Fly.io deploys your app to edge locations worldwide using Firecracker micro-VMs. Powerful, but the pricing is complex and the learning curve is steep. InstaPods keeps it simple with flat pricing and real servers.

| SSH Access | Yes (fly ssh console) | Full SSH + web terminal |
| Custom Domains | Yes (manual cert config) | Yes (automatic setup) |
| HTTPS | Automated SSL | Automated Let's Encrypt |
| Deploy Method | flyctl CLI (Dockerfile required) | CLI, Git push, GitHub |
| Edge Locations | 30+ regions worldwide | EU region (expanding) |
| Complexity | Steep learning curve (fly.toml, Machines API) | One command to deploy |
A fair look at their strengths.
Fly.io runs your app in 30+ regions worldwide. For latency-sensitive applications serving a global audience, edge deployment is a genuine advantage.
Each app runs in a real micro-VM (not a container), providing strong isolation. The same technology that powers AWS Lambda under the hood.
Fly offers up to 3 shared-cpu-1x VMs with 256MB RAM for free. Enough to experiment with small projects without paying anything.
Limitations to consider before choosing.
Fly bills for CPU, RAM, bandwidth, volumes, and IP addresses separately. The pricing page has a calculator for a reason. Estimating monthly costs requires serious math.
Deploying on Fly means learning fly.toml configuration, the Machines API, flyctl commands, and often writing a Dockerfile. It is developer-friendly, but not beginner-friendly.
Fly has gone through multiple architecture changes (Nomad to Machines). Long-running users have had to migrate apps multiple times. The platform moves fast, sometimes too fast.
Where we do things differently.
InstaPods detects your app type and deploys it. No Dockerfile, no fly.toml, no Machines API. Run `instapods deploy my-app` and you are live.
Fly.io bills for CPU-seconds, RAM-hours, and bandwidth. InstaPods charges a flat rate. $3/mo means $3/mo regardless of traffic or uptime.
Fly.io is built for global scale. InstaPods is built for getting your app online quickly and keeping it running affordably. Different tools for different needs.
Running a small app with 1 vCPU, 1GB RAM, and a 1GB volume
Get your app online in under a minute. Real servers, flat pricing, no surprises.
