Agent comparisons
Meta Muse vs OpenClaw: SOUL.md, WhatsApp, and Model Choice
Choose Meta Muse if you want a personal agent that works the minute you sign in, with Meta running the machine, the model, the credential vault, and a second agent that screens what goes out. Choose OpenClaw if you want to pick the model, edit the files that define the agent, and put it on your own WhatsApp, Telegram, or Slack. Muse was modeled on OpenClaw, so the ideas overlap. The difference is who holds the controls. Lobsterland runs OpenClaw as a managed instance, so the open option does not mean running a server.

Two names first. Muse here is the personal agent Meta launched on September 8, 2026. It is not Muse Spark, its launch model, or Muse Code, Meta's terminal coding agent. OpenClaw is the open-source agent runtime. It is not OpenClaw Launch, which is a hosting company with its own Muse comparison page.
Is Meta Muse based on OpenClaw?
In design, yes. In code, Meta says no. By September 22, users had noticed that Muse carries a SOUL.md file, the plain-text file OpenClaw uses for an agent's personality, values, and boundaries, and that its contents were nearly identical to OpenClaw's. Asked about it, Nat Friedman, head of product at Meta Superintelligence Labs, told TechCrunch on September 22, 2026 that Muse was "definitely heavily inspired as a product by OpenClaw" but "built from scratch," and that the team "thought that Peter [Steinberger, OpenClaw's creator] got those things exactly right." The Next Web reported the same exchange.
So the useful question is not whether Muse copied OpenClaw. Meta has said it did, at the level of product ideas. The useful question is what changes when the same design is run by Meta instead of by you.

