---

Eliza uses a primary JSON5 config file for runtime and bootstrap settings.
This page documents the config file, environment variable overrides, and the
canonical runtime routing fields that now drive hosting and provider selection.

## Config File Location

By default, Eliza stores its configuration at:

```
~/.eliza/eliza.json
```

<Info>
The config directory is `~/.eliza` and the config file is `eliza.json` inside it. The CLI binary is `eliza` and the npm package name is `elizaai`.
</Info>

### Overriding the Location

Two environment variables control where Eliza looks for configuration:

| Variable | Purpose | Default |
|----------|---------|---------|
| `ELIZA_STATE_DIR` | Override the entire state directory | `~/.eliza` |
| `ELIZA_CONFIG_PATH` | Override the config file path directly | `~/.eliza/eliza.json` |

`ELIZA_CONFIG_PATH` takes precedence over `ELIZA_STATE_DIR`. Both support `~` expansion for the home directory. For backwards compatibility, the legacy names `MILADY_STATE_DIR` and `MILADY_CONFIG_PATH` are also accepted as fallbacks.

```bash
# Use a custom state directory (config lives at /opt/eliza/eliza.json)
ELIZA_STATE_DIR=/opt/eliza eliza start

# Point to a specific config file
ELIZA_CONFIG_PATH=~/projects/bot/config.json5 eliza start
```

### Other State Directory Paths

The state directory also contains:

| Path | Purpose |
|------|---------|
| `~/.eliza/models/` | Cached model provider lists (per-provider JSON files) |
| `~/.eliza/credentials/` | OAuth credentials (overridable via `ELIZA_OAUTH_DIR`) |
| `~/.eliza/credentials/oauth.json` | OAuth token storage |

## Canonical Runtime Routing

Eliza's saved runtime topology is no longer inferred from a single
`connection` blob, and the root `connection` field is no longer part of the
persisted config schema. The canonical persisted fields are:

| Field | Purpose |
|------|---------|
| `deploymentTarget` | Where the active server runs: `local`, `cloud`, or `remote` |
| `linkedAccounts` | Which provider or cloud accounts are available to that server |
| `serviceRouting` | Which backend handles each capability (`llmText`, `tts`, `media`, `embeddings`, `rpc`) |

```json5
{
  deploymentTarget: {
    runtime: "cloud",
    provider: "elizacloud",
  },
  linkedAccounts: {
    elizacloud: {
      status: "linked",
      source: "oauth",
    },
  },
  serviceRouting: {
    llmText: {
      backend: "anthropic",
      transport: "direct",
      primaryModel: "anthropic/claude-sonnet-4.6",
    },
    tts: {
      backend: "elizacloud",
      transport: "cloud-proxy",
      accountId: "elizacloud",
    },
  },
}
```

That means a server can be hosted on Eliza Cloud while still using Anthropic,
OpenAI, OpenRouter, or a local model for chat inference.

## File Format

The config file supports **JSON5** syntax, which allows:

- Comments (`//` and `/* */`)
- Trailing commas
- Unquoted keys
- Single-quoted strings
- Multiline strings

```json5
{
  // Agent configuration
  agent: { name: "mila" },

  // API keys (prefer .env for secrets)
  env: {
    ANTHROPIC_API_KEY: "<ANTHROPIC_API_KEY>",
  },
}
```

### `$include` Directive

Configs support modular composition via `$include`. Included files are deep-merged in order, with later values overriding earlier ones.

```json5
{
  "$include": "./base.json5",
  // Local overrides merged on top
  agents: { list: [{ id: "custom", name: "Custom Agent" }] }
}
```

```json5
// Array form: merge multiple base configs
{
  "$include": ["./base.json5", "./connectors.json5"],
  env: { MY_KEY: "override" }
}
```

Includes support up to 10 levels of nesting. Circular includes are detected and rejected.

