Overview

OpenFang reads its configuration from a single TOML file:

~/.openfang/config.toml

On Windows, ~ resolves to C:\Users\<username>. If the home directory cannot be determined, the system temp directory is used as a fallback.

The home directory is resolved with the following priority:

OPENFANG_HOME environment variable (e.g. OPENFANG_HOME=/data in the official Docker image).
~/.openfang (default).

So inside the Docker container the config file must live at /data/config.toml (because the image sets ENV OPENFANG_HOME=/data). Placing it anywhere else (for example /opt/openfang/config.toml) will be silently ignored.

Key behaviors:

Every struct in the configuration uses #[serde(default)], which means all fields are optional. Omitted fields receive their documented default values.
Channel sections ([channels.telegram], [channels.discord], etc.) are Option<T> -- when absent, the channel adapter is disabled. Including the section header (even empty) enables the adapter with defaults.
Secrets are never stored in config.toml directly. Instead, fields like api_key_env and bot_token_env hold the name of an environment variable that contains the actual secret. This prevents accidental exposure in version control.
Sensitive fields (api_key, shared_secret) are automatically redacted in debug output and logs.

Minimal Configuration

The simplest working configuration only needs an LLM provider API key set as an environment variable. With no config file at all, OpenFang boots with Anthropic as the default provider:

toml

# ~/.openfang/config.toml
# Minimal: just override the model if you want something other than defaults.
# Set ANTHROPIC_API_KEY in your environment.

[default_model]
provider = "anthropic"
model = "claude-sonnet-4-20250514"
api_key_env = "ANTHROPIC_API_KEY"

Or to use a local Ollama instance with no API key:

toml

[default_model]
provider = "ollama"
model = "llama3.2:latest"
base_url = "http://localhost:11434"
api_key_env = ""

Section Reference

Top-Level Fields

These fields sit at the root of config.toml (not inside any [section]).

Field	Type	Default	Description
`home_dir`	path	`~/.openfang`	OpenFang home directory. Stores config, agents, skills.
`data_dir`	path	`~/.openfang/data`	Directory for SQLite databases and persistent data.
`log_level`	string	`"info"`	Log verbosity. One of: `trace`, `debug`, `info`, `warn`, `error`.
`api_listen`	string	`"127.0.0.1:50051"`	Bind address for the HTTP/WebSocket/SSE API server. Use `0.0.0.0:<port>` to accept connections from outside the host (LAN, Docker, remote clients). See Exposing the Dashboard below before doing so. Can be overridden at runtime with the `OPENFANG_LISTEN` environment variable.
`network_enabled`	bool	`false`	Enable the OFP peer-to-peer network layer.
`api_key`	string	`""` (empty)	API authentication key. When set, all endpoints except `/api/health` require `Authorization: Bearer <key>`. Empty means unauthenticated (local development only).
`mode`	string	`"default"`	Kernel operating mode. See below.
`language`	string	`"en"`	Language/locale code for CLI output and system messages.
`usage_footer`	string	`"full"`	Controls usage info appended to responses. See below.

mode values:

Value	Behavior
`stable`	Conservative: no auto-updates, pinned models, frozen skill registry. Uses `FallbackDriver`.
`default`	Balanced: standard operation.
`dev`	Developer: experimental features enabled.

usage_footer values:

Value	Behavior
`off`	No usage information shown.
`tokens`	Show token counts only.
`cost`	Show estimated cost only.
`full`	Show both token counts and estimated cost (default).

Exposing the Dashboard

By default OpenFang binds the API and dashboard to 127.0.0.1 (loopback only) so the daemon is unreachable from anywhere except the local machine. To accept connections from your LAN, Docker host, or a remote client you must explicitly opt in to non-loopback binding.

Two ways to change the bind address:

Edit config.toml:
toml
```
api_listen = "0.0.0.0:4200"
```
Or set the OPENFANG_LISTEN environment variable (overrides config.toml):
bash
```
export OPENFANG_LISTEN=0.0.0.0:4200
```
The env var route is the recommended path for Docker because it does not require mounting a config file.

Docker example. The official image sets OPENFANG_HOME=/data and exposes port 4200. The simplest end-to-end setup is:

yaml

services:
  openfang:
    image: ghcr.io/rightnow-ai/openfang:latest
    ports:
      - "4200:4200"
    volumes:
      - openfang-data:/data
    environment:
      - OPENFANG_LISTEN=0.0.0.0:4200          # required: bind to all interfaces inside the container
      - OPENFANG_API_KEY=${OPENFANG_API_KEY}  # strongly recommended when exposing
      - ANTHROPIC_API_KEY=${ANTHROPIC_API_KEY:-}
volumes:
  openfang-data:

If you prefer mounting config.toml, the file must live at /data/config.toml inside the container (because of OPENFANG_HOME=/data). Placing it at /opt/openfang/config.toml or any other path will not be picked up. The port in api_listen must also match the port published in ports: — the example config in openfang.toml.example ships with port 50051 to be safe; change it to 4200 (or whatever port you publish) when running in Docker.

Security warning. Once you bind to a non-loopback address, anyone reachable at that address can talk to the API. OpenFang's middleware enforces a fail-closed default:

If api_key is empty AND dashboard auth is disabled AND the bind address is not loopback, all non-loopback requests are rejected with 401 Unauthorized.
To run in this configuration anyway (not recommended), set OPENFANG_ALLOW_NO_AUTH=1. This will be loudly logged.

The supported ways to expose the dashboard safely:

Set api_key = "..." in config.toml (or OPENFANG_API_KEY=...) and send Authorization: Bearer <key> on every request.
Or enable the [auth] section to require username/password login on the dashboard UI.
Or keep api_listen on 127.0.0.1 and reach the dashboard through an SSH tunnel or reverse proxy that handles authentication for you.

