chatdev

Why we included this project

ChatDev IDE is a browser extension that gives you a visual workspace for building LLM-powered agents. Instead of editing prompts in a text file, you assemble flows as a graph of nodes, each with its own prompt and optional JavaScript, while a YAML editor and live visualization let you watch execution move through the flow. The same tooling works for game-style NPCs in a simulated town: you define role prompts and then walk an avatar up to a character to test the behavior in context. It also includes a plain chat window and supports models beyond OpenAI, including Claude, Bard, and several open-source options. For teams prototyping agents or NPCs who want to iterate on prompts visually rather than through code-only loops, the flow editor and import/export of agent definitions are genuinely useful.
