Durable Vibes

Experience a live demo of multiplayer coding with Cursor SDK and Durable Objects, showcasing real-time collaboration and persistent state.

Overview
Tech stack
  • Cursor
    The AI-native code editor designed for high-velocity development through deep LLM integration.
    Cursor is a fork of VS Code that embeds AI directly into the development workflow while maintaining full extension compatibility. It leverages models like Claude 3.5 Sonnet and GPT-4o to power features such as Cmd+K for inline edits and Cmd+L for codebase-wide chat. By indexing local files, Cursor provides precise context for its predictive 'Tab' completions and multi-file 'Composer' mode. This setup allows engineers to move from high-level intent to functional code without leaving the editor or losing context.
  • Durable Objects
    Durable Objects deliver globally unique, single-threaded compute instances with strongly consistent, transactional storage, enabling stateful serverless applications.
    Durable Objects (DOs) are a core primitive of the Cloudflare Workers platform: they combine compute with isolated, persistent storage. Each DO instance is globally addressable by a unique ID, guaranteeing that only one instance of the object executes at any given time, which completely eliminates race conditions and the need for distributed locks. This single-threaded Actor model simplifies building complex stateful systems. Use DOs for real-time coordination: think collaborative editing, multiplayer game sessions, or managing millions of individual user workspaces. The attached storage is fast, transactional, and strongly consistent, supporting up to 10 GB of data or a SQLite backend, all without managing any infrastructure.
