// how it works

How it works

  1. Pick a framework

    Application frameworks, agent runtimes, or voice stacks — choose by whether you are building apps, automations, or realtime voice.

  2. Install the SDK

    Python or TypeScript packages install with one command; most include quickstart templates.

  3. Define tools and memory

    Give the agent functions it can call and a memory layer so it stays coherent across sessions.

  4. Run and observe

    Launch the agent, watch its tool calls and reasoning traces, and iterate on prompts and tools.

// features

Why people love it

Tool use & function calling

Agents act on the world: APIs, databases, browsers, and shell commands.

Multi-agent orchestration

Crews and graphs of specialized agents collaborating on complex tasks.

Memory systems

Short and long-term memory so agents improve across sessions.

Observability

Traces of every decision and tool call — essential for debugging.

Voice & realtime

Low-latency stacks for conversational voice agents.

Model agnostic

Swap underlying LLMs without rewriting your agent logic.

Questions, answered

Framework or finished agent?

Frameworks build your own; some repos here ship ready-made agents you can run directly.

Do agents need big models?

Tool-calling quality matters more than raw size — strong mid-size models work well.

Who maintains Eliza?

It is an open-source project at elizaOS/eliza with 5,774 forks. Check the repo's contributors and recent commits to see how active maintenance is.

How do I keep agents safe?

Sandbox tool access, confirm destructive actions, and review traces — treat agents like junior employees with supervision.

What does it cost to run?

Self-hosted frameworks are free; you pay only for model inference (local or API).

Where do I start?

A quickstart template in the framework's docs — most get a first agent running in minutes.
