FAQ
›Is Fly.io or Axiom cheaper?
Fly.io starts at $5/mo, Axiom starts at $25/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 Fly.io over Axiom?
Both compete in the same engineering space. Pick Fly.io 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 Axiom for the inverse.
›Can I migrate from Fly.io to Axiom 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.
