The Verdict
Fly.io is built for full stack developers and global apps, with a focus on global-deployment and firecracker-vms. New Relic targets development teams and sre teams and leads with apm and infrastructure-monitoring.
Both tools come in at similar price points ($0/mo for Fly.io, $0.3/mo for New Relic), so pricing won't make the decision for you.
Both offer free plans, so you can test each with your real workflow before committing to a subscription.
Feature-wise, New Relic offers broader built-in capabilities (8 features vs 7), while Fly.io takes a more focused approach — which can mean a simpler, faster onboarding experience.
This is a genuinely close comparison. If you can, sign up for both free trials (where available) and run a one-week test with your actual team tasks before deciding.
