SlimeVR Butterfly Trackers: Thinner, Lighter Full-Body VR Partners You’ll Love (2026)

Revolutionize Your VR Experience with SlimeVR's Butterfly Trackers: A Thinner, Lighter, and More Powerful Upgrade

SlimeVR is back with a groundbreaking crowdfunding campaign, introducing the next-generation Butterfly Trackers that are set to transform the VR world. These sleek and lightweight devices promise an unparalleled VR experience, offering a longer-lasting battery and enhanced tracking capabilities.

The campaign launched on February 9th and quickly surpassed its funding goal of $180,000, currently sitting at an impressive $347,000 from nearly 760 backers. This isn't SlimeVR's first successful crowdfunding venture; their original Full-Body Tracker raised over $9 million in 2021, proving their expertise in VR technology.

The Butterfly Trackers utilize the same IMU-based body tracking solution as the original Full-Body Tracker, ensuring seamless avatar articulation without the need for base stations or external sensors. This technology is also invaluable for motion capture and VTubing.

However, the real innovation lies in the custom 2.4 GHz dongle, replacing Wi-Fi. This design choice enables the trackers to be remarkably thin, light, and long-lasting, with an estimated battery life of up to 48 hours on a single charge—a significant improvement over the original Full-Body Trackers.

The thinness and lightness of the Butterfly Trackers also introduce new attachment methods, including straps, clips, and even iron-on patches, providing users with flexibility and convenience.

SlimeVR's trackers are compatible with a wide range of standalone headsets, including Meta Quest, Pico, and Steam Frame, as well as any headset that uses SteamVR. This compatibility ensures a broad appeal and versatility for various VR enthusiasts.

The campaign offers the 'Core Set Bundle' at $279, containing six Butterfly Trackers. This bundle is sufficient for tracking the position and rotation of the hip, knees, and chest, as well as the position of the feet. Backers can expect their rewards by August 31, 2026.
