User Reviews

Dave C.

fly.io offers stable hosting for my custom Discord bot through a Docker container.The free plan, as noted in other reviews, doesn’t exist but is instead a pay-as-you-go plan which waves invoices smaller than $5.00, so make sure you know what you’re doing and set your fly.toml file accordingly.Furthermore, seemless integration with GitHub and a nice UX overall. Thanks for waiving invoices smaller than $5.00, too!

Signed up for a free trial and got DAILY email reminders asking me to add my credit card to their website when I only made an account.No unsubscribe button, or way to reply to the email.Seems very predatory in my opinion. I've never had a SaaS email me this aggressively for just signing up for their service.