### Environment Variables in Config

Eliza loads environment variables from two sources:

<Tabs>
  <Tab title="Inline in config (env section)">
    Set variables directly in `eliza.json`. They are applied to the process environment if not already set:

    ```json5
    {
      env: {
        ANTHROPIC_API_KEY: "<ANTHROPIC_API_KEY>",
        OPENAI_API_KEY: "<OPENAI_API_KEY>",
        // Structured form under vars:
        vars: {
          BRAVE_API_KEY: "<BRAVE_API_KEY>",
        },
      },
    }
    ```

    Both top-level string values and values under `env.vars` are merged into the process environment.
  </Tab>
  <Tab title="Shell environment import">
    Opt-in to importing variables from your login shell:

    ```json5
    {
      env: {
        shellEnv: {
          enabled: true,
          timeoutMs: 15000, // default: 15s
        },
      },
    }
    ```

    This runs `$SHELL -l -c 'env -0'` and imports missing variables.
  </Tab>
</Tabs>

<Warning>
The config file is written with mode `0o600` (owner read+write only) because the `env` section may contain API keys. Keep secrets in the `env` section or use a separate `~/.eliza/.env` file.
</Warning>

## Top-Level Structure

Here is every top-level key in `ElizaConfig`:

```json5
{
  meta: {},           // Config metadata (version tracking)
  auth: {},           // Auth profiles and provider credentials
  env: {},            // Environment variables and shell env import

  features: {},       // Feature flags (auto-enable plugins)
  customActions: [],  // User-defined custom actions
}
```

## Agent Configuration

Agents are defined under `agents.list`. The `agents.defaults` section provides shared defaults.

```json5
{
  agents: {
    defaults: {
      model: { primary: "anthropic/claude-sonnet-4.6" },
      workspace: "~/projects/my-agent",
      thinkingDefault: "medium",
      timeoutSeconds: 120,
      maxConcurrent: 1,
    },
    list: [
      {
        id: "mila",
        default: true,
        name: "Mila",
        model: "anthropic/claude-opus-4.7",
        workspace: "~/projects/mila-workspace",
        // Personality (set during onboarding)
        bio: ["A helpful AI assistant"],
        system: "You are Mila, a thoughtful assistant.",
        style: { all: ["concise", "friendly"] },
        adjectives: ["helpful", "creative"],
        // Identity for display
        identity: { name: "Mila" },
        // Per-agent tool overrides
        tools: {
          profile: "standard",
          exec: { security: "allowlist" },
        },
        // Per-agent sandbox settings
        sandbox: {
          mode: "non-main",
          workspaceAccess: "ro",
          scope: "session",
        },
      },
    ],
  },
}
```

### Key Agent Fields

| Field | Type | Description |
|-------|------|-------------|
| `id` | `string` | Unique agent identifier (required) |
| `default` | `boolean` | Mark as the default agent |
| `name` | `string` | Display name |
| `model` | `string \| { primary, fallbacks[] }` | Model selection with optional fallbacks |
| `workspace` | `string` | Working directory for agent runs |
| `skills` | `string[]` | Allowlist of skills (omit for all, empty for none) |
| `bio` | `string[]` | Agent bio lines |
| `system` | `string` | System prompt |
| `style` | `{ all?, chat?, post? }` | Communication style rules |

| `sandbox` | `object` | Sandbox isolation settings |
| `heartbeat` | `object` | Periodic background heartbeat runs |
| `memorySearch` | `MemorySearchConfig` | Per-agent memory search overrides |

