Overview

Fly.io is a platform for running full-stack apps and databases close to users with automatic scaling. It handles edge computing, global deploy, gpu support, and machines api, and it's best suited for developers wanting to run apps close to users globally. It has been around since 2017, giving it a 9-year head start in building out integrations and refining the product.

The free plan offers generous free tier. It's designed for small teams, striking a balance between simplicity and collaboration features.

Strengths

  • Includes Edge Computing as a core feature, purpose-built for cloud hosting workflows
  • Includes Global Deploy as a core feature, purpose-built for cloud hosting workflows
  • Generous free tier — generous enough for most small teams to get real work done
  • Includes gpu support alongside the core feature set — fewer separate tools needed

Weaknesses

  • Free plan exists but key features are locked behind the paid upgrade
  • Developer-oriented tooling may not suit non-technical team members
  • Costs can spike unexpectedly during traffic surges if limits aren't configured
  • Limited team/admin features if your organization eventually scales up
