Meta has published open-source code that lets developers build their own hardware around Muse, the company's new AI agent. The SDK, released on GitHub under Meta's facebookincubator organization, targets off-the-shelf maker boards rather than custom silicon — a deliberate choice that puts the company's agent software on hardware Meta does not manufacture or sell.

The release includes SDKs for two platforms: Espressif's ESP32 microcontroller family and the Raspberry Pi single-board computer. "Muse gadgets are open source devices you build yourself," Meta says. "Program an off-the-shelf ESP32 board or set up a Raspberry Pi with our SDKs, then connect Muse to your displays, buttons, sensors, actuators, and whatever else you've got lying on your workbench."

Meta suggests three reference projects in its documentation. Builders can load Muse onto a color E Ink display to surface reminders, run the agent on an HDMI stick to put Muse on a large screen, or mount it on a small touchscreen device — a configuration Meta likens to a homemade version of the Muse Charm, the company's own AI hardware product.

The choice of ESP32 is notable for the component side of the story. Espressif's ESP32 line combines a Wi-Fi/Bluetooth system-on-chip with modest CPU power at a unit cost of a few dollars, and it has become the default silicon for hobbyist and low-volume IoT products. By writing a first-class SDK for that ecosystem, Meta positions Muse to run on hardware that already ships in enormous volumes through distribution channels the company does not control — a contrast with the captive-device strategy behind products like the Muse Charm.

Raspberry Pi support extends the same logic to makers who want more compute headroom, pairing the agent with standard displays, sensors and actuators over common interfaces rather than a locked-down reference design.

For Meta, the open-source release serves a straightforward commercial purpose: it seeds an ecosystem of Muse-adjacent devices without the company carrying inventory, certification, or manufacturing costs. Every DIY gadget built from the SDK extends the reach of Meta's agent software into homes and workbenches at near-zero marginal cost to the company.

The move also gives developers and hardware hackers an early look at how Meta expects Muse to interact with physical peripherals — displays, buttons, sensors and actuators — ahead of a broader family of Muse hardware.

With the SDK now public on GitHub, the practical question is adoption: whether the maker community produces designs durable enough to graduate from workbench projects to products, and how Meta's first-party Muse Charm competes with gadgets its own software enables.
