Open source agentic operating system
npm install eliza
What is this?
elizaOS is an open-source, local-first operating system for AI agents. Two parts:
- Eliza — the app. An AI assistant for desktop, mobile, and web: chat, voice, your messaging accounts, a personal-assistant brain, a non-custodial wallet, browser automation, and on-device models.
- elizaOS — the runtime and the OS underneath it. The same runtime can take over the whole machine — boot a Linux desktop or run on Android as the system assistant.
The agent, your data, and the models all run on your device. Eliza Cloud is optional — add it for hosted inference, sync, and deploys.
Get Eliza
| Platform | How |
|---|---|
| Web | Open app.elizacloud.ai |
| Desktop — macOS · Windows · Linux | Download from GitHub Releases |
| iOS · Android | App Store · Play · sideload |
Run from source:
git clone --filter=blob:none https://github.com/elizaos/eliza.git
cd eliza
bun install
bun run dev # API + the Eliza app UI
To run a whole device as elizaOS instead, see elizaOS — the operating system.
What Eliza does
The app ships with:
- 💬 Chat — one inbox for your agent and your accounts (iMessage, Discord, Telegram, WhatsApp, Slack, Farcaster, X).
- 🎙️ Voice — hands-free voice with on-device transcription and natural speech.
- 📇 Phone · Messages · Contacts — telephony and SMS surfaces (native on Android).
- 🧠 Personal assistant — calendar, reminders, inbox triage, tasks, daily brief, and owner-approved actions.
- 🌐 Browser & computer use — the agent drives a real browser and desktop.
- 👛 Wallet — non-custodial EVM + Solana: transfers, swaps, bridges, LP. Every spend needs your OK.
- 📄 Documents — ask questions over your files (RAG).
- 📷 Camera & vision — capture and reason over images.
- ⚙️ Automations — schedule recurring work; pick models and routing.
Private by default
Eliza can run the whole pipeline on your device via Eliza-1, the on-device model family (Gemma-4):
- Text generation and embeddings, from ~2B (phone) to ~27B (desktop).
- Voice — local speech-to-text and text-to-speech; audio never leaves the device.
- Vision & images — on-device description and generation.
Pick a model in Settings → Model Routing and it downloads and pins; from then on it works with no network.
Apps on elizaOS
elizaOS runs apps, not just an agent. An app is a plugin that adds a surface inside Eliza; the runtime installs, launches, and tracks it like real software, and it survives restarts.
- Browse & install — catalog at plugins.elizacloud.ai; curated entries in
packages/registry, plus any npm package taggedelizaos. - First-party apps —
plugin-browser,plugin-documents,plugin-phone,plugin-task-coordinator. - Earn — apps deployed through Eliza Cloud can be metered and monetized.
elizaOS — the operating system
packages/os is the real, bootable distribution. Downloads and hardware are at os.elizacloud.ai.
- Linux (
packages/os/linux) — boots a full desktop with Eliza built in from a USB stick. amd64 · arm64 · riscv64. - Android (
packages/os/android) — Eliza is the system launcher and assistant, on Pixel-class devices.
The OS is bootable today; full device certification and production update channels are in progress — see the per-target READMEs for status.
Eliza Cloud (optional)
Optional managed backend for going beyond one device. Never required — local-only is first-class. It adds:
- Auth — accounts and sign-in (OAuth/SIWS).
- Hosted inference — model routing across providers, billed per use.
- Deploy — push an agent or app to a container with its own domain.
- Sync & bridge — state across devices; drive a local agent from the cloud dashboard.
- Monetization — metering and creator earnings for published apps, agents, and MCPs.
Build on elizaOS
The runtime is open source and yours to extend. Start with the CLI:
bun add -g elizaos@beta
elizaos create my-app --template project # a deployable app workspace
elizaos create my-plugin -t plugin # a runtime plugin (action/provider/service)
The runtime is model-agnostic (OpenAI, Anthropic, Gemini, Grok, Llama, local Eliza-1, …) and extended through a small set of primitives:
@elizaos/core(packages/core) — the agent loop, plugin model, and message/memory/state primitives.@elizaos/agent(packages/agent) —AgentRuntime, the plugin loader, and the default plugin map.@elizaos/app-core(packages/app-core) — the API + dashboard host that runs agents.elizaos(packages/elizaos) — the CLI:create,info,upgrade.
A plugin exports a Plugin that registers actions (what the agent does), providers (prompt context), services (long-lived singletons), and evaluators (post-response work). Import @elizaos/core directly to use the runtime with no CLI or UI — see packages/examples and the evaluation suites in packages/benchmarks. Full guides: docs.elizaos.ai.
Working in the monorepo
bun install # workspace install
bun run install:light # skip the large artifact download when disk or time is tight
bun run dev # API + Vite UI for apps/app
bun run build # turbo build across the workspace
bun run test # full test suite
bun run cloud:mock # boot the local cloud backend stack with mocks
The repo is self-contained — runtime, CLI, dashboard, native OS forks, cloud backend, and first-party plugins all live here. Every package carries its own README.md; read it before working inside. Tree map: AGENTS.md.
Contributing
Contributions welcome. Open an issue before sending a non-trivial PR. Before
opening a PR, read CONTRIBUTING.md and the evidence standard
in AGENTS.md; frontend-testable changes need screenshots (JPG), an
MP4 video walkthrough, logs, and any relevant real-LLM trajectories attached
inline in the PR itself. Agents and maintainers working from a GitHub Project
board use the coordination workflow in CONTRIBUTING.md before
claiming kanban work. Active MVP work is coordinated on the
LifeOps Personal Assistant MVP board
and in Discussions; in-flight
design docs live in
packages/docs/ongoing-development/.
