Reviewer scorecard
“Run any Docker container globally with `fly launch`. The Machines API for programmatic VM creation is uniquely powerful.”
“The most mature AI developer platform. Assistants API, function calling, and the Playground are all well-designed. Documentation is extensive.”
“Global deployment is its strength. For edge-first architectures, Fly.io solves distribution better than anyone.”
“Reliability has improved dramatically. The rate limits are generous on paid tiers. The Assistants API is finally stable enough for production.”
“Apps running close to users is the future. Fly.io's Machines API enables new categories of distributed applications.”
“OpenAI has the largest ecosystem of developers and integrations. Even if other models catch up, the platform moat is real.”
