Resident: vibe coding firmware (our new sandbox library for ESP32 devices) 14.14, Wednesday 20 May 2026 Link to this post We’re open sourcing Resident, our library for running AI-authored code on microcontrollers – with no compile step and no firmware flashing. It’s our twist on vibe coding firmware, built for instantly loading new device functionality coded by end users. It’s aimed at device developers, like us. We use Resident in all our work. (We = Inanimate.) Resident gives you a code sandbox on ESP32 devices and a driver API to provide hardware control and events. So an end user can push an app over Wi-Fi that instantly turns their clock into an interactive pill timer (for example) but the app can’t run probes on the home Wi-Fi network. It comes bundled with a set of Claude skills.
