Agent Zero — Self-Hosted, Open-Source

Agent Zero is a personal, organic agentic framework that grows and learns with you. It is fully Dockerized and includes features like Speech-to-Text and TTS. **Key Features:** - **General Purpose Assistant:** Can handle various tasks. - **Computer Use:** Can use the computer (in the container). - **Coding:** Can write and execute code. - **Memory:** Learns from interactions. **Getting Started:** 1. Launch Agent Zero. 2. Configure your models in the settings. ⚠️ **Warning:** Agent Zero can execute code. Run with caution.

Agent Zero is commonly used as a self-hosted alternative to ChatGPT, Claude, Copilot. Replacing a SaaS tool with a self-hosted equivalent lets you avoid recurring subscription fees, keep full control of your data, and continue working even when the original vendor changes pricing, ships limits, or shuts down.

Features

It has a persistent memory, allowing it to memorize previous solutions, code, facts, instructions, etc., to solve tasks faster and more reliably in the future.
Agent Zero uses the operating system as a tool to accomplish its tasks. It has no single-purpose tools pre-programmed. Instead, it can write its own code and use the terminal to create and use its own tools as needed.
The only default tools in its arsenal are online search, memory features, communication (with the user and other agents), and code/terminal execution. Everything else is created by the agent itself or can be extended by the user.
Tool usage functionality has been developed from scratch to be the most compatible and reliable, even with very small models.
Default Tools: Agent Zero includes tools like knowledge, code execution, and communication.
Creating Custom Tools: Extend Agent Zero's functionality by creating your own custom tools.
Every agent has a superior agent giving it tasks and instructions. Every agent then reports back to its superior.
In the case of the first agent in the chain (Agent 0), the superior is the human user; the agent sees no difference.
Every agent can create its subordinate agent to help break down and solve subtasks. This helps all agents keep their context clean and focused.
Browser automation is provided by the built-in _browser_agent plugin.

Installation

docker run -p 80:80 agent0ai/agent-zero

Why self-host Agent Zero

Self-hosting gives you three things SaaS can’t: data ownership (the files live on disks you control), cost predictability (a one-time setup vs. recurring per-seat fees that grow with your household or team), and longevity (open-source means the app keeps working even if the maintainers move on, since you can pin a working version). The trade-off is that you take on the operational work of running a server, applying updates, and handling backups.

What hardware do you need

Most self-hosted apps run comfortably on modest hardware — a Raspberry Pi 4, a mini PC, a NAS with Docker support, or a small VPS is usually enough for personal or family use. CPU and RAM requirements scale with how many simultaneous users or how much data you push through Agent Zero. Storage requirements depend on the kind of data you keep; check the README for guidance on data retention.
