Use this page for day-1 startup and day-2 operations of the Gateway service.

5-minute local startup

openclaw gateway --port 18789
# debug/trace mirrored to stdio
openclaw gateway --port 18789 --verbose
# force-kill listener on selected port, then start
openclaw gateway --force

openclaw gateway status
openclaw status
openclaw logs --follow

Healthy baseline: Runtime: running, Connectivity probe: ok, and a Capability line that matches what you expect. Use openclaw gateway status --require-rpc for read-scope RPC proof, not just reachability.

openclaw channels status --probe

With a reachable gateway this runs live per-account channel probes and optional audits. If the gateway is unreachable, the CLI falls back to config-only channel summaries.

Runtime model

• One always-on process for routing, control plane, and channel connections.
• Single multiplexed port for:
  • WebSocket control/RPC
  • HTTP APIs (/v1/models, /v1/embeddings, /v1/chat/completions, /v1/responses, /tools/invoke)
  • Plugin HTTP routes, such as optional /api/v1/admin/rpc
  • Control UI and hooks
• Default bind mode: loopback. Inside a detected container environment the effective default is auto (resolves to 0.0.0.0 for port-forwarding), unless Tailscale serve/funnel is active, which always forces loopback.
• Auth is required by default. Shared-secret setups use gateway.auth.token / gateway.auth.password (or OPENCLAW_GATEWAY_TOKEN / OPENCLAW_GATEWAY_PASSWORD), and non-loopback reverse-proxy setups can use gateway.auth.mode: "trusted-proxy".

OpenAI-compatible endpoints

OpenClaw's highest-leverage compatibility surface:

• GET /v1/models
• GET /v1/models/{id}
• POST /v1/embeddings
• POST /v1/chat/completions
• POST /v1/responses

Why this set matters:

• Most Open WebUI, LobeChat, and LibreChat integrations probe /v1/models first.
• Many RAG and memory pipelines expect /v1/embeddings.
• Agent-native clients increasingly prefer /v1/responses.

/v1/models is agent-first: it returns openclaw, openclaw/default, and openclaw/<agentId> for every configured agent. openclaw/default is the stable alias that always maps to the configured default agent. Send x-openclaw-model when you want a backend provider/model override; otherwise the selected agent's normal model and embedding setup stays in control.

All of these run on the main Gateway port and use the same trusted operator auth boundary as the rest of the Gateway HTTP API.

Admin HTTP RPC (POST /api/v1/admin/rpc) is a separate, default-off plugin route for host tooling that cannot use WebSocket RPC. See Admin HTTP RPC.

Port and bind precedence

Installed gateway services record the resolved --port in supervisor metadata. After changing gateway.port, run openclaw doctor --fix or openclaw gateway install --force so launchd/systemd/schtasks starts the process on the new port.

Gateway startup uses the same effective port and bind when it seeds local Control UI origins for non-loopback binds. For example, --bind lan --port 3000 seeds http://localhost:3000 and http://127.0.0.1:3000 before runtime validation runs. Add any remote browser origins, such as HTTPS proxy URLs, to gateway.controlUi.allowedOrigins explicitly.

Hot reload modes

Operator command set

openclaw gateway status
openclaw gateway status --deep   # adds a system-level service scan
openclaw gateway status --json
openclaw gateway install
openclaw gateway restart
openclaw gateway stop
openclaw secrets reload
openclaw logs --follow
openclaw doctor

gateway status --deep is for extra service discovery (LaunchDaemons/systemd system units/schtasks), not a deeper RPC health probe.

Multiple gateways (same host)

Most installs should run one gateway per machine. A single gateway can host multiple agents and channels. You only need multiple gateways when you intentionally want isolation or a rescue bot.

Useful checks:

openclaw gateway status --deep
openclaw gateway probe

What to expect:

• gateway status --deep can report Other gateway-like services detected (best effort) and print cleanup hints when stale launchd/systemd/schtasks installs are still around.
• gateway probe can warn about multiple reachable gateway identities when distinct gateways answer, or when OpenClaw cannot prove reachable targets are the same gateway. An SSH tunnel, proxy URL, or configured remote URL to the same gateway is one gateway with multiple transports, even when transport ports differ.
• If that is intentional, isolate ports, config/state, and workspace roots per gateway.

Checklist per instance:

• Unique gateway.port
• Unique OPENCLAW_CONFIG_PATH
• Unique OPENCLAW_STATE_DIR
• Unique agents.defaults.workspace

Example:

OPENCLAW_CONFIG_PATH=~/.openclaw/a.json OPENCLAW_STATE_DIR=~/.openclaw-a openclaw gateway --port 19001
OPENCLAW_CONFIG_PATH=~/.openclaw/b.json OPENCLAW_STATE_DIR=~/.openclaw-b openclaw gateway --port 19002

Detailed setup: /gateway/multiple-gateways.