### Agent Defaults

`agents.defaults` controls global behavior for all agents:

```json5
{
  agents: {
    defaults: {
      model: { primary: "anthropic/claude-sonnet-4.6", fallbacks: ["openai/gpt-5"] },
      workspace: "~/agent-workspace",
      thinkingDefault: "medium",       // off | minimal | low | medium | high | xhigh
      verboseDefault: "off",           // off | on | full
      elevatedDefault: "off",          // off | on | ask | full
      blockStreamingDefault: "off",    // off | on
      timeoutSeconds: 120,
      maxConcurrent: 1,
      userTimezone: "America/New_York",
      timeFormat: "auto",              // auto | 12 | 24
      // Heartbeat (periodic background runs)
      heartbeat: {
        every: "30m",
        model: "anthropic/claude-haiku-4-5-20251001",
        target: "last",
      },
      // Sandbox defaults
      sandbox: {
        mode: "non-main",
        workspaceAccess: "ro",
        scope: "session",
        docker: {
          image: "node:20-slim",
          network: "none",
        },
      },
      // Sub-agent defaults
      subagents: {
        maxConcurrent: 1,
        archiveAfterMinutes: 60,
        model: "anthropic/claude-haiku-4-5-20251001",
      },
    },
  },
}
```

## Model Configuration

### Selecting Models

The simplest way to configure models is through `agents.defaults.model`:

```json5
{
  agents: {
    defaults: {
      model: {
        primary: "anthropic/claude-sonnet-4.6",
        fallbacks: ["openai/gpt-5", "groq/openai/gpt-oss-120b"],
      },
    },
  },
}
```

The `models` section at the top level lets you define custom providers, override model definitions, and configure Bedrock:

```json5
{
  models: {
    // "merge" (default) adds to built-in providers; "replace" uses only what's defined here
    mode: "merge",
    // Quick model aliases set during onboarding
    small: "claude-haiku",
    large: "claude-sonnet-4-6",
    // Custom or self-hosted providers
    providers: {
      "my-provider": {
        baseUrl: "https://api.example.com/v1",
        apiKey: "<OPENAI_API_KEY>",
        api: "openai-completions",   // openai-completions | openai-responses | anthropic-messages | google-generative-ai | bedrock-converse-stream
        models: [
          {
            id: "my-model-v1",
            name: "My Model v1",
            reasoning: false,
            input: ["text", "image"],
            cost: { input: 3, output: 15, cacheRead: 0.3, cacheWrite: 3.75 },
            contextWindow: 200000,
            maxTokens: 8192,
          },
        ],
      },
    },
    // AWS Bedrock model discovery
    bedrockDiscovery: {
      enabled: true,
      region: "us-east-1",
      providerFilter: ["anthropic", "meta"],
      refreshInterval: 3600,
    },
  },
}
```

### Model Provider Auth Modes

Each custom provider can specify an authentication mode:

| Mode | Description |
|------|-------------|
| `api-key` | Static API key (default) |
| `aws-sdk` | AWS SDK credentials (for Bedrock) |
| `oauth` | Refreshable OAuth credentials |
| `token` | Static bearer token |

## Plugin Configuration

Plugins extend Eliza with connectors, providers, and feature capabilities.

```json5
{
  plugins: {
    enabled: true,             // Master switch
    allow: ["telegram", "anthropic"],  // Allowlist (plugin short ids)
    deny: ["experimental"],    // Denylist (takes priority over allow)
    // Per-plugin configuration
    entries: {
      telegram: {
        enabled: true,
        config: { /* plugin-specific */ },
      },
      browser: {
        enabled: false,        // Disable a specific plugin
      },
    },
    // Plugin loading
    load: {
      paths: ["/path/to/custom-plugin"],  // Additional plugin paths
    },
    // Slot assignments
    slots: {
      memory: "builtin",      // Which plugin owns the memory slot ("none" disables)
    },
  },
}
```

### Plugin Auto-Enable

Eliza automatically enables plugins based on your configuration. You do not need to manually add plugins to the allowlist in most cases.

