Should I use Fly.io?

Sandboxes aren't enough. Give your agent a real computer and get back to building. - fly.io

Buy if your engineering team needs secure, globally deployed VMs for real apps or AI agents and can handle infra itself. Not for non-technical buyers or anyone needing upfront pricing; confidence is low — this verdict rests on a single vendor page.

Confidence

Low. Based on 1 public source (vendor security page). No reviews, pricing, or company funding data found; confidence is low.

Best for

  • Engineering teams running real apps
  • Builders deploying AI agents
  • Compliance-driven teams (SOC 2, BAAs)
  • Global low-latency app hosting

Not for

  • Non-technical founders wanting hands-off hosting
  • Teams needing published pricing before purchase
  • Simple static sites or pure serverless workloads
  • Buyers wanting independent user reviews first — none exist in sources

Gotchas - check before you buy

medium

Guess: usage-based billing can spike fast; no pricing appeared in reviewed sources, so model costs first

medium

Only evidence located is vendor marketing; zero independent reviews found

low

Managed Postgres runs on Supabase; key-value on Upstash — extra vendors in your stack

low

SOC 2 reports, BAAs, and pentest intros require a sales conversation

Pros and cons

Pros

  • SOC 2 Type 2 certified; ISO 27001 datacenters; BAAs available
  • Containers run as isolated VMs — tenants never share kernels
  • WireGuard-encrypted network; automatic A-grade TLS out of the box
  • Third-party pentests by Atredis Partners, Doyensec, and Tetrel
  • Zero-config private networking: no Terraform, VPC setup, or IAM

Cons

  • No independent user reviews found; all evidence is vendor marketing
  • Requires engineering skill; not a no-code or hands-off host
  • Key managed services are third-party brands: Supabase Postgres, Upstash

Sources & method

- 1 source - No known vulnerabilities found in the sources reviewed. Vendor claims strong posture: SOC 2 Type 2, VM hardware isolation, WireGuard encryption, named pentest firms.
