Toit is an open-source programming language designed for Internet of Things (IoT) applications, with a focus on ESP32 microcontrollers made by Espressif Systems. It was developed by Toitware ApS, a Danish company founded in 2018, and released as open source in November 2021.
Toit was created by a team that included Lars Bak and Kasper Lund, who had previously developed the V8 JavaScript engine for Google Chrome and co-designed the Dart programming language at Google.
As of 2026, the language targets ESP32-class hardware. Using a garbage-collected runtime on a microcontroller involves memory and latency trade-offs compared to hand-optimised C, a consideration noted in coverage of the language.
Lars Bak and colleagues founded Toitware ApS in Aarhus, Denmark, in 2017–2018 to build a new programming language for IoT development. In February 2019, the company raised DKK 23 million (approximately US$3.5 million) in seed funding from Swedish venture capital firm Creandum. Early versions required cloud registration to deploy code to devices.
