The offer

  • Free trial: 2 total VM-hours of runtime or 7 days, whichever comes first, no credit card to start
  • Trial includes up to 10 machines, 20 GB volume storage, and up to 2 vCPUs / 4 GB RAM per machine
  • Trial machines auto-stop after 5 min of running to stretch the 2 hours
  • After the trial: pure usage billing (e.g. shared-cpu-1x 256 MB ≈ $1.94/mo; stopped machines billed only ~$0.15/GB-month rootfs)
  • 40% discount via prepaid machine-reservation blocks once usage is predictable

Who qualifies

  • Anyone, no payment method to start the trial (adding a card ends the trial and starts billing)
  • The old always-free allowance is gone for new accounts. Only pre-Oct-2024 Hobby/Launch/Scale orgs keep it
  • No VC or stage gating; no named startup program
  • Fly GPUs are deprecated and unavailable after August 1, 2026, not a fit for GPU or AI workloads

Community Insights

Fly.io is well-liked for small projects and apps that need to run near users, and developers still cite the pay-as-you-go plus rapid-scaling model as the thing that makes it worth using. The persistent caveat is reliability: uptime gets mixed reviews. The strategic direction matters too. Fly removed the always-free tier for new users and is deprecating GPUs (gone after August 1, 2026), so any AI or GPU plan should look elsewhere.

Best Practices (from community tips)

  • Use the trial to deploy one real app and measure. 2 VM-hours goes fast, and trial machines auto-stop at 5 min.
  • Add a card only when you’re committed. Doing so ends the trial instantly.
  • Lean on auto-stop / auto-start and stopped-machine pricing (~$0.15/GB-month) to approximate scale-to-zero.
  • Prepay reservation blocks for 40% off once usage is predictable.
  • Do not plan GPU or AI workloads on Fly. GPUs are deprecated after August 1, 2026.
  • For multi-region apps, opt into granular bandwidth pricing to cut cross-region transfer costs.
