## Choose when

### Choose agent-zero if…

- agent-zero is primarily Python; sim is TypeScript.
- License: agent-zero is Other, sim is Apache-2.0.
- Both Agent Zero and sim aim to support the development, deployment, and orchestration of AI agents, offering somewhat overlapping functionalities.
- Tags unique to agent-zero: assistant, zero, linux, autonomous.
- You require a full-fledged Linux desktop environment for your AI agent to operate in.

### Choose sim if…

- sim is primarily TypeScript; agent-zero is Python.
- License: sim is Apache-2.0, agent-zero is Other.
- Both Agent Zero and sim aim to support the development, deployment, and orchestration of AI agents, offering somewhat overlapping functionalities.
- Tags unique to sim: agents, artificial-intelligence, aiagents, agentic-workflow.
- When you need to connect over a thousand different services and major language models as part of your AI agents’ workflows.

## When NOT to use agent-zero

- If you are seeking lightweight solutions that do not involve a full Linux system within a container.
- When you prefer to manage AI agents without a desktop environment or plugin extensibility.
- In scenarios where Docker is not an option or when running on systems with significant resource constraints.

## When NOT to use sim

- If you need a solution with less integrations support; Sim is more suited for projects requiring access to over a thousand services and major LLMs.
- When your team prefers text-based or script-driven agent development, as Sim emphasizes visual workflow building, which might not fit teams accustomed to coding-centric methodologies.
