Which one should you pick?

Pick Shopify if…

  • Your customer base is concentrated in US / GLOBAL.
  • E-commerce platform — store builder, payments, inventory, shipping. The default for D2C brands.

Pick Fly.io if…

  • Your customer base is concentrated in IN / US / GLOBAL.
  • Run full apps in 35+ regions worldwide via Firecracker microVMs. Best for latency-sensitive global products. Pay per VM-second, free tier removed in 2024.
  • Entry pricing matters and you don't need a feature Shopify bundles at its tier.

FAQ

Is Shopify or Fly.io cheaper?

Fly.io starts at $5/mo, Shopify starts at $39/mo — Fly.io wins on entry pricing. But entry pricing is rarely your real cost; check our pricing-curve modelling on each tool's review page for ARR projections.

When should I pick Shopify over Fly.io?

Both compete in the same engineering space. Pick Shopify if your stack is closer to its native integrations, your team already uses sister products from the same vendor, or its regional coverage matches your customer base. Pick Fly.io for the inverse.

Can I migrate from Shopify to Fly.io later?

Most modern SaaS supports CSV/JSON export for the core data model. The migration cost is integration work — every Zapier workflow, every webhook URL, every API token has to be re-wired. Budget 2-4 weeks of engineering time for a non-trivial production migration.
