Run containers close to users on Fly Machines. No free plan for new accounts, only a trial of up to 7 days.
Sniffed 21d ago7 day free trial Card required#hosting#containers#docker#paas#edge#postgres#flyctl
Docker containers in regions around the world, with a trial in place of a free plan. Fly.io runs your Docker containers as Machines in regions around the world, deployed with its flyctl command line tool. It also sells volumes, Managed Postgres and Fly Kubernetes. New organizations get no free tier. They get a trial of up to 2 hours of Machine runtime or 7 days, whichever ends first, with no card to start and a card required afterward. The smallest always-on Machine, a shared-cpu-1x with 256 MB, lists at $2.19 for 30 days, and outbound traffic in North America and Europe is $0.02 per GB. The pricing page's example of a small web app plus Managed Postgres comes to about $43.67 a month. Trustpilot shows 2.8 from 20 reviews, Product Hunt 5.0 from 28 and G2 4.7 from 3. Reviewers like Dockerfile deploys and response times. Complaints center on surprise charges and deployment errors.

👍 Good boy
+Product Hunt shows 5.0 from 28 reviews, all from founders who mention easy deployment and a developer-friendly feel. Some mention the free tier, which new accounts no longer get.
+A Trustpilot reviewer from 2023 summed it up as writing a Dockerfile and deploying it, with full control and no cold starts. They also praised the simple monitoring and wished for a managed Postgres, which Fly now sells from $38 a month.
+A June 2026 Trustpilot reviewer migrated containerized workloads with no friction and said the private mesh networking works over WireGuard out of the box. They called the command line deployment solid.
+A May 2026 Trustpilot reviewer with over a year on Fly.io called the pricing transparent and the deploys through flyctl straightforward, and said small projects can run at very low cost if you tune resources.
+A 2025 Trustpilot reviewer hosts a Discord bot in a Docker container and called it stable. They said invoices under $5 are waived, which is that reviewer's statement, so confirm it on your own billing page.
+A 2023 Trustpilot reviewer who was unhappy overall still called the HTTP response latency really good.
+The pricing page lists per-Machine rates and a worked example: a small web app plus Managed Postgres comes to about $43.67 a month.
+Several network costs are zero: shared IPv4 and IPv6, inbound traffic and the first 10 single-hostname SSL certificates.
👎 Watch out
−There is no free tier for new organizations. Trustpilot reviewers say plainly that the free plan does not exist and that you pay as you go, and one reviewer noted a trial prompt followed by daily emails asking for a card.
−Billing surprises recur on Trustpilot: an unrequested dedicated IP charge (June 2025), an unrequested $29 email support charge that was refunded (2024), surprise charges that were refunded (2024), charges for database clusters on an app that never deployed (January 2026) and a disputed $747 charge (September 2025). Fly.io's side of these is not in the reviews.
−Stability complaints appear. A July 2025 reviewer called it not production ready, citing deployment errors, random 500 errors on the dashboard and unexplained deploy delays. A 2023 reviewer lost the contents of a WordPress volume after an outage.
−A 2023 reviewer described deployments failing twice in three days with unhelpful error messages and said other users were reporting the same in the forums. Even a positive 2024 reviewer mentioned occasional downtime.
−An April 2026 reviewer said Fly.io shut down their account while they held $500 in credits. This is one unverified account.
−Documentation gets mixed reviews. A June 2026 reviewer who liked the platform called the docs sparse and said they had to search community forums for edge-case routing problems.
−Costs add up outside Machines. Volumes are billed at $0.15 per GB a month even when detached, stopped Machine root filesystems cost $0.15 per GB a month, and egress in Africa and India is $0.12 per GB.
−Trustpilot shows 2.8 from 20 reviews on an unclaimed profile that has not asked customers for reviews, so it may not represent typical users. Many of the low scores are about billing.
The catch
Fly.io has no free tier for new organizations. New accounts get a trial of up to 2 hours of Machine runtime or 7 days, whichever ends first. You do not need a card to start, but you need one after the trial. Organizations on plans that Fly.io discontinued in October 2024 keep their old allowances.
After the trial you pay for what you run. The smallest always-on Machine, a shared-cpu-1x with 256 MB, lists at $2.19 for 30 days. The 512 MB size is $3.69, 1 GB is $6.70, a shared-cpu-2x with 2 GB is $13.39 and a performance-1x with 2 GB is $33. Extra RAM is $6 per GB a month. Machines are only part of the bill. Volumes cost $0.15 per GB a month even when detached, snapshots cost $0.08 per GB after the first 10 GB, a dedicated IPv4 is $2 a month, and egress is $0.02 per GB in North America and Europe, $0.04 in Asia Pacific, Oceania and South America and $0.12 in Africa and India.
Trustpilot reviewers describe surprise charges, some of which were refunded, so set up billing alerts and check what is running. One reviewer said invoices under $5 are waived. That is a reviewer's statement, not something I found on the pricing page. I found no commercial-use statement for the trial, so that field is unknown.
