OpenMuse is made by CopilotKit, not Meta. CopilotKit does not describe it as a Muse alternative; we compare the two because both are personal agents with their own browser that keep working after you close the app.

In short

CopilotKit’s alpha template for a personal agent: ask for an outcome, follow the plan, approve the actions that matter, and come back to the result. It has one interface for iPhone, Android and the web that you build and host yourself.

Made by: CopilotKit · Where your data lives: On the server you run (API, task worker and browser worker), plus your CopilotKit Intelligence project.

The editor’s take

For developers who like the idea of Muse but want the code and the data under their own control. It is a template, not a ready-made app.

Best for

Developers who like to tinker

People comfortable with Node.js who want a personal agent they can inspect and extend.

Check first

Not a Muse copy

CopilotKit does not call it a Muse alternative; it is alpha and needs a CopilotKit Intelligence key.

Download & install

Every link goes to the official site, an official app store, or the project’s own GitHub releases.

Getting started without coding

Plain-language steps based on the official install guide.

Difficulty: Advanced

You need to run a server (Docker or command line), or ask someone who can.

No installer, app-store listing or hosted version: you run it from a terminal with Node.js and pnpm, and building the phone apps needs Xcode or Android tools.

Is there an installer?

  • Windows Not available
  • Mac Not available
  • Linux Not available
  • iPhone & iPad Not available
  • Android Not available
Hosted version

No official hosted version. There is no hosted version. The README offers a “Deploy to Render” button, which runs it on your own Render account.

Steps for Your own server

  1. Install Node.js 24 and pnpm 11, and create a CopilotKit Intelligence project key.
  2. Clone the repository, run “pnpm install”, copy .env.example to .env and add the project key.
  3. Run “pnpm dev”, then “pnpm dev:web” in a second terminal, and open http://localhost:8081.

Try before you move

A simple way to see if it fits your needs.

  1. Start with a low-risk taskGive it a job where a mistake costs little, such as summarising a public page.
  2. Check what it can reachReview which accounts it connects to and which actions need your approval.
  3. Count the running costsModel API usage, hosting and data retention all add up over a month.
