fx0
fx0 is an open-source design agent built to showcase libfx's speed and durability.
Describe a page in the chat and it shows up here as one HTML file.
when you send
libfx runs the agent inside a Vercel Function. It calls the model and the tools and streams each step to your tab.
durable
Each chat is a libfx session, saved step by step in a Workflow world. If the function dies mid-reply, a new one picks up from the last step.
make it yours
The instructions are in lib/agent.ts and the tools in lib/tools.ts.