**Connector plugins** are auto-enabled when a connector is configured with credentials. Connectors marked with * are upstream elizaOS plugins not included in the Eliza bundled registry — they must be installed first (`eliza plugins install <package>`):

| Connector | Plugin | Auto-Enable Trigger |
|-----------|--------|---------------------|
| `telegram` | `@elizaos/plugin-telegram` | `connectors.telegram.botToken` |
| `discord` | `@elizaos/plugin-discord` | `connectors.discord.token` (or `botToken`/`apiKey`) |
| `slack` | `@elizaos/plugin-slack` | `connectors.slack.botToken` |
| `twitter` * | `@elizaos/plugin-x` | `connectors.twitter.apiKey` |
| `whatsapp` | `@elizaos/plugin-whatsapp` | `connectors.whatsapp.authDir` (or `authState`, `sessionPath`, or `accounts` with `authDir`) |
| `signal` | `@elizaos/plugin-signal` | `connectors.signal.account` (or `httpUrl`, `httpHost`, `httpPort`, `cliPath`, or `accounts` with enabled entries) |
| `farcaster` | `@elizaos/plugin-farcaster` | `connectors.farcaster.apiKey` (or `token`/`botToken`) |
| `matrix` | `@elizaos/plugin-matrix` | `connectors.matrix.token` (or `botToken`/`apiKey`) |
| `nostr` | `@elizaos/plugin-nostr` | `connectors.nostr.token` (or `botToken`/`apiKey`); actual auth uses `NOSTR_PRIVATE_KEY` env var |
| `msteams` | `@elizaos/plugin-msteams` | `connectors.msteams.botToken` (or `token`/`apiKey`) |
| `googlechat` | `@elizaos/plugin-google-chat` | `connectors.googlechat.apiKey` (or `token`/`botToken`) |
| `imessage` | `@elizaos/plugin-imessage` | `connectors.imessage.cliPath` |
| `lens` | `@elizaos/plugin-lens` | `connectors.lens.apiKey` (or `token`/`botToken`) |
| `mattermost` | `@elizaos/plugin-mattermost` | `connectors.mattermost.botToken` (or `token`/`apiKey`) |
| `feishu` | `@elizaos/plugin-feishu` | `connectors.feishu.apiKey` (or `token`/`botToken`) |
| `blooio` | `@elizaos/plugin-blooio` | `connectors.blooio.apiKey` (or `token`/`botToken`) |
| `twitch` | `@elizaos/plugin-twitch` | `connectors.twitch.accessToken` or `clientId` or `enabled: true` |
| `wechat` | `@elizaos/plugin-wechat` | `connectors.wechat.apiKey` (or `accounts` with `apiKey`) |

**Provider plugins** are auto-enabled when the corresponding API key environment variable is set:

| Env Variable | Plugin |
|--------------|--------|
| `ANTHROPIC_API_KEY` / `CLAUDE_API_KEY` | `@elizaos/plugin-anthropic` |
| `OPENAI_API_KEY` | `@elizaos/plugin-openai` |
| `AI_GATEWAY_API_KEY` / `AIGATEWAY_API_KEY` | `@elizaos/plugin-vercel-ai-gateway` |
| `GOOGLE_API_KEY` / `GOOGLE_GENERATIVE_AI_API_KEY` | `@elizaos/plugin-google-genai` |
| `GOOGLE_CLOUD_API_KEY` | `@elizaos/plugin-google-antigravity` |
| `GROQ_API_KEY` | `@elizaos/plugin-groq` |
| `XAI_API_KEY` / `GROK_API_KEY` | `@elizaos/plugin-xai` |
| `OPENROUTER_API_KEY` | `@elizaos/plugin-openrouter` |
| `OLLAMA_BASE_URL` | `@elizaos/plugin-ollama` |
| `ZAI_API_KEY` | `@elizaos/plugin-zai` |
| `DEEPSEEK_API_KEY` | `@elizaos/plugin-deepseek` |
| `TOGETHER_API_KEY` | `@elizaos/plugin-together` |
| `MISTRAL_API_KEY` | `@elizaos/plugin-mistral` |
| `COHERE_API_KEY` | `@elizaos/plugin-cohere` |
| `PERPLEXITY_API_KEY` | `@elizaos/plugin-perplexity` |
| `ELIZAOS_CLOUD_API_KEY` / `ELIZAOS_CLOUD_ENABLED` | `@elizaos/plugin-elizacloud` |
| `CUA_API_KEY` / `CUA_HOST` | `@elizaos/plugin-cua` |
| `OBSIDIAN_VAULT_PATH` | `@elizaos/plugin-obsidian` |
| `REPOPROMPT_CLI_PATH` | `@elizaos/plugin-repoprompt` |

