Fly.io vs Railway
Fly.io vs Railway compared for European indie developers and small startups. Pricing, EU jurisdiction, GDPR posture, and why Runsite (an EU-registered PaaS in Frankfurt) is worth a look.
Fly.io vs Railway: quick answer
Fly.io and Railway both offer Git-push deploy workflows, but they differ where it counts. Railway starts around $5/mo. Fly.io and Railway are both US-headquartered, so neither escapes US jurisdiction or the CLOUD Act, and neither runs EU-native infrastructure or offers hard spending caps. For European teams that need GDPR-compliant hosting in Frankfurt with predictable EUR billing and a permanent free tier, Runsite is the EU-native alternative to both.

Fly.io problem
"Usage-based billing is unpredictable"
Per-second VM billing and bandwidth charges make it hard to predict monthly costs.
Runsite solution
Fixed plans + hard caps

What about Railway?
Railway is developer-friendly but US-based. Runsite offers the same DX with EU data centers and GDPR compliance.

Common Railway frustrations. Sound familiar?
Every Railway frustration, solved.
Railway problem
"Railway only has US servers"
All Railway deployments run in US-West-1. European users experience higher latency.
Runsite solution
EU-only Frankfurt region
Deploy to Frankfurt (eu-central) with EU data residency. Sub-20ms latency for European users.
Railway problem
"$5 free trial runs out fast"
Railway's trial credit depletes quickly. After that, you're on usage-based billing with no free option.
Runsite solution
Permanent free tier
No trial. No credit card. Build and deploy side projects forever at zero cost.
Railway problem
"No built-in object storage"
Railway offers persistent volumes but no S3-compatible object storage. You need external providers.
Runsite solution
S3-compatible storage included
Store files, assets, and backups with built-in S3-compatible object storage. No third-party setup needed.

// pricing, side by side
Fly.io vs Railway: what each actually costs
No permanent free tier. A limited trial gives one-time credit; the Hobby plan is $5/mo including $5 of usage.
Railway has a great developer experience and fair per-second metering, but the lack of a permanent free tier and fully usage-based billing make costs unpredictable, exactly the problem a hard spending cap solves.

How Fly.io and Railway each compare to Runsite
Fly.io vs Runsite
The thing that trips people up on Fly.io is the complexity, not the capability. The fly.toml configuration, Machines API, volume management, and region-aware routing all require significant learning before you ship. Per-second billing across multiple dimensions (CPU, RAM, bandwidth, IPs) makes cost prediction difficult, and because Fly.io is a US company, even its EU regions leave your account and metadata under US jurisdiction.
None of that is a knock on the engineering. Firecracker microVMs, global edge deployment, WireGuard-based private networking, and a powerful Machines API give you fine-grained control over where and how your containers run. For developers who want infrastructure-level flexibility with some PaaS convenience, Fly.io delivers.
Runsite makes the opposite trade, swapping low-level control for simplicity: connect GitHub, pick a region, deploy. Fixed monthly pricing with hard spending caps and full EU legal compliance. If you want Docker hosting in Europe without learning a new infrastructure API, and you value predictable costs over edge computing flexibility, Runsite removes the operational overhead that Fly.io requires.
Railway vs Runsite
You probably picked Railway for its DX, and it earns that reputation. The dashboard is clean, deployments are fast, and the usage-based pricing model is straightforward once you understand it. As a modern PaaS without legacy baggage, it is a strong contender.
Where it leaves you exposed is geography. Railway runs exclusively in US-West-1, with no European regions, which means higher latency for your EU users and no option for EU data residency. The $5 trial credit also depletes quickly, dropping you onto pure usage-based billing with no free fallback. Runsite runs in Frankfurt (eu-central), a fully EU-jurisdictional region, is incorporated as an EU legal entity, and includes built-in S3-compatible object storage that Railway lacks.
If you are building products for European markets, or you want a permanent free tier for side projects instead of a trial credit, Runsite is worth a look. The developer experience is comparable, but the infrastructure is EU-native from the ground up.

Common Questions
FAQ
Which is better for EU hosting, Fly.io or Railway?
Neither Fly.io nor Railway is EU-native. Both are US-headquartered and route most traffic through US regions, with EU availability that is usually limited or gated behind higher tiers. Even when you can select a European region, the parent company stays subject to the US CLOUD Act, which can compel disclosure of EU customer data. For genuine EU data residency, an EU-registered platform is the safer choice: Runsite runs exclusively in Frankfurt (eu-central) under EU jurisdiction, with no transatlantic transfers and no CLOUD Act exposure — the kind of guarantee neither US provider can make.
Which has the better free tier, Fly.io or Railway?
Free tiers on both Fly.io and Railway change frequently and tend to share the same catch: compute that sleeps after inactivity, bandwidth or build-minute caps, or trial credits that expire after a fixed window. They are fine for quick experiments but rarely sustainable for an always-on hobby project. If a permanent free tier matters, read the current terms carefully. Limits are often buried in the pricing footnotes. Runsite takes the opposite approach: a free tier with no credit card and no expiry, designed to keep small projects online indefinitely rather than nudging you onto a paid plan.
Is Fly.io or Railway GDPR-compliant?
Both Fly.io and Railway can be configured to support GDPR-compliant workloads through a signed Data Processing Agreement (DPA) and EU region selection where available. However, as US-incorporated entities they remain subject to the US CLOUD Act regardless of where the data physically sits, which is a documented sticking point for European compliance and DPO review. For workloads where US jurisdiction is a hard blocker (public-sector, healthcare, or privacy-sensitive consumer apps), an EU-headquartered provider removes the ambiguity entirely. Runsite is EU-registered with data kept inside the EU, so GDPR posture is the default rather than a configuration exercise.
What is the cheapest way to deploy a side project, Fly.io or Railway?
For a single small service, both Fly.io and Railway can look inexpensive on paper. The headline price rarely matches the real bill. Per-service billing, metered bandwidth, build minutes, and add-ons for databases or key-value stores stack up quickly, and neither platform offers a hard spending cap to stop a surprise invoice. The cheapest predictable option is one with fixed monthly pricing and an enforced ceiling. Runsite bills in EUR from €5/month with hard spending caps and Telegram alerts, plus a permanent free tier, so a side project stays cheap by design, not by careful monitoring.
