Reviewer scorecard
“Best-in-class observability. APM, logs, and metrics in one place with excellent correlation. Worth every penny for production systems.”
“For apps that need full server control — WebSocket servers, background workers, AI inference — Fly.io gives you the flexibility that serverless platforms don't.”
“The pricing model is designed to surprise you. Custom metrics, log ingestion, and APM spans add up to terrifying bills.”
“The DX has improved massively but it's still more complex than Vercel. You need to understand Docker and infrastructure. Not for beginners.”
“Datadog's land-and-expand across security, CI, and database monitoring makes them the observability platform to beat.”
“Fly.io is the answer for workloads that don't fit the serverless model. As AI inference goes local-first, having servers in 30+ regions matters.”
