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.”
“Model Garden gives you access to every major model with enterprise security. Feature Store and pipelines are production-grade.”
“The DX has improved massively but it's still more complex than Vercel. You need to understand Docker and infrastructure. Not for beginners.”
“GCP complexity tax is real. Unless you're already on Google Cloud, the onboarding friction isn't worth it.”
“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.”
“Google's AI infrastructure advantage (TPUs, models, data) makes Vertex the dark horse enterprise AI platform.”
