Reachy Mini Alternatives: 4 Robots Worth Comparing

The Four Robots Buyers Compare Against Reachy Mini

The real alternatives to Reachy Mini are Microduck, Open Duck Mini, StackChan, and Doly. Every guide we write on this site starts from the job a robot is built to do. Each one wins on a different question than price. Price comes second. These four barely resemble each other once you get past the price tag.

Reachy Mini itself is a stationary desktop robot from Pollen Robotics, sold through Hugging Face. It is built for interaction. It does not move. It ships as a kit. The Lite version costs $399 and tethers to a computer over USB. The Wireless version costs $499 and adds its own Raspberry Pi Compute Module 4 and a battery. Both versions carry the same 120 degree camera and four microphone array. Both install apps in one click from Hugging Face Spaces. Hugging Face reported nearly 10,000 Reachy Mini units in the wild as of May 2026, with over 200 community apps built by more than 150 creators.

Two other Hugging Face products sit near Reachy Mini. Neither belongs on this list. SO-101 answers a manipulation question, taught by demonstration through LeRobot. Reachy 2 is a full research humanoid, priced for labs rather than desks. Neither one competes for the buyer this page is written for.

Four decisions separate the real alternatives from each other.

• Stay with the same maker and train a robot that walks.
• Build your own robot and own every design file.
• Spend a fraction of the price.
• Add mobility Reachy Mini does not have.

Microduck: The Same Maker's Walking Robot

Microduck is the one alternative that comes from Pollen Robotics itself. It is sold through Hugging Face, and it solves the one problem Reachy Mini cannot touch: locomotion. It costs $399, the same as the Reachy Mini Lite. It stands 25 cm tall and carries 15 motors, a camera, a lidar, and two motion sensors split between body and head.

You train it yourself, with reinforcement learning run in a MuJoCo-based simulator. Pollen Robotics ships it with seven moves already trained, including walking, sitting, and kicking. That training step is real work. Reachy Mini never asks it of you, because Reachy Mini has no legs to train in the first place.

Choose Microduck over Reachy Mini when the project is about balance, gait, or recovery rather than conversation or gesture. Our Microduck review and our Microduck versus Reachy Mini comparison cover the full spec picture if walking is the point.

Open Duck Mini: The Fully Open Build-It-Yourself Route

Open Duck Mini v2 is a fully open bipedal project built by Antoine Pirrone. It is published on GitHub with a bill of materials targeted under $400. Every mechanical file is public, designed on Onshape. A cracked leg means printing a new one instead of filing a warranty claim.

It trains the same way Microduck does, with reinforcement learning in MuJoCo. It credits Hugging Face and Pollen Robotics as sponsors of the project. What arrives is a parts list, CAD files, and build guides. There is no working robot inside the box. A first multi-servo build regularly costs more weekends than the training itself.

Choose Open Duck Mini over Reachy Mini when owning every design file matters more than an app store that already exists. Our Microduck versus Open Duck Mini comparison works through the buy-or-build tradeoff on the walking side of this decision in full.

StackChan: The $99 Entry Point

StackChan is an open-source desktop robot from M5Stack, a maker built around its own modular ESP32 boards. It undercuts the Reachy Mini Lite by $300. It runs on M5Stack's CoreS3 board with an ESP32-S3 chip. A 2 inch touchscreen shows an animated face and pans and tilts on two servo motors, one turning 360 degrees and one tilting 90.

Setup needs no soldering. The published path connects StackChan to a large language model, so it holds a conversation much like Reachy Mini's own conversation app does. The difference is a screen face instead of a moving head and antennas. Both the hardware and the firmware are open, with design files published on GitHub.

Choose StackChan over Reachy Mini when $99 is the real ceiling and a screen-based face is an acceptable trade for six degrees of freedom in a moving head. Check the current price on M5Stack's own store before ordering. Hardware from a smaller maker moves between batches.

Doly: The Mobile Companion with Tracks

Doly comes from Limitbit Inc. It solves the one thing every desk robot on this page cannot: moving around a room on its own. It rides on two continuous tracks and carries an 8 megapixel wide-angle camera, two microphones, a six-axis motion sensor, and four infrared edge sensors. It returns to a dock to charge itself.

A Raspberry Pi Compute Module 4 runs the whole thing, the same processor family the Reachy Mini Wireless uses for its own onboard compute. Limitbit publishes CAD files plus a Python and C++ software development kit (SDK) for anyone who wants to extend it. Doly currently lists at $566 Canadian dollars, on sale from $637. Limitbit states that price is temporarily raised by supply constraints on the higher-memory model.

Choose Doly over Reachy Mini when the household use needs a robot that can follow you into the next room. Reachy Mini only ever watches you from a fixed spot on a desk. At today's price Doly costs more than either Reachy Mini version, and it gives up the moving head and the app store in exchange for that mobility.

Who Should Not Switch Away from Reachy Mini

Buyers who already own Reachy Mini and use its app store have no reason to switch to any robot on this page. The apps, the one-click install from Hugging Face Spaces, and close to a year of community answers do not transfer to different hardware. Starting over loses all of that.

Skip every alternative here if the plan depends on the moving head and antenna gestures Reachy Mini was built around. Microduck cannot make that expression at all. StackChan's screen face is a different kind of expressive, and Doly's round-eye displays are simpler still.

Skip Open Duck Mini and StackChan specifically if soldering, 3D printing, or firmware setup is not work you want to do. Open Duck Mini needs a 3D printer. StackChan needs basic firmware flashing. Doly ships ready to run, with none of that.

Buyers who want a finished companion robot, with nothing to build or train, should look past this whole list. Our Microduck alternatives roundup covers Eilik and Loona, two companion robots with fixed behavior and no assembly at all.

Reachy Mini Alternatives: The Verdict

Pick Microduck when the project is locomotion and you want to stay inside the Pollen Robotics ecosystem you already know. It costs the same $399 as the Reachy Mini Lite, so the decision comes down to the job. Price does not decide it here.

Pick Open Duck Mini when owning every file matters more than a working app store on day one. It is the only alternative here with fully open mechanical designs. That keeps mattering years later, once something breaks.

Pick StackChan when $99 is the real budget. A touchscreen face is an acceptable substitute for a moving head with six degrees of freedom, once you accept the trade.

Pick Doly when the robot needs to leave the desk and follow you around a room. Nothing else on this page, including Reachy Mini itself, can do that. Confirm its current Canadian-dollar price before ordering, since Limitbit describes that figure as temporarily inflated.

What would change this verdict is Reachy Mini shipping a mobile base of its own. Hugging Face has not announced one. Until it does, mobility is the one axis where these alternatives win outright.
