Reviewer scorecard
“The serverless standard. Event sources, layers, and container image support cover every use case.”
“For apps that need full server control — WebSocket servers, background workers, AI inference — Fly.io gives you the flexibility that serverless platforms don't.”
“Cold starts have improved dramatically. For event-driven workloads, Lambda's pricing model is unbeatable.”
“The DX has improved massively but it's still more complex than Vercel. You need to understand Docker and infrastructure. Not for beginners.”
“Serverless is the default compute model. Lambda's ecosystem and AWS integration ensure its dominance.”
“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.”
