IN THE FIELD GUIDE
fly.io
Fly.io offers a platform to deploy apps, agents, and databases on hardware-isolated virtual machines that launch instantly and run only when needed. It supports persistent, stateful environments called Sprites for running arbitrary code safely with fast startup and per-second billing.

Candidates based on category and primary feature. Check feature and pricing differences before switching.
Railway is a full-stack cloud platform for deploying web apps, servers, and databases with automatic scaling, monitoring, and security. It offers a visual canvas for infrastructure management and automates configuration and networking setup.
Render is a cloud infrastructure platform that enables deployment and scaling of apps, APIs, agents, databases, and more with zero operations. It provides integrated features like autoscaling, private networking, managed databases, and observability to support modern web applications from first user to billions.
Lizard is an AI-native deployment platform designed specifically for coding agents, enabling deployment from Claude Code, Codex, or Cursor. It provides managed Postgres, Redis, S3 storage, and agent-readable logs, with per-second billing based on actual resource usage rather than reserved capacity.
DenkOps is a platform that hosts backends, APIs, MCP servers, AI agents, and background jobs, allowing deployment directly from AI coding agents without managing servers or DevOps. It provides EU-hosted managed infrastructure with built-in authentication, zero-trust egress, and a flat pricing model based on slots.
