Ngrok Opiniões 

Si necesitas probar en localhost con https es el mejor servicio sin dudaaaaaaaa!

To be honest and frank, I love Ngrok and I'd rate it 4 stars. It is free, no limits, you can host on it whatever you want. I use Ngrok to self-host Stoat. However, the thing that bothers me is that Ngrok doesn't keep you 24/7 cloud online, instead you should have a computer always on and has powershell, for that thing I hope Ngrok adds the feature that you can control it cloudly and always online WITHOUT requiring a device.

Their support is a joke, first of all they only have one email id to contact support, in that if you send an email that will take anywhere between 7-10 days, if you have anything important running, ngrok is not the one to pick, even if you wait for that long they dont give a damn, when i had an issue i clearly documented everything that they need to solve the issue but what i got in return is along the lines of "can be fixed but i wont help you because you said we are late". i will proceed to complain on consumer forums about this. i did not pay for pro subscription to get talked down.

Billing is a nightmare. I kept getting billed tunnels I had no idea where they came from. No ability to restrict tunnels set-up, so expect unexpected items in your monthly bills. Only way to stop the extra costs is to delete and even that's broken. Extend past the free tier at your peril.

They are supporting scammers. Scammers are using their servers to scam peoples. They create phishing page and send links via sms.

Even after complaint ngrok is not taking any action against scammers. They just care about payments from scammer.

Unclear billing process, advertised as per month but then charged per year.
Unclear feature distribution between account levels, seemingly basic features locked behind higher tiers.
Poor quality installation documentation for linux, specifically ARM and ARM64.
