// how it works

How it works

  1. Clarify your goal

    Decide the first concrete outcome you want from it, so you can pick the right example, template or mode instead of exploring everything at once.

  2. Get the project

    Clone the repository (or install the published package) and skim its README quick start for the requirements for your platform.

  3. Install and configure

    Run the documented install step and set any required configuration — such as provider keys, data sources or local services — before the first run.

  4. Run your first task

    Execute the smallest documented example end to end, confirm the output is what you expected, then adapt it to your real data or workflow.

// features

Why people love it

Automatic workflow generation

Describe a goal and EvoAgentX generates a multi-agent workflow to execute it.

Self-evolution algorithms

Built-in evolution algorithms iteratively improve agents and workflows, with published results in the README.

Tool-enabled workflows

Agents can be given toolkits such as a command-line file-operations toolkit during generation.

Human-in-the-loop

Interceptor agents can approve or reject sensitive actions (for example an email send) mid-workflow.

Built-in tools summary

A catalogue of ready tools ships with the framework for common agent tasks.

Ready applications

Worked examples include a financial information workflow and an arXiv research summariser.

// run it

Run it yourself

  1. Clone the repository

    Get the source so you can inspect, configure and run it locally.

    git clone https://github.com/ANative-Lab/EvoAgentX.git
    cd EvoAgentX
  2. Install EvoAgentX

    Install from PyPI (or in development mode from source).

    pip install evoagentx
  3. Configure your LLM

    Set your provider key and define an LLM configuration in code, as the README shows.

    export OPENAI_API_KEY=your-key  # see README LLM Configuration

Questions, answered

Who maintains EvoAgentX?

It is maintained by ANative-Lab on GitHub (ANative-Lab/EvoAgentX), where the source, issues and releases live.

Is it free to use?

Yes — it is free and open source under the MIT licence, which permits use, modification and redistribution, including commercially, with attribution.

Does it need a paid API key?

Yes — EvoAgentX drives external LLMs, so you supply a provider key such as OPENAI_API_KEY; model usage is billed by that provider.

How does it compare to static multi-agent frameworks such as CrewAI or AutoGen?

Compared with static multi-agent frameworks such as CrewAI or AutoGen, EvoAgentX's distinguishing focus is: evoAgentX — a framework for building self-evolving ecosystems of AI agents. Pick it when that focus matches your need; the alternative may suit you better if its broader or different scope is the priority.

How do I get started?

Clone https://github.com/ANative-Lab/EvoAgentX (or install its published package), follow the README quick start to install and configure it, then run the smallest documented example — the Run section on this page mirrors those steps.
