How much does Agent Zero cost?

Free and open-source (self-hosted), so direct costs are limited to your own LLM API usage and compute. Optional support via GitHub Sponsors. The same team also offers Space Agent, a more polished workspace product, as a separate direction.

What are the best alternatives to Agent Zero?

Based on documented capability coverage across the Agentic Index 14 point taxonomy, the closest alternatives to Agent Zero among multi-agent platforms are Pokee AI, SimplAI, Akka, CrewAI. Each is graded on the same public evidence, and no vendor pays for placement.

Does Agent Zero support MCP and tool calling?

Full under the Agentic Index verification standard. Agent Zero publishes public evidence of Model Context Protocol (MCP) support, tool calling, and API or SDK extensibility for connecting agents to external tools. Evidence basis: Is open source and built for extension through a prompt driven design, a plugin and Skills system, a command line, and a streamable Model Context Protocol server that exposes its capabilities to other tools, a comprehensive extensibility su.

Can Agent Zero be self hosted or run in a private VPC?

Full under the Agentic Index verification standard. Agent Zero publishes public evidence of self hosted or private VPC deployment, along with data residency options for controlling where agent data is processed and stored. Evidence basis: Is open source under a permissive license and runs entirely self hosted in a Docker container, on a desktop launcher, or as a remote instance, and works with local models through Ollama for private offline operation, real self hosting and d.

Can you bring your own model or route between providers with Agent Zero?

Full under the Agentic Index verification standard. Agent Zero publishes public evidence of bring your own model and bring your own key (BYOK), and of routing tasks between models or providers rather than being locked to one. Evidence basis: Is provider agnostic across OpenAI, Anthropic, xAI Grok, Google, OpenRouter, GitHub Copilot, and local models through Ollama, and lets you assign different models to different agent roles, genuine multi provider and role based model selecti.

Open-source multi-agent framework with its own Linux-VM agent, subordinate agents, and dynamic tool creation.

Agent Zero is an open-source agentic framework that gives an AI agent a full Linux system inside a single Docker container, rather than a fixed set of pre-built tools. The agent uses that environment as its workbench: writing and running code, driving a real XFCE desktop and a built-in browser, editing documents and spreadsheets alongside the user, and creating its own tools on the fly. Almost nothing is hard-coded; prompts, tools, and behavior all live in editable files, and any agent can spawn subordinate agents to break a task into focused sub-tasks. It is model-agnostic (OpenAI, Anthropic, and Google models, plus local models via Ollama), extensible through MCP, A2A, and a 100+ community plugin hub, and runs self-hosted so teams keep full control over data and credentials. First released in 2024 by Jan Tomasek and now past 18,000 GitHub stars, it targets developers, researchers, and technical teams who want a transparent, fully customizable alternative to closed agent products.

Integrations

Model-agnostic: works with OpenAI, Anthropic, and Google models, local models via Ollama, and account-backed plans through OpenAI Codex OAuth. Extends through MCP servers, A2A connectors, and a Plugin Hub of 100+ community plugins, plus a built-in browser and SearXNG private search.

In practice

You hit a task no pre-built tool covers. Agent Zero writes and runs the code it needs inside its own Linux container, building the tool on the fly instead of waiting for a vendor to add a feature.

A job is too big for one agent to hold in its head. Agent Zero spawns subordinate agents, each taking a focused sub-task, and coordinates them back into one result.

You can't send company data to someone else's servers. Agent Zero runs self-hosted in a Docker container you control, so prompts, tools, and credentials stay on your own infrastructure.

Integrations & Tool CallingUses the operating system as its tool, writes and runs code, creates new tools on the fly, connects to external tools through the Model Context Protocol, and installs from a hub of more than one hundred community plugins, broad and dynamic tool calling.	Full
Workflow OrchestrationRuns a hierarchical multi agent architecture where a primary agent spawns subordinate agents, each in its own isolated Docker sandbox, and delegates subtasks to them, genuine autonomous multi agent orchestration.	Full
Knowledge Grounding & RAGShips a self hosted search engine and a knowledge store with recall so agents can research and reference material, real retrieval, though grounded citation of every claim is not the headline of the product.	Partial
Human Oversight & GuardrailsIsolates every agent in a Docker sandbox, manages secrets, scans plugins before install, and offers Time Travel snapshots to inspect diffs and revert workspace state, real containment and recovery, though without a formal approval or step limit enforcement engine.	Partial
Security, Identity & GovernanceRuns fully self hosted in Docker with local models and a private self hosted search so data does not leave the machine, and includes secrets management, real data residency, though without published certifications, single sign on, or role based access controls.	Partial
Observability & AuditabilityExposes the agent reasoning and acting trajectory transparently, keeps browser screenshots of important steps, and provides a memory dashboard and Time Travel diff inspection, real process visibility, though not a full tracing and metrics platform.	Partial
Memory & State PersistenceProvides persistent memory that maintains state across sessions with automatic consolidation, filtered recall, and a memory dashboard, so agents track completed work and learn from past successes and failures, a first class memory system.	Full
Deployment & Data ResidencyIs open source under a permissive license and runs entirely self hosted in a Docker container, on a desktop launcher, or as a remote instance, and works with local models through Ollama for private offline operation, real self hosting and data residency.	Full
Prebuilt Agents, Templates & PacksShips a browsable Plugin Hub of community plugins and a Skills system for wrapping custom tools and extensions, real reusable packs and scaffolding, though these are capability plugins rather than a marketplace of ready made agents.	Partial
Triggers & Channel CoverageCan be driven through a web interface, a desktop application, a command line, an application programming interface, and a Model Context Protocol server, multiple user invoked channels, though without documented scheduled or external event triggers.	Partial
Model Flexibility & RoutingIs provider agnostic across OpenAI, Anthropic, xAI Grok, Google, OpenRouter, GitHub Copilot, and local models through Ollama, and lets you assign different models to different agent roles, genuine multi provider and role based model selection.	Full
APIs, SDKs & MCP ExtensibilityIs open source and built for extension through a prompt driven design, a plugin and Skills system, a command line, and a streamable Model Context Protocol server that exposes its capabilities to other tools, a comprehensive extensibility surface.	Full
Testing, Debugging & OptimizationExecutes, tests, and iterates on its own code and adapts and retries autonomously when errors occur, a real self correcting loop, though it does not ship a dedicated testing or evaluation engine for agents.	Partial
Browser & Computer UseGives every agent a full Linux system with shell, code execution, and a Playwright driven browser that can open pages, click, type, upload files, and take screenshots, positioned as an open alternative to computer use agents, genuine browser and computer control as a core capability.
