Every Fly.io frustration, solved.
Fly.io problem
"Fly.io has a steep learning curve"
Machines API, fly.toml, volumes, regions — Fly.io is powerful but requires significant DevOps knowledge.

Even with EU regions, Fly.io is subject to US jurisdiction and the CLOUD Act.

Common Questions
FAQ
Which is better for EU hosting, Coolify or Fly.io?
Neither Coolify nor Fly.io is EU-native. Both are US-headquartered and route the majority of traffic through US data centers. For genuine EU data residency, an EU-registered platform like Runsite is the safer choice — a Frankfurt (eu-central) region under EU jurisdiction, no transatlantic transfers, no CLOUD Act exposure.
Which has the better free tier, Coolify or Fly.io?
Free tiers on both Coolify and Fly.io change frequently and often include compute or bandwidth caps that expire after a trial period. If a permanent free tier matters, evaluate the current terms on each provider before committing.
Is Coolify or Fly.io GDPR-compliant?
Both can be configured to support GDPR-compliant workloads via Data Processing Agreements (DPAs), but as US entities they remain subject to the CLOUD Act. For workloads where US jurisdiction is a hard blocker, an EU-headquartered provider is required.
What is the cheapest way to deploy a side project — Coolify or Fly.io?
Pricing on both Coolify and Fly.io can scale unpredictably with traffic or build minutes. Hard spending caps are not available on either platform. Predictable monthly pricing with usage caps is a differentiator to look for elsewhere.
