Getting stuck paying 35 USD yearly when you could have payed less than 9 with the same provider for a better known tld like ".com"
You can't find good free website names. So in our case, we took .io domain, which costs us $50/year. That's very expensive, but we have branded website name on .io
and when we bought .io 2.5 years we spent several days looking for a cheaper option. For dev tool having some shitty website name or provider is suck