`[default_model]`

Configures the primary LLM provider used when agents do not specify their own model.

toml

`model`	string	`"claude-sonnet-4-20250514"`	Model identifier. Aliases like `sonnet`, `haiku`, `gpt-4o`, `gemini-flash` are resolved by the model catalog.
`api_key_env`	string	`"ANTHROPIC_API_KEY"`	Name of the environment variable holding the API key. The actual key is read from this env var at runtime, never stored in config.
`base_url`	string or null	`null`	Override the API base URL. Useful for proxies or self-hosted endpoints. When `null`, the provider's default URL from the model catalog is used.

`[memory]`

Configures the SQLite-backed memory substrate, including vector embeddings and memory decay.

consolidation_threshold = 10000
decay_rate = 0.1

Field	Type	Default	Description
`sqlite_path`	path or null	`null`	Explicit path to the SQLite database file. When `null`, defaults to `{data_dir}/openfang.db`.
`embedding_model`	string	`"all-MiniLM-L6-v2"`	Model name used for generating vector embeddings for semantic memory search.
`consolidation_threshold`	u64	`10000`	Number of stored memories before automatic consolidation is triggered to merge and prune old entries.
`decay_rate`	f32	`0.1`	Memory confidence decay rate. `0.0` = no decay (memories never fade), `1.0` = aggressive decay. Values between 0.0 and 1.0.

`[network]`

Field	Type	Default	Description
`listen_addresses`	list of strings	`["/ip4/0.0.0.0/tcp/0"]`	libp2p multiaddresses to listen on. Port `0` means auto-assign.
`bootstrap_peers`	list of strings	`[]`	Multiaddresses of bootstrap peers for DHT discovery.
`mdns_enabled`	bool	`true`	Enable mDNS for automatic local network peer discovery.
`max_peers`	u32	`50`	Maximum number of simultaneously connected peers.
`shared_secret`	string	`""` (empty)	Pre-shared secret for OFP HMAC-SHA256 mutual authentication. Required when `network_enabled = true`. Both sides must use the same secret. Redacted in logs.

`[auth]`

Configures dashboard login with username/password authentication. Disabled by default.

toml

[auth]
enabled = true

`session_ttl_hours`	u64	`168` (7 days)	Session token lifetime in hours.

Generating a password hash:

bash

openfang auth hash-password

This prompts for a password and outputs an Argon2id PHC string to paste into config.toml.

Breaking change (v0.5.0): Password hashes must be in Argon2id format. Older SHA256 hex hashes from versions prior to v0.5.0 are no longer accepted. Re-run openfang auth hash-password to generate a new hash.

For web search providers, the validator checks:

Provider	Env var checked
`brave`	`web.brave.api_key_env`
`tavily`	`web.tavily.api_key_env`
`perplexity`	`web.perplexity.api_key_env`
`duck_duck_go`	(no check -- no API key needed)
`auto`	(no check -- cascading fallback handles missing keys)

What is NOT validated

The api_key_env in [default_model] is not checked by validate(). Missing LLM keys cause errors at runtime when the driver is first used.
The shared_secret in [network] is not validated against network_enabled. If networking is enabled with an empty secret, authentication will fail at connection time.
MCP server configurations are not validated at config load time. Connection errors surface during the background MCP connect phase.
Agent manifests have their own separate validation.

Some subsystems have their own configuration that is not part of config.toml but is worth noting:

Session Compaction (runtime)

Configured internally via CompactionConfig (not currently exposed in config.toml):

Field	Default	Description
`threshold`	`80`	Compact when session message count exceeds this.
`keep_recent`	`20`	Number of recent messages preserved verbatim after compaction.
`max_summary_tokens`	`1024`	Maximum tokens for the LLM summary of compacted messages.

WASM Sandbox (runtime)

Configured internally via SandboxConfig (not currently exposed in config.toml):

Field	Default	Description
`fuel_limit`	`1000000`	Maximum CPU instruction budget. `0` = unlimited.
`max_memory_bytes`	`16777216` (16 MB)	Maximum WASM linear memory.
`timeout_secs`	`null` (30s fallback)	Wall-clock timeout for epoch-based interruption.

Model Routing (per-agent manifest)

Configured in agent manifests via ModelRoutingConfig:

Field	Default	Description
`simple_model`	`"claude-haiku-4-5-20251001"`	Model for simple queries.
`medium_model`	`"claude-sonnet-4-20250514"`	Model for medium-complexity queries.
`complex_model`	`"claude-sonnet-4-20250514"`	Model for complex queries.
`simple_threshold`	`100`	Token count below which a query is classified as simple.
`complex_threshold`	`500`	Token count above which a query is classified as complex.

Heartbeat Monitor

Global heartbeat settings in [heartbeat]:

toml

[heartbeat]
# Seconds of inactivity before a reactive agent is marked as unresponsive.
# Increase this if you have hands that sit idle between infrequent requests.
# Default: 180
default_timeout_secs = 300

Field	Default	Description
`default_timeout_secs`	`180`	Seconds of inactivity before marking an agent as unresponsive. Per-agent `heartbeat_interval_secs` in autonomous config overrides this.

Autonomous Guardrails (per-agent manifest)

Configured in agent manifests via AutonomousConfig:

Field	Default	Description
`quiet_hours`	`null`	Cron expression for quiet hours (agent pauses during this window).
`max_iterations`	`50`	Maximum tool-use iterations per invocation.
`max_restarts`	`10`	Maximum automatic restarts before permanent stop.
`heartbeat_interval_secs`	`30`	Seconds between heartbeat health checks.
`heartbeat_channel`	`null`	Channel to send heartbeat status to (e.g., `"telegram"`).
