Durable Objects

What it does

This skill enables AI agents to provision and manage Cloudflare Durable Objects, providing serverless stateful compute for applications requiring persistent data storage. It allows agents to create isolated environments where objects retain state across invocations while scaling automatically with demand.

When to use it

• Building real-time chatbots or gaming backends that require maintaining conversation history or player scores between sessions.
• Developing session-based services like shopping carts or form drafts that must persist user data without managing database connections manually.
• Creating high-throughput microservices where stateful logic needs to scale horizontally without complex sharding strategies.
• Prototyping serverless applications that need guaranteed uptime and automatic scaling without provisioning dedicated servers.

Key capabilities

• Automatically scales compute resources based on demand, ensuring performance during traffic spikes.
• Provides isolated execution environments for each object instance to prevent data conflicts.
• Maintains persistent state across function invocations within the same object namespace.
• Integrates seamlessly with Cloudflare's global edge network for low-latency access worldwide.

Example prompts

• "Provision a Durable Object to store user session tokens for my authentication service."
• "Create a stateful worker using Durable Objects to track inventory levels for an e-commerce site."
• "Set up a persistent queue manager in a Durable Object to handle background job processing."

Tips & gotchas

Ensure your application logic is designed around the object-based model, as each Durable Object instance has its own isolated state. Be mindful of cost implications when creating many short-lived objects versus fewer long-running ones, as usage is billed per second of execution time.
