fly.ioReviews of fly.io

We experienced zero friction migrating our containerized workloads over to Fly.io. It is refreshing to see an infrastructure provider that isn't just an API wrapper over AWS; they run hardware-virtualized KVM containers that spin up fast enough to handle incoming HTTP requests natively. The built-in private mesh networking works beautifully over WireGuard tunnels out of the box, completely eliminating the need for bloated Terraform configurations for intra-cluster auth. To be fair, their official documentation can be quite sparse and minimalist, occasionally forcing you to hunt through their community forums to resolve specific edge-case routing issues. However, their new Sprites sandboxing feature executes environment checkpointing in under a second, and the CLI-driven deployment is rock solid.

I have a similar opinion to Srikanth's review: some users who rate Fly.io poorly may not have enough technical expertise to fully understand how the platform works. I have been using Fly.io for over a year, and my experience has been consistently positive. The platform is simple, clean, and user-friendly. Pricing is transparent, so I always know what I am paying for, and deployments through flyctl are straightforward and reliable. I have also used AWS extensively. While AWS offers more services and flexibility, it is significantly more complex. One of Fly.io's biggest strengths is that it provides a much simpler and more developer-friendly experience, with a clean interface and straightforward deployment workflow. For many projects, that simplicity is a major advantage rather than a limitation. Fly.io is especially well suited for personal projects, learning, and small applications. If you understand how to optimize your resources and deployments, it is possible to run projects at very low cost. In my experience, the platform provides excellent value, and I appreciate how developer-focused it is. I also want to support Fly.io because I believe they are building something valuable for developers. My experience with the platform has been excellent, and I hope they continue improving and growing in the years ahead. Overall, Fly.io has been a reliable and enjoyable platform to use, and I would happily recommend it to other developers. I would especially recommend it to junior developers and anyone who wants to learn modern deployment workflows without the complexity of larger cloud platforms. The fast and straightforward deployment process makes it easy to focus on building and learning rather than spending hours on infrastructure configuration.

THIS IS THE WORST COMPANY THEY LITERALLY SHUT DOWN MY ACCOUNT FOR WHATVER REASON I HAVE 500 IN CREDITS AND SCREWED UP MY ENTIRE GROWING BUSINES I WILL BE SUING THEM IF NOT RESPONDING SOON THESE GUYS ARE BAD

BE CAREFULL flyploy, fly.io ARE A BIG SCAM. NEVER GIVE YOUR CREDIT CARD INFORMATION : NO WAY BACK, THEY CHARGE YOU EVERY MONTH WITH NO POSSIBILITY TO CANCEL IT

I signed up and tried to set up an app. My attempts were not successful. I never successfully deployed an app once. Yet I was being charged for database clusters that were not getting any operations on them. I had an abandoned attempt to use them and gave up only to have multiple charge attempts. I'm glad I secured my payments from actually going through which saved me from losing money.

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.

In july 19, suddenly I got a mail from bank. Fly.io tried to deduct 25$. I instantly sent a mail to there support mail. They said I was activated Prepared Credit! But I never do it. Today I get another mail, they try to charge 747$. After july I don't log into fly.io and my deploy was failed those time. Now when I login after seen this mail. I'm surprise! 22 days ago a project was deployed! But I do not deploy anything. Please stay safe. Never trust fly.io for billing issues. They will suddenly charge from your card. They have various excuse.

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!
