Stateful Agents Meetup: Vibecoding full-stack agentic apps
Build a Complete AI Agent Application Without Writing a Single Line of Code
Join Charles Packer, CEO/co-founder of Letta and creator of MemGPT, for a demonstration of how to build fullstack agentic applications through pure vibecoding.
In this live coding demo, Charles will demonstrate the future of agent development by creating a complete AI agent application without writing any code. Watch as he:
Creates a custom stateful agent with self-editing memory blocks, custom tools (including MCP), tool rules (agent guardrails), and sleep-time compute - all via pure prompting on top of the Letta SDK (Python/Node/Vercel AI SDK)
Builds a complete web app using tools like using Cursor and Loveable, on top of the Letta stateful agents server
Deploys a production-ready agent application that can scale to millions of agents, each with their own persistent memory and infinite context
All without typing a single line of code.

Bring a laptop if you want to follow along. No coding required, just an internet connection, a web browser, and good ✨vibes✨.
