more ads

All what I mention are free, unless you don't want ads or you want a VIP or Premium access

Use simplyaweeb.com it basically has every anime the only bad thing is that you can’t really browse through genres you have to figure out what you want to watch or ask for recommendations
