Self-hosted assistant, verified from its own docs

OpenClaw and iMessage: what it is, what it needs, what it is not
OpenClaw is a free, self-hosted AI assistant that connects chat platforms, including iMessage, to AI agents running on your own machine. Its iMessage channel runs through a local tool called imsg on a Mac that stays signed in to Messages with Full Disk Access and Automation permissions granted. It is a personal or small-team developer tool, not a hosted business iMessage API like Beam.
This page describes OpenClaw using only facts published in its own documentation. Beam has no affiliation with OpenClaw.
What OpenClaw is
OpenClaw describes itself as an assistant that organizes inboxes, sends emails, manages calendars, and completes tasks, reachable through chat apps such as WhatsApp, Telegram, Discord, Slack and iMessage. According to its own homepage, OpenClaw is stewarded by the OpenClaw Foundation, described as an independent nonprofit that employs the core team and signs every release, and the project is released under the MIT license with no subscription, hosted tier or paid edition.
OpenClaw's creator is reported to also work at OpenAI, but OpenClaw states plainly that it is not an OpenAI product. It is free to download and run on hardware you control, which is a different model from a hosted business platform that runs the sending infrastructure for you.
How OpenClaw's iMessage channel works
Per OpenClaw's iMessage channel documentation, the integration runs through imsg, a native command-line tool that the OpenClaw Gateway spawns as a subprocess, communicating over JSON-RPC on standard input and output rather than a network port. The Gateway and imsg must run on, in the docs' own words, "the same signed-in macOS Messages host."
If the Gateway itself runs somewhere else, the docs describe pointing its iMessage CLI path at a transparent SSH wrapper that executes imsg on the Mac. Either way, a real Mac with an active Apple ID signed in to Messages sits behind every OpenClaw iMessage conversation.
What an OpenClaw iMessage setup requires
Based on the documented requirements, running OpenClaw's iMessage channel means providing:
- A Mac that stays on and signed in to the Apple ID that will send and receive the messages.
- The Messages app active on that Mac, with
imsginstalled through Homebrew during OpenClaw's setup flow. - macOS Full Disk Access and Automation permissions granted to
imsg, since it reads the Messages data store and drives the Messages app. - System Integrity Protection (SIP) disabled if you want the documented "private API" features: threaded replies, tapbacks, message effects, polls and group management. The docs note these stay unavailable while SIP remains enabled.
OpenClaw's docs also describe an inbound-recovery behavior worth knowing about either way you connect iMessage: after a bridge or Gateway restart, iMessage replays messages that were missed while it was down, with deduplication handled automatically.
OpenClaw iMessage setup overview
At a high level, OpenClaw's own quickstart describes: installing OpenClaw and the imsg plugin, granting the macOS permissions above, configuring the iMessage channel in OpenClaw's local JSON configuration, starting the Gateway with openclaw gateway, and approving the first direct-message pairing under OpenClaw's default pairing policy. Follow OpenClaw's current iMessage setup guide directly for exact commands and version-specific steps, since a self-hosted project's setup flow can change between releases.
OpenClaw vs a hosted business iMessage API
OpenClaw and Beam solve different problems. OpenClaw gives one person or a small team a self-hosted assistant across several chat apps, including iMessage, for free. Beam is a hosted business messaging platform built around a dedicated business line, a shared team inbox, CRM workflows and an MCP server and API for connecting an AI agent, without you running or maintaining a Mac.
| Factor | OpenClaw (self-hosted) | Beam (hosted business API) |
|---|---|---|
| Where it runs | Your own Mac, kept on and signed in to Messages | Beam's hosted infrastructure; you connect over API, MCP or a CRM webhook |
| Messaging identity | Your personal or team Apple ID | A dedicated business line, separate from a personal Apple ID |
| Who keeps it running | You: Mac uptime, macOS permissions, updates | Beam's platform operations |
| CRM workflow | Not documented as a built-in feature | Documented GoHighLevel Custom Webhook workflow |
| Other channels | WhatsApp, Telegram, Discord, Slack and more, per channel plugin | iMessage, Android RCS where supported, and SMS fallback from one line |
| Cost model | Free, MIT licensed, no hosted tier | Paid plans; Not stated publicly on this page, see Beam's own pricing when you sign up |

Who each option actually fits
OpenClaw's iMessage channel fits someone comfortable running and maintaining a Mac, who wants one assistant across several personal chat apps and is fine with a single Apple ID doing the sending. It is not described anywhere in its own docs as a business-grade, multi-client platform.
A hosted option like Beam fits a business or agency that wants a dedicated line separate from anyone's personal Apple ID, a shared inbox several teammates can answer from, and a documented way to plug in a CRM workflow or an AI agent over MCP without hosting a Mac themselves.
Before you connect
Questions before you choose a setup
What is OpenClaw?
OpenClaw is a free, self-hosted AI assistant, released under the MIT license by the OpenClaw Foundation, that connects chat apps including WhatsApp, Telegram, Discord, Slack and iMessage to AI agents running on hardware you control.
Does OpenClaw support iMessage?
Yes. OpenClaw documents a native iMessage channel built on a command-line tool called imsg, which talks to the Messages app on a Mac over JSON-RPC rather than a separate server or port.
What do I need to run OpenClaw's iMessage channel?
A Mac that stays on and signed in to the Apple ID you want to use, with Messages active, imsg installed, and macOS Full Disk Access and Automation permissions granted. Advanced features like tapbacks and group management also require System Integrity Protection to be disabled.
Is OpenClaw free to use?
Yes. OpenClaw's own homepage states there is no subscription, hosted tier or paid edition, and the full project is released under the MIT license.
Can OpenClaw replace a business iMessage API?
OpenClaw's documentation describes a self-hosted assistant for one Apple ID, not a business platform. A hosted option like Beam adds a dedicated business line, a shared team inbox and a documented CRM and MCP integration that OpenClaw's docs do not describe.
Is OpenClaw affiliated with Apple, Anthropic or Beam?
No. OpenClaw is an independent project stewarded by the OpenClaw Foundation. It has no connection to Beam, and this page is not affiliated with OpenClaw, Apple or Anthropic.
What is the alternative if I do not want to run a Mac myself?
Connect an AI agent to iMessage through a hosted platform instead. Beam documents an API, webhooks and an MCP server for Claude Code, Claude Desktop and other compatible clients, so the business line and uptime are Beam's responsibility, not yours.

Want the hosted version instead?
Tell our team about your setup. We will walk through connecting iMessage, RCS and SMS to your business without you running a Mac.
iMessage and RCS avoid the carrier A2P 10DLC registration process. SMS fallback remains subject to applicable carrier A2P requirements.
