10 Surprising Facts About the Ploopy Bean: The Open-Source Pointing Stick Mouse

When you think of computer mice, the first image that comes to mind is probably a plastic blob with two buttons and a scroll wheel. But the reality is far more diverse—and for anyone craving a truly unique input experience, the Ploopy Bean is a breath of fresh air. This small Canadian company has created a pointing stick mouse with four buttons and fully open-source QMK firmware. In this listicle, we break down the ten most compelling aspects of this quirky device, from its ergonomic design to its hacker-friendly soul.

1. What Exactly Is the Ploopy Bean?

The Ploopy Bean is a compact input device that uses a pointing stick (similar to the TrackPoint on old ThinkPads) instead of a traditional ball or laser. It’s essentially a stationary mouse: you keep your hand in one place and nudge the nub to move the cursor. The Bean is about the size of a deck of cards, making it highly portable. It’s a wired USB-C device that connects to any computer—Windows, macOS, or Linux—without additional drivers. The name is intentionally silly, reflecting the company’s playful attitude toward a niche product.

2. Four Buttons: More Than Meets the Eye

At first glance, the Bean appears to have just two buttons (left and right click). But hidden on the sides are two more buttons that function as middle click and back/forward navigation. This layout lets you keep your thumb and index finger in constant contact with the pointing stick, reducing hand movement. The fourth button can be remapped via QMK firmware to any keyboard shortcut you like. Whether you need a quick “Ctrl+W” to close tabs or a media play/pause toggle, the extra buttons eliminate the need to reach for the keyboard.

3. Open-Source QMK Firmware: Total Control

Unlike most mice where firmware is locked and proprietary, the Ploopy Bean runs QMK (Quantum Mechanical Keyboard) firmware entirely open source. This means you can modify every aspect of its behavior: pointer speed, button actions, acceleration curves, even lighting if you add an LED. The firmware is stored on the device itself, so your customizations travel with you. This is a godsend for Linux users who hate dealing with buggy OEM drivers. You can flash new firmware using a simple web tool or compile it yourself from the GitHub repo.

4. Pointing Stick vs. Trackball vs. Traditional Mouse

The Bean’s pointing stick offers a unique middle ground. Unlike a trackball, which requires your thumb to roll a ball, the pointing stick uses a pressure-sensitive nub. You don’t move the nub—you push it, and the cursor accelerates proportionally. This means zero desk space is needed; you can use the Bean on your lap, on a book, or even on your leg. Compared to a traditional mouse, the Bean reduces wrist fatigue because your arm stays stationary. The tradeoff is a learning curve: cursor control takes a few days to master, but many users say it feels more precise once you do.

5. Made by a Canadian Company with a Mission

Ploopy is a small operation based in Toronto, Canada. They’re not mass-producing in China; each Bean is hand-assembled in their workshop. The company’s mission is to democratize input devices—hence the open-source hardware design. You can even buy the Bean as a DIY kit and solder it yourself. This transparency means if a component fails, you can replace it without throwing away the whole unit. The team actively participates in online forums, quickly fixing bugs and accepting community pull requests.

6. Who Is the Ploopy Bean For?

This device isn’t for casual gamers or people who just browse Facebook. It’s aimed at power users, programmers, and ergonomic enthusiasts. Specifically, the Bean shines in environments where desk space is limited (coffee shops, airplane tray tables) or where repetitive strain injury (RSI) is a concern. Many users with wrist pain find the pointing stick more comfortable than a mouse. It’s also popular among mechanical keyboard hobbyists who want a matching input device that’s just as moddable.

7. Build Quality: Sturdy and Serviceable

The Bean’s shell is made of thick, matte-finish plastic with a metal plate inside for weight and durability. The pointing stick is a genuine ALPS sensor (the same used in ThinkPads), known for longevity. The buttons have a tactile, responsive click with low actuation force. The only potential weak point is the USB-C port, but the board uses a reinforced connector. Because the design is open source, you can 3D-print replacement parts if the case cracks. The entire device can be disassembled with a standard Phillips screwdriver.

8. Compatibility and Setup: Plug-and-Play with a Twist

Out of the box, the Ploopy Bean works natively on Windows, macOS, and most Linux distros as a standard pointing stick with basic two‑button support. To unlock the full four‑button and QMK customisation, you need to flash the firmware. Ploopy provides a web-based configurator at config.ploopy.co that works in any browser. No software installation is required. For advanced users, the GitHub repo includes source code and compilation guides. The device also emulates a keyboard, so any remapped button can send any keycode your OS understands.

9. Community and Modifications

The Ploopy Bean has a thriving community on Reddit (r/ploopy) and Discord. Enthusiasts share custom firmware profiles, 3D‑printed cases, and even trackball hybrids. Because the PCB is open source, you can add your own features: extra LEDs, haptic feedback, or a scroll wheel. Some users have converted the Bean into a one-handed keyboard by remapping buttons to layer keys. The community is extremely welcoming to beginners—if you get stuck, someone will walk you through the flashing process in real time.

10. Price, Availability, and Alternatives

The Ploopy Bean costs $69 USD for the assembled version or $59 USD for the DIY kit. Shipping is free within Canada and the US. It’s sold exclusively through the Ploopy website, with occasional drops on Etsy. Compared to other pointing stick devices (like the ThinkPad TrackPoint Keyboard II or the much more expensive TextBlade), the Bean is a bargain—especially considering its customisability. Alternatives include the Ploopy Trackball (also open source) or a used ThinkPad keyboard with a TrackPoint, but neither offers the compact standalone form factor of the Bean.

Conclusion

The Ploopy Bean is far more than a gimmick; it’s a thoughtfully engineered tool for anyone who spends long hours at a computer. Its combination of open-source firmware, four intuitive buttons, and a compact pointing‑stick interface makes it a standout in the niche world of alternative input devices. Whether you’re battling RSI, maximizing desk space, or simply love tinkering with hardware, the Bean delivers a level of control and community support that mainstream mice can't match. If you’re ready to rethink how you interact with your computer, the Ploopy Bean might just be the quirky upgrade you never knew you needed.
