Fly.io vs Netlify
Fly.io vs Netlify 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 Netlify: quick answer
Fly.io and Netlify both offer Git-push deploy workflows, but they differ where it counts. Fly.io and Netlify 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.

Common Fly.io frustrations. Sound familiar?
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.
Runsite solution
Git push and done
Connect your GitHub repo, pick a region, deploy. No config files, no CLI learning curve.
Fly.io problem
"Fly.io is a US company"
Even with EU regions, Fly.io is subject to US jurisdiction and the CLOUD Act.
Runsite solution
EU-registered entity
Runsite is an EU company. Your data is governed by European law, period.
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
Know exactly what you'll pay. Set a spending limit that can't be exceeded.

What about Netlify?
Netlify excels at static sites. Runsite handles everything else: backend, databases, and full-stack apps on EU servers.
// netlify problems → runsite solutions
Common Netlify frustrations. Sound familiar?
Every Netlify frustration, solved.
Netlify problem
"Netlify can't host my backend"
Netlify Functions are limited to 10-second execution. Long-running APIs need a separate hosting provider.
Runsite solution
Persistent containers for any backend
Run long-lived processes, WebSocket servers, background workers: anything Docker can run.
Netlify problem
"No managed databases"
Netlify doesn't offer databases. You need PlanetScale, Supabase, or AWS RDS on top.
Runsite solution
PostgreSQL + Redis included
Managed databases on the same platform. One bill, one dashboard, one support channel.
Netlify problem
"Compute runs in the US"
Netlify Functions run in US regions by default. EU users get higher latency.
Runsite solution
EU-only compute and storage
Everything runs in our Frankfurt (eu-central) region. Sub-20ms for users in DACH and Benelux, single-digit ms within Germany.

How Fly.io and Netlify 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.
Netlify vs Runsite
Your side project began as a static Astro site, then someone asked for a contact form, and now you need a backend. That is where many teams hit the edge of what Netlify does well. Netlify essentially created the Jamstack deployment category, and for static sites, SPAs, and projects built with Gatsby, Hugo, or Astro, its build pipeline and global CDN are excellent. The free tier for static hosting is genuinely generous, and deploy previews and split testing are well-implemented.
Backends are the sore spot. Netlify Functions are serverless with a 10-second execution limit, there are no managed databases, and compute runs on US-based infrastructure. Grow past static content and you stitch together Netlify for frontend, a separate provider for your API, and another for your database. Runsite hosts full-stack applications on one platform: Docker containers for any backend, managed PostgreSQL, and S3 storage, all in EU data centers.
If your project has outgrown Jamstack constraints and you want one platform for frontend, backend, and database with GDPR compliance built in, Runsite consolidates what would be three separate services.

Common Questions
FAQ
Which is better for EU hosting, Fly.io or Netlify?
Neither Fly.io nor Netlify 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 Netlify?
Free tiers on both Fly.io and Netlify 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 Netlify GDPR-compliant?
Both Fly.io and Netlify 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 Netlify?
For a single small service, both Fly.io and Netlify 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.
