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.”
“The lingua franca of infrastructure as code. Provider ecosystem covers every cloud service imaginable.”
“The DX has improved massively but it's still more complex than Vercel. You need to understand Docker and infrastructure. Not for beginners.”
“BSL license change was controversial but the tool remains essential. OpenTofu is the hedge if needed.”
“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.”
“Infrastructure as code is table stakes. Terraform's provider ecosystem is its moat and it keeps growing.”
