What is it?

elizaOS is a monorepo for building and running autonomous AI agents. It includes a core runtime (@elizaos/core) that defines agent state, memory, authorization, and a plugin contract, along with a standalone agent host, a shared React UI, and a CLI.

Plugins are the main extension point. A plugin can register actions, providers, evaluators, services, model handlers, routes, and app views. The repository ships first-party plugins for model providers, messaging connectors, domain features, and device bridges, and it includes a local inference path (Eliza-1) based on Gemma 4 text tiers and local embedding, speech, and vision assets.

The Eliza app targets web, desktop, and mobile, and Eliza Cloud is an optional hosted service for accounts, model routing, and deployment. Developers can run the stack from source with Bun, or import @elizaos/core to embed the runtime directly.

Key features

  • 01Core runtime with agent state, memory, and plugin contracts
  • 02Plugin system for actions, providers, evaluators, services, and routes
  • 03Local inference path with Eliza-1 model tiers and device-based routing
  • 04Messaging and workspace connectors, plus browser and desktop automation
  • 05Non-custodial EVM and Solana wallet operations with approval steps
  • 06Model-agnostic: local, direct-provider, or Eliza Cloud backends

Use cases

  • Building a custom autonomous agent that connects to chat platforms like Discord, Slack, or Telegram
  • Writing a first-party-style plugin that adds model handlers or actions to an agent
  • Running a personal assistant with local models on supported hardware
  • Embedding the agent runtime in an existing TypeScript application

Quick start

  1. 1

    Install the Bun and Node versions pinned in package.json

  2. 2

    Clone the repository

    git clone --filter=blob:none https://github.com/elizaos/eliza.git
  3. 3

    Enter the folder and install dependencies

    cd eliza && bun install
  4. 4

    Start the app in development mode

    bun run dev

Things to know

  • Running from source needs specific Bun and Node versions and sets up submodules and native build prerequisites.
  • Local inference needs supported hardware and downloads model assets before offline use.
  • Some capabilities depend on model provider keys or optional Eliza Cloud services.
