Chucky SDK

Chucky provides Claude as a Service - a fully managed infrastructure for deploying AI agents powered by Claude. Build conversational AI applications without managing servers, handling authentication complexity, or worrying about scaling.

​
What is Chucky?

Chucky is a platform that lets you integrate Claude into your applications with:
  • Managed Infrastructure: Sandboxed execution environments running on Cloudflare’s edge network
  • Built-in Billing: Per-user budget controls with real-time usage tracking
  • Multi-language SDKs: First-class support for JavaScript/TypeScript and Python
  • Tool Execution: Define custom tools that run on the server or in the browser
  • Session Persistence: Multi-turn conversations with automatic state management
