Description
ElizaOS is an open source operating system for AI agents, built by Eliza Research, a small team that describes itself as building in the open at the intersection of artificial intelligence and the people who use it. Rather than a single chat app, it is a foundation other software, including the team's own products, runs on.

The best known product built on ElizaOS is Eliza, a personal agent designed to live alongside a user: it remembers past interactions, keeps a schedule, connects to the tools someone already uses, and can act on their behalf across every device it runs on, from a laptop to a phone to a user's own server. On GitHub, the elizaOS/eliza repository is described simply as an "open source agentic operating system."
Being open source is the core design choice. Anyone can inspect the code, self-host it, and extend it instead of depending on a single vendor's roadmap or being locked into one company's agent platform. The project is auditable end to end, which matters for anyone who wants to know exactly what an agent acting on their behalf is doing.
Eliza Research also runs a separate project, slop.cash, described as a swarm contribution platform: people can post a problem, fund it, and let a crowd of human and machine contributors work on it for pay. It sits alongside ElizaOS as a related project from the same team rather than a feature of the operating system itself.
ElizaOS suits developers who want to build or run their own agents without being tied to a single provider, and anyone who wants to run the Eliza personal agent on infrastructure they control. As an open source project, using it means working with code directly (cloning the repository, running it yourself) rather than signing up for a hosted consumer product with a simple onboarding flow.

ElizaOS's Core Features
Open source agentic operating system that anyone can inspect, audit, or modify.
Runs on infrastructure the user controls, including a laptop, phone, or their own server.
Eliza, a reference personal agent built on ElizaOS, remembers context and keeps a schedule.
Eliza connects to a user's existing tools and can act on their behalf across devices.
Designed to avoid vendor lock-in by staying fully open source rather than a closed platform.
Development happens in the open, with code and issues hosted on GitHub.
slop.cash, a related swarm contribution platform from the same team, lets people post and fund problems for a crowd of contributors.
How to use ElizaOS?
Explore the project: Read the elizaOS/eliza repository on GitHub to see the code and documentation.
Set up ElizaOS: Clone or install the open source operating system on your own machine or server.
Run Eliza: Configure the reference agent to connect to your accounts and tools so it can act for you.
Extend or audit: Modify the open source code directly since there is no closed platform layer around it.
Follow the project: Track updates on GitHub or X, or contact the team directly to build alongside them.