The Muse column follows Meta's launch announcement and TechCrunch's launch coverage. The OpenClaw column describes what you can operate through managed OpenClaw hosting on Lobsterland.
What does SOUL.md do, and who can edit it?
In OpenClaw, SOUL.md is one file in a small set that together define the agent. SOUL.md holds voice, temperament, and the lines it should not cross. AGENTS.md is the operating contract: priorities, workflow, quality bar. USER.md holds your preferences. MEMORY.md keeps durable facts, and dated notes under memory/ hold the day-to-day. Our guide to OpenClaw's memory files walks through each one.
The reason the Muse story landed is that these are ordinary files. When the agent does something you did not want, you can open the file that shaped the behavior and change a sentence. On a managed instance the workspace is browsable and editable from the dashboard, so there is no SSH session involved. You can see what the agent has written into memory and delete what it should not keep.
Muse also exposes memory: Meta’s design account says Memory files can be read and edited directly. That is different from a documented contract for editing every runtime instruction file. OpenClaw gives you the workspace and the open-source runtime around it; choose it for that control, not because Muse memory is unreadable.
How does each one work in WhatsApp?
Both reach you in WhatsApp, and that is where the two designs differ most in practice.
Muse is a Meta agent that you message inside WhatsApp. The contact belongs to Meta, and the agent lives on Meta's side of the conversation.
OpenClaw links to a WhatsApp account you control. On Lobsterland you choose personal number mode, where you chat with the agent in your own self-chat, or dedicated number mode, where the agent has its own number and people message it. You set a DM policy (pairing, allowlist, open, or disabled) and an allowlist of numbers and groups. Then you scan a QR code from WhatsApp's Linked Devices screen. Our WhatsApp setup guide has each step. The consequence is that the policy on who may give your agent instructions is yours to set, and a stranger who finds the number gets nothing unless you allow it.
Which one does work without being asked?
Muse's pitch leans on proactivity. Meta says it remembers what matters to you, so it can make suggestions unprompted and act on details you mentioned once. That is a product behavior Meta tunes for you.
OpenClaw separates recurring schedules from the context used during a heartbeat. On the hosted v2026.10.2 image, instructions live in database-backed monitor scratch, not HEARTBEAT.md, and recurring checks require automation jobs. Lobsterland exposes a heartbeat interval with a 30-minute default, but the interval alone does not establish a running schedule. Empty scratch or busy queues can skip work. Check the version-sensitive heartbeat documentation and verify both run history and delivery to your intended chat. The OpenClaw cron guide explains the broader scheduling model.
Running proactive agents for customers taught us that the hard part is not the timer. It is where the message ends up. A heartbeat that lands in the middle of your Telegram thread becomes the "previous message" in your next conversation, so managed instances run heartbeat turns in an isolated session. Since September 25, 2026, we also route a heartbeat's delivery to the channel and thread you last used, instead of OpenClaw's default owner direct message. With that default, the result of a long-running task started in a Telegram group could arrive in the owner's private chat instead of the group. Muse handles this kind of routing for you. With OpenClaw, it is a setting, and on Lobsterland the defaults are already chosen.
Where is Muse ahead of OpenClaw?
Trust machinery for money and email. Muse runs a second agent, the Sentinel, on the same VM, and Meta says nothing Muse does reaches the internet unless the Sentinel approves it. Passwords and cards go into storage Muse can use but not see, and checkout goes through Stripe Link with a one-time card and Link's purchase protections. Muse asks before sending email or buying anything. OpenClaw has no built-in equivalent to a Sentinel. On an OpenClaw instance your controls are narrower grants, allowlists, and reviewing what the agent is allowed to do. Our security overview spells out where the managed boundary stops.
Integrated services. Meta’s September 29 business announcement adds connectors including Slack, Shopify and QuickBooks. OpenClaw reaches services through the tools, skills and optional hosted browser you configure; a model key does not grant those app permissions.
No runtime to provision. Muse offers a free usage allowance and integrated onboarding. Its Mac app can work with computer files and apps with permission. Do not confuse our cloud Hosted Browser with control of your own Mac. Review the access you grant either product before giving it real work.
Model choice also changes over time. Meta’s October 12, 2026 announcement says Muse Wonder will reach Muse subscribers first. It does not confirm access for every account. OpenClaw’s choice is a supported model provider you configure.
Is OpenClaw cheaper than Muse?
Muse’s free allowance can be cheaper for light personal use. Its product page confirms usage limits and paid subscriptions; check the offer in your account for current dollars and allowances. The September launch announcement describes US availability, so verify country eligibility at signup.
As of October 14, 2026, managed OpenClaw starts at $6.90 per month, with model use and optional add-ons separate. ChatGPT/Codex login uses a supported ChatGPT plan. For Claude, use an Anthropic API key; a connected Claude login does not promise that Pro or Max covers hosted usage. Anthropic restricts third-party use of subscription credentials. The hosting trial lasts seven days and requires a card up front. Compare your expected model bill and hosting tier on the pricing page.
How do you try OpenClaw without a server?
- Create a Lobsterland account and choose OpenClaw for a new instance.
- Connect a model provider or ChatGPT/Codex login. Use an Anthropic API key for Claude.
- Open the workspace and write three lines into
SOUL.mdandUSER.md: who the agent is, what it must never do, and how you like answers. - Test in built-in chat, then link WhatsApp, Telegram, or Slack. Add a scheduled automation once one task works reliably, then verify its run history and destination.
A fair first test is something Muse would also do: summarize the week's plans from a message you forward, and list what is still undecided. If it misses something, change the instruction file and try again. That gives you a direct way to test changes to OpenClaw’s operating instructions.

Frequently asked questions
Is Meta Muse based on OpenClaw?
Meta says Muse was built from scratch but was heavily inspired by OpenClaw. Users found that Muse carries a SOUL.md file nearly identical to OpenClaw's, and Meta's Nat Friedman said the team thought OpenClaw's creator got those things exactly right. Muse does not run the OpenClaw runtime.
Can I edit Muse's SOUL.md the way I can in OpenClaw?
Meta documents directly editable Memory files. That does not establish the same supported SOUL.md editing contract as OpenClaw. In OpenClaw, SOUL.md, AGENTS.md, USER.md, MEMORY.md and the other workspace files are plain files you can open and change; on Lobsterland they are editable from the dashboard.
Do Muse and OpenClaw both work in WhatsApp?
Yes, differently. Muse is a Meta agent you message inside WhatsApp. OpenClaw links to a WhatsApp account you control, personal or dedicated number, through WhatsApp's Linked Devices QR flow, with a DM policy and allowlist deciding who can reach it.
Is OpenClaw cheaper than Muse?
Not for light use: Muse has a free tier. Paid Muse subscriptions are available; check your account for current prices and limits. Managed OpenClaw on Lobsterland starts at $6.90 per month plus your model provider's bill, so heavy use depends on your model spend.
