Reviewer scorecard
“For apps that need full server control — WebSocket servers, background workers, AI inference — Fly.io gives you the flexibility that serverless platforms don't.”
“Essential for any production app. Source maps, breadcrumbs, and release tracking make debugging 10x faster.”
“The DX has improved massively but it's still more complex than Vercel. You need to understand Docker and infrastructure. Not for beginners.”
“The free tier is generous and the core error tracking is genuinely best-in-class. Session replay is a nice bonus.”
“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.”
“Session replay lets you see exactly what users experienced before errors. Invaluable for debugging UI issues.”
