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.”
“Best DX for deployment. `railway up` and you're live. Databases, cron, and private networking just work.”
“The DX has improved massively but it's still more complex than Vercel. You need to understand Docker and infrastructure. Not for beginners.”
“The Heroku successor done right. Fair usage-based pricing and none of the cold start nightmares.”
“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.”
“Railway is building the best developer experience in cloud hosting. They understand what developers actually want.”
