Reviewer scorecard
“Docker is infrastructure. Every modern deployment pipeline uses it. The AI features in Docker Desktop are helpful for debugging but the core value is containerization itself.”
“For apps that need full server control — WebSocket servers, background workers, AI inference — Fly.io gives you the flexibility that serverless platforms don't.”
“Docker Desktop on Mac still uses too much memory. But Docker itself is essential. Podman is a lighter alternative if Desktop bloat bothers you.”
“The DX has improved massively but it's still more complex than Vercel. You need to understand Docker and infrastructure. Not for beginners.”
“Containers are the universal packaging format for software. AI agents, ML models, microservices — everything ships in containers. Docker is infrastructure.”
“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.”