Remote access

Preferred: Tailscale/VPN. Fallback: SSH tunnel.

ssh -N -L 18789:127.0.0.1:18789 user@gateway-host

Then connect clients locally to ws://127.0.0.1:18789.

See: Remote Gateway, Authentication, Tailscale.

Supervision and service lifecycle

Use supervised runs for production-like reliability.

openclaw gateway install
openclaw gateway status
openclaw gateway restart
openclaw gateway stop

Use openclaw gateway restart for restarts. Do not chain openclaw gateway stop and openclaw gateway start as a restart substitute.

On macOS, gateway stop uses launchctl bootout by default. This removes the LaunchAgent from the current boot session without persisting a disable, so KeepAlive auto-recovery still works after unexpected crashes and gateway start re-enables cleanly. To persistently suppress auto-respawn across reboots, pass --disable: openclaw gateway stop --disable.

LaunchAgent labels are ai.openclaw.gateway (default) or ai.openclaw.<profile> (named profile). openclaw doctor audits and repairs service config drift.

openclaw gateway install
systemctl --user enable --now openclaw-gateway[-<profile>].service
openclaw gateway status

For persistence after logout, enable lingering:

sudo loginctl enable-linger $(whoami)

On a headless server without a desktop session, also make sure XDG_RUNTIME_DIR is set (export XDG_RUNTIME_DIR=/run/user/$(id -u)) before retrying systemctl --user commands.

Manual user-unit example when you need a custom install path:

[Unit]
Description=OpenClaw Gateway
After=network-online.target
Wants=network-online.target
StartLimitBurst=5
StartLimitIntervalSec=60

[Service]
ExecStart=/usr/local/bin/openclaw gateway --port 18789
Restart=always
RestartSec=5
RestartPreventExitStatus=78
TimeoutStopSec=30
TimeoutStartSec=30
SuccessExitStatus=0 143
OOMPolicy=continue
KillMode=control-group

[Install]
WantedBy=default.target

openclaw gateway install
openclaw gateway status --json
openclaw gateway restart
openclaw gateway stop

Native Windows managed startup uses a Scheduled Task named OpenClaw Gateway (or OpenClaw Gateway (<profile>) for named profiles). If Scheduled Task creation is denied, OpenClaw falls back to a per-user Startup-folder launcher that points at gateway.cmd inside the state directory.

Use a system unit for multi-user/always-on hosts.

sudo systemctl daemon-reload
sudo systemctl enable --now openclaw-gateway[-<profile>].service

Use the same service body as the user unit, but install it under /etc/systemd/system/openclaw-gateway[-<profile>].service and adjust ExecStart= if your openclaw binary lives elsewhere.

Do not also let openclaw doctor --fix install a user-level gateway service for the same profile/port. Doctor refuses that automatic install when it finds a system-level OpenClaw gateway service; use OPENCLAW_SERVICE_REPAIR_POLICY=external when the system unit owns the lifecycle.

Invalid configuration errors exit with code 78. Linux systemd units use RestartPreventExitStatus=78 to stop relaunching until the config is fixed. launchd and Windows Task Scheduler do not have an equivalent per-exit-code stop rule, so the Gateway also persists rapid unclean boot history and suppresses channel/provider account auto-start after repeated startup failures. In that safe mode the control plane still starts for inspection and repair, config hot reloads and secrets.reload refuse automatic channel restarts, and an explicit operator channels.start request can override the suppression.

Dev profile quick path

openclaw --dev setup
openclaw --dev gateway --allow-unconfigured
openclaw --dev status

Defaults include isolated state/config and base gateway port 19001.

Protocol quick reference (operator view)

• First client frame must be connect.
• Gateway returns a hello-ok frame with a snapshot (presence, health, stateVersion, uptimeMs) plus policy limits (maxPayload, maxBufferedBytes, tickIntervalMs).
• hello-ok.features.methods / events are a conservative discovery list, not a generated dump of every callable helper route.
• Requests: req(method, params) → res(ok/payload|error).
• Common events include connect.challenge, agent, chat, session.message, session.operation, session.tool, opt-in session.approval, sessions.changed, presence, tick, health, heartbeat, pairing/approval lifecycle events, and shutdown.

Agent runs are two-stage:

1. Immediate accepted ack (status:"accepted")
2. Final completion response (status:"ok"|"error"), with streamed agent events in between.

See full protocol docs: Gateway Protocol.

Operational checks

Liveness

• Open WS and send connect.
• Expect hello-ok response with snapshot.

Readiness

openclaw gateway status
openclaw channels status --probe
openclaw health

Gap recovery

Events are not replayed. On sequence gaps, refresh state (health, system-presence) before continuing.

Common failure signatures

For full diagnosis ladders, use Gateway Troubleshooting.

Safety guarantees

• Gateway protocol clients fail fast when Gateway is unavailable (no implicit direct-channel fallback).
• Invalid/non-connect first frames are rejected and closed.
• Graceful shutdown emits shutdown event before socket close.
