      Spotsaas Editor’s POV generated by AI

      Buyer sentiment

      Buyer sentiment is positive across 180 reviews, with strong overall satisfaction.

      What buyers like

      • Global edge deployment across 35+ regions puts applications close to users worldwide without configuring multi-region infrastructure manually.
      • Firecracker VM isolation provides hardware-level security between tenants — stronger than container-based isolation offered by most PaaS platforms.

      Common complaints

      • More complex than Render or Railway — Fly.io requires more CLI knowledge and configuration, with a learning curve that can delay first deployments for teams new to infrastructure.
      • Usage-based pricing without published unit prices makes cost estimation harder before running a workload — billing surprises are a common complaint from new users.
