How Fly.io scored 70/100
6 weighted criteria, each scored out of 10 and published with its reasoning. Featured placements never move a score.
Deal Strength
3.0 /10There is no exclusive coupon or founder discount on Fly.io through this listing, so the offer is simply the standard account. New organizations get a short free trial (roughly 2 VM-hours or 7 days) rather than the generous free allowance older accounts once enjoyed, so treat the real value as the low pay-as-you-go rates, not a headline deal.
Value for Money
9.0 /10Fly.io is priced aggressively for global edge hosting: a shared-cpu-1x machine with 256MB runs about $2.02/month, billed per second so idle apps cost almost nothing, and reserved compute blocks cut rates by 40%. Persistent volumes are $0.15/GB per month and North America/Europe egress is just $0.02/GB, undercutting most managed-container rivals for small, always-on workloads.
Capability
9.0 /10Fly.io runs your code in Firecracker microVMs, the same hardware-isolated tech behind AWS Lambda, with anycast load balancing, private WireGuard networking, persistent volumes, and Managed Postgres built in. It deploys full-stack apps and containers to 35 regions from one CLI, covering most global-app needs, though GPU machines are being retired, so it's no longer the pick for heavy AI inference.
Time to Value
8.0 /10Most developers ship a live app in minutes: point Fly at a Dockerfile, run fly launch and fly deploy, and it builds, provisions a machine, and serves it on a global anycast address. Multi-region scaling, custom Postgres clusters, and private networking add setup time, but a single-region container is genuinely running the same afternoon.
Trust & Reliability
7.0 /10Fly.io is a well-established platform trusted by thousands of developers and teams running production workloads across its 35 owned regions, with tiered support from a $29/month plan up to enterprise and HIPAA-eligible options. It publishes no headline uptime SLA on standard accounts, and edge platforms can see region-level hiccups, so mission-critical apps should design for multi-region failover.
Flexibility & Exit
8.0 /10Billing is pure pay-as-you-go with per-second metering, no seat minimums, and no long-term commitment, so you can scale to zero or shut an app down and simply stop paying. Because everything runs from standard Docker images, workloads stay portable to any other container host, keeping lock-in low even though full data export is a manual step.
About Fly.io
Quick answer
Fly.io is an application platform that deploys Docker containers to a global edge of Firecracker VMs starting at shared-cpu prices around $1.94/month. It's a strong fit for any HTTP/TCP app you can containerize, and the free tier (3 shared VMs, 1 GB Postgres, 3 GB volumes, 160 GB outbound transfer) is enough to host a real side project at zero cost.
Most "edge" platforms only run your static site or a thin function at the edge. Fly.io does something different: it runs your full Docker container — your Express, Rails, Django, Go, or Elixir app — on Firecracker microVMs in 30+ cities worldwide, with built-in load balancing, Postgres, Redis, and S3-compatible object storage. For solo devs and small teams who don't want to babysit AWS, it's one of the most compelling app hosts in 2026.
What is Fly.io?
Fly.io is a public cloud built around Fly Machines — lightweight Firecracker microVMs that boot in roughly 250 ms and can be launched, stopped, snapshotted, or duplicated via API. Instead of choosing one region like a traditional VPS, you declare where your app should run (e.g., nrt, fra, gru, syd) and Fly deploys containers to those regions, balances traffic between them, and gives you a single Anycast IP that routes users to the nearest healthy machine.
Founded in 2017 by Kurt Mackey and now headquartered in Chicago, Fly.io started as a CDN for SSH and has evolved into a full application platform. It owns and operates its own hardware in 30+ regions across North America, South America, Europe, Africa, Asia, and Oceania, and it was one of the first providers to ship a Tigris-powered S3-compatible object store natively integrated with the platform.
Key features
Fly Machines (Firecracker VMs)
Sub-second cold starts, suspend/resume APIs, and per-machine vertical scaling. Start at 256 MB RAM and scale up to large dedicated-cpu instances for the same app.
Anycast global load balancing
One IP routes to the nearest healthy region automatically. Add or remove regions with a single fly regions add command.
Built-in Postgres
Managed, replicated Fly Postgres clusters with point-in-time recovery, read replicas, and a 1 GB free tier for development.
Upstash Redis & Tigris S3
Native Redis (Upstash for Redis) and S3-compatible object storage (Tigris) — no third-party account needed.
Docker-first deploys
Push a Dockerfile (or use a buildpack) and fly deploy ships it. Zero-downtime rolling releases, automatic HTTPS, and free cert management.
Private networking & WireGuard
Apps on Fly share a 6PN private network, and you can connect your laptop via WireGuard to debug production as if you were inside the VPC.