**Feature plugins** are auto-enabled via the `features` flag map:

```json5
{
  features: {
    browser: true,
    cron: true,
    shell: true,
    imageGen: true,
    tts: true,
    webhooks: true,
    computeruse: true,
  },
}
```

| Feature Flag | Plugin |
|-------------|--------|
| `browser` | `@elizaos/plugin-browser` |
| `cua` | `@elizaos/plugin-cua` |
| `obsidian` | `@elizaos/plugin-obsidian` |
| `shell` | `@elizaos/plugin-shell` |
| `imageGen` | `@elizaos/plugin-image-generation` |
| `tts` | `@elizaos/plugin-tts` |
| `stt` | `@elizaos/plugin-stt` |
| `agentSkills` | `@elizaos/plugin-agent-skills` |
| `commands` | `@elizaos/plugin-commands` |
| `diagnosticsOtel` | `@elizaos/plugin-diagnostics-otel` |
| `webhooks` | `@elizaos/plugin-webhooks` |
| `gmailWatch` | `@elizaos/plugin-gmail-watch` |
| `experience` | built-in advanced capabilities |
| `form` | built-in advanced capabilities |
| `x402` | `@elizaos/plugin-x402` |
| `fal` | `@elizaos/plugin-fal` |
| `suno` | `@elizaos/plugin-suno` |
| `vision` | `@elizaos/plugin-vision` |
| `computeruse` | `@elizaos/plugin-computeruse` |
| `repoprompt` | `@elizaos/plugin-repoprompt` |

<Info>
The `vision`, `fal`, and `suno` plugins are also auto-enabled when their respective `media.*` config sections are configured (e.g., `media.vision.provider` is set, or `media.image.provider: "fal"` with `mode: "own-key"`). Webhook plugins auto-enable when `hooks.token` is set. Gmail watch auto-enables when `hooks.gmail.account` is set.
</Info>

<Tip>
You can always force-disable any auto-enabled plugin by setting `plugins.entries.<id>.enabled: false`. The denylist takes priority over all auto-enable logic.
</Tip>

## Connectors (Messaging Channels)

Connectors integrate Eliza with messaging platforms. Configure them under `connectors`:

```json5
{
  connectors: {
    telegram: {
      enabled: true,
      botToken: "<TELEGRAM_BOT_TOKEN>",
      // Additional connector-specific options
    },
    discord: {
      enabled: true,
      token: "<DISCORD_BOT_TOKEN>",
    },
    slack: {
      enabled: true,
      botToken: "<SLACK_BOT_TOKEN>",
      appToken: "<SLACK_APP_TOKEN>",
    },
    whatsapp: {
      enabled: true,
      authDir: "~/.eliza/whatsapp-auth",
    },
  },
}
```

<Warning>
The `channels` key is deprecated. Use `connectors` instead. Both are supported during migration, but `connectors` takes precedence.
</Warning>

### Agent Bindings

Route specific conversations to specific agents using `bindings`:

```json5
{
  bindings: [
    {
      agentId: "support-bot",
      match: {
        channel: "telegram",
        peer: { kind: "group", id: "-100123456" },
      },
    },
    {
      agentId: "dm-agent",
      match: {
        channel: "discord",
        peer: { kind: "dm", id: "user-id" },
      },
    },
  ],
}
```

