Enhanced sextech innovation for better intimacy and pleasure, featuring cutting-edge sex toys and gadgets, designed for increased satisfaction and sexual wellness.

Buttplug.io

Buttplug.io is an open-source software project that does the behind-the-scenes heavy lifting for a huge chunk of the sextech world. It’s basically a universal remote control protocol for sex toys—instead of every app or game needing to separately figure out how to talk to hundreds of different Bluetooth vibrators, strokers, and fuck machines, developers can just integrate Buttplug and instantly get compatibility with a massive library of devices. Think of it as the USB standard, but for intimate hardware. The project started around 2017 because the founder got fed up with the proliferation of manufacturer-specific apps that locked toys into their own ecosystems. By reverse-engineering device protocols (mostly Bluetooth LE), Buttplug became the go-to solution for developers who wanted to add sex toy control without reimplementing low-level hardware communication. It’s open source under a permissive BSD 3-Clause license and provides libraries in multiple languages (Rust, C#, JavaScript) with cross-platform support for desktop, mobile, and web. The project also includes Intiface, which are the user-facing apps and engines that actually connect and control devices using the Buttplug protocol. Buttplug powers a surprising range of applications—from retro shooter Ultrakill getting official sex toy support to Animal Crossing integrations. It’s also become infrastructure for the DIY sextech community, as we covered in our guide to getting started in sextech hacking. The project maintains an IoT compatibility index (IOSTIndex) and has been adopted by third-party developers and even some manufacturers. Beyond just technical specs, Buttplug documents an ethical stance emphasizing user safety, autonomy, and human rights in sex technology—a refreshing position for foundational infrastructure in an industry that doesn’t always prioritize those values.