Fly.io pricing in 2026
Fly.io's pricing is split into three buckets: compute (Machines), storage (volumes + object storage), and bandwidth. The free tier is genuinely usable, not just a 7-day trial.
Paid plans (verify current pricing on fly.io/docs/pricing):
- Shared CPU from ~$1.94/month (shared-cpu-1x, 256 MB) up to ~$7.78/month (shared-cpu-8x, 8 GB).
- Dedicated CPU from ~$5.94/month (1 vCPU / 2 GB) up to multi-vCPU machines.
- Memory-optimized instances for caches and in-memory data stores.
- Bandwidth: $0.02/GB outbound beyond the 160 GB free pool (ingress is free).
- Persistent volumes: $0.15/GB-month for SSD.
- Fly Postgres: Development (free, 1 GB), Launch (~$7.94/mo, 10 GB), Production tiers per vCPU/RAM.
- Tigris object storage: Free up to 5 GB, then usage-based.
Tip: shared-cpu machines share a physical core with other tenants and are great for low-traffic apps, APIs, and workers. Switch to dedicated-cpu once your p99 latency or CPU-bound workloads demand it.

Getting started
4 steps. The last one is the part most people skip.
- 1
Open Fly.io through the link on this page
It carries our referral tag. The price you pay is identical either way, and it never changes the score on this page.
- 2
Compare the tiers against what you actually use
The pricing table on this page lists what each plan includes. Match it to real usage rather than the tier the vendor highlights.
- 3
Start on the smallest plan that fits
Most vendors let you move up mid-cycle and bill the difference, so starting low costs you nothing but starting high does.
- 4
Check the renewal terms before you commit
Note the renewal date and the rate it reverts to, so the second invoice is not a surprise. Annual plans are usually cheaper per month but harder to exit.
Where Fly.io wins and loses
What works
- 30+ deployment regions with anycast routing delivers applications close to users globally with no CDN needed
- Machines API enables any Docker container to run as a serverless function with per-second billing
- Fly Postgres is a distributed, multi-region PostgreSQL cluster with automatic failover between regions
- Multi-region deployment is first-class — app.toml config controls region placement without infrastructure code
What doesn't
- Pay-as-you-go pricing requires budget monitoring — resource costs accumulate without hard limits
- More configuration complexity than Render or Railway for initial setup and networking
- Fly Postgres is developer-managed (not fully managed) — operational responsibility remains with the user
- Documentation quality varies — some edge cases and configurations require community forum research
The bottom line
Fly.io is one of the sharpest app-deployment platforms for developers who want their containers running close to users worldwide: push a Dockerfile, run fly deploy, and hardware-isolated microVMs boot in seconds across 35 regions. Per-second pay-as-you-go pricing is genuinely cheap, but the once-generous free tier is gone and there's no exclusive discount here, which is what keeps it a solid Buy rather than a slam dunk.
Fly.io uses pay-as-you-go pricing billed per second, with no monthly plan fee. The smallest shared-cpu-1x machine (256MB RAM) costs about $2.02/month if left running, extra RAM runs roughly $5/GB per 30 days, and persistent storage volumes are $0.15/GB per month. Outbound bandwidth starts at $0.02/GB in North America and Europe.
No, Fly.io no longer offers a permanent free tier for new accounts. The old free allowance of three shared VMs and 160GB of bandwidth was deprecated in late 2024, so new organizations are pay-as-you-go only. New users instead get a short free trial, roughly two VM-hours or seven days, to test deployments before any charges begin.
Fly.io is worth it for developers who want containers running close to users globally without stitching together multiple cloud consoles. Per-second billing makes small, always-on apps cheap, and deploying is as simple as pushing a Dockerfile. It's less ideal if you need a free hosting tier, a formal uptime SLA, or GPU machines, which are being retired.
Fly.io gives you more control and global reach than Heroku or Render by running your app as Firecracker microVMs across 35 regions with anycast routing, rather than a single-region dyno. It's typically cheaper at scale thanks to per-second billing, but it's more hands-on: you work at the container and CLI level instead of a fully managed push-to-deploy button.
The biggest limitation is the lack of a permanent free tier and no published uptime SLA on standard accounts, which pushes hobbyists and reliability-sensitive teams to plan carefully. Fly.io is also winding down GPU machines after August, so it's no longer a fit for heavy AI or LLM inference workloads that need dedicated accelerators.
You deploy on Fly.io using its flyctl command-line tool: run fly launch in your project to detect the app and generate a fly.toml config, then fly deploy to build the Docker image and boot it as a microVM on a global anycast address. Add Managed Postgres, volumes, or extra regions with a few more commands as your app grows.
