Overview

Life.js is the first fullstack agent framework. Think of it as « the Next.js for agents ».

It has been specifically crafted for Typescript/React, with a minimalist, low-abstraction, extensible, and end-to-end typesafe design. Read more about our philosophy.

How does it feel?

          // Insert agent demo with:
          // - Preview / Code tabs
          // - On the preview, hints like "Ask the agent about that dashboard/counter"

In 20 lines of code, you have a voice agent that can see and interact with the page content.

The basics

• Control exactly what the agent has "in mind" with Memories
• Allow the agent to perceive the interface with Percepts
• Execute blocking and non-blocking logic with Actions (tools)
• Run stateful, and multi-step logic with Flows

And that's it! You've understood the basics of Life.js.

Fancy highlights

Here are some of the features we are especially proud of:

Non-blocking Actions

Percepts

Client-side Actions

Simple, but powerful

If we were to compare a Life.js agent to a human:

• Memories would be their brain 🧠 (knowledge and short-term memory)
• Percepts would be their eyes 👀, ears 👂, and other feelings 🤌
• Actions and Flows would be their arms and legs 💪👖