## Gateway Configuration

The gateway is the central server that handles WebSocket connections, HTTP API, and the Control UI.

```json5
{
  gateway: {
    port: 18789,                // Default: 18789
    mode: "local",              // "local" | "remote"
    bind: "loopback",           // "auto" | "lan" | "loopback" | "tailnet" | "custom"
    customBindHost: "10.0.0.5", // Only used when bind: "custom"
    // TLS configuration
    tls: {
      enabled: true,
      autoGenerate: true,       // Auto self-signed cert
      certPath: "/path/to/cert.pem",
      keyPath: "/path/to/key.pem",
    },
    // Authentication
    auth: {
      mode: "token",            // "token" | "password"
      token: "<API_TOKEN>",
      allowTailscale: false,
    },
    // Control UI (web dashboard)
    controlUi: {

## Environment Variables Reference

Key environment variables that affect Eliza behavior:

### Path Overrides

| Variable | Purpose |
|----------|---------|
| `ELIZA_STATE_DIR` | Override state directory (`~/.eliza`) |
| `ELIZA_CONFIG_PATH` | Override config file path directly |
| `ELIZA_OAUTH_DIR` | Override OAuth credentials directory |

### Ports and Networking

| Variable | Default | Purpose |
|----------|---------|---------|
| `ELIZA_API_PORT` | `31337` | API + WebSocket port. Used in dev mode (`bun run dev`) where the API and UI run on separate ports. In production (`eliza start`) the API is served on `ELIZA_PORT` instead |
| `ELIZA_PORT` | `2138` | Dashboard (Web UI) port. In production this port also serves the API. In dev mode this port is the Vite dev server only |
| `ELIZA_GATEWAY_PORT` | `18789` | Gateway port |
| `ELIZA_HOME_PORT` | `2142` | Home Dashboard port |
| `ELIZA_WECHAT_WEBHOOK_PORT` | `18790` | WeChat Webhook port |

```bash
# Custom ports
ELIZA_GATEWAY_PORT=19000 ELIZA_PORT=3000 eliza start
```

### Model Provider API Keys

| Variable | Provider |
|----------|----------|
| `ANTHROPIC_API_KEY` | Anthropic (Claude) |
| `OPENAI_API_KEY` | OpenAI (GPT) |
| `AI_GATEWAY_API_KEY` | Vercel AI Gateway |
| `GOOGLE_API_KEY` | Google Gemini |
| `GROQ_API_KEY` | Groq |
| `XAI_API_KEY` | xAI (Grok + Twitter/X) |
| `OPENROUTER_API_KEY` | OpenRouter (200+ models via one key) |
| `OLLAMA_BASE_URL` | Ollama (local) |

### Feature-Specific Variables

| Variable | Purpose |
|----------|---------|
| `BRAVE_API_KEY` | Brave Search (web search tool) |
| `FIRECRAWL_API_KEY` | Firecrawl (web fetch fallback) |
| `ELEVENLABS_API_KEY` | ElevenLabs (TTS and Talk mode) |
| `FAL_KEY` | FAL.ai (image/video generation) |

See the [Model Providers](/model-providers) page for a full list of supported providers.

## CLI Config Commands

Eliza provides CLI commands to inspect configuration without editing JSON directly:

```bash
# Configuration guidance (common env vars and usage)
eliza configure

# Read a config value (dot-notation)
eliza config get agents.defaults.model
eliza config get gateway.port

# Print the resolved config file path
eliza config path

# Display all config values grouped by section
eliza config show
eliza config show --all    # Include advanced/hidden fields
eliza config show --json   # Raw JSON output
```

To change values, edit `~/.eliza/eliza.json` directly (it supports JSON5 with comments).

<Tip>
Use `eliza configure` for a quick reference of common configuration options
and environment variables. For local bootstrap, run `eliza setup`, or edit
`~/.eliza/eliza.json` directly.
</Tip>
