Declared compatibility
Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

Fly.io API Skill
Quick Start
Fly.io transforms Docker containers into microVMs running globally. The Machines API allows you to programmatically spawn, pause, and destroy VMs in milliseconds.
# Fly Machines API operates over standard HTTP RESTCommon Workflows
Fast Machine Provisioning
Instead of scaling via traditional auto-scalers, use the Fly Machines API to launch a new microVM the moment a user requests a heavy workload (e.g., video rendering) and immediately destroy it once the workload completes.
Production Patterns
Global Anycast
Fly automatically routes HTTP traffic to the nearest microVM via Anycast. Ensure your database (e.g., Turso or a Fly Postgres read-replica) is also positioned in the same region to avoid cross-country latency penalties.
Error Recovery
Handle HTTP 503 errors if attempting to start a Machine in a region experiencing hardware capacity constraints. Always implement a fallback region (e.g., sjc falling back to lax).
Security Notes
Machines can communicate with each other over an encrypted private IPv6 network (6PN). Do not expose internal microservices to the public internet; restrict their services block in the fly.toml.
Performance Considerations
Machines boot incredibly fast (often `); this is almost always caused by an application crash (e.g., missing environment variables) rather than a Fly infrastructure issue.

AI pitfalls
- Using outdated SDK or API versions from training data
- Inventing environment variable names
- Omitting error handling and retry logic
Production checklist
- [ ] Secrets in environment variables, not source code
- [ ] Error handling and logging in place
- [ ] Rate limits and timeouts configured
