Reviewer scorecard
“Run any Docker container globally with `fly launch`. The Machines API for programmatic VM creation is uniquely powerful.”
“The per-request pricing model is perfect for side projects — you literally pay nothing until you have traffic. Redis commands at $0.2/100K is incredibly cheap.”
“Global deployment is its strength. For edge-first architectures, Fly.io solves distribution better than anyone.”
“At high scale, per-request pricing can get expensive vs a fixed Redis instance. Know your traffic patterns. For most indie hackers and startups, it's a no-brainer.”
“Apps running close to users is the future. Fly.io's Machines API enables new categories of distributed applications.”
“Upstash is doing for Redis what Neon did for Postgres — making it serverless-native. The QStash message queue is an underrated piece of the puzzle.”
