High-level software platform for embedded devices

Open source programming language

Toit is built on the Toit programming language, a fast-growing open source language built for IoT. Toit language is a memory-safe, high-level coding language that executes your code in a virtual machine optimized for power consumption. Our customers run an ESP32 for years on 2 AA batteries.

Isolated software applications

The system is isolated from your code, and your applications are isolated from each other.

Built-in security

All communication is end-to-end encrypted. Finally a secure IoT platform.

Send your data to your cloud

Use HTTPS or MQTT to send your data directly from your devices to your own system, or use our built-in Pub/Sub. Deploy code, update firmware and monitor your devices. We take care of your ESP32 microcontrollers.

Deploy code with no risk

Bugs in embedded software development used to be catastrophic. With Toit, a bug in your code will only crash that one application. The system and your other applications keep running. Change and deploy new code with no risk.

Toit makes embedded development like software development. Integrate your device into your continuous delivery pipeline and deploy new code every week instead of every year.

Full serviceability for your fleet

Toit gives you a full overview of your production devices. A bug results in a stack trace that lets you fix it and redeploy in minutes.

Group your devices and update all the devices in a group in one go.

Communication to and from the device is end-to-end encrypted. Sleep well at night knowing that your devices and your data are safe.

Modern software platform

Writing code for microcontrollers is not nice. You need to code in C, and deploying a simple code update takes several minutes.

Toit is an open source programming language designed for embedded devices

Toit is a high-level object-oriented programming language built for IoT. It has full editor integration with auto completion, syntax highlighting and more.

It takes only one second to deploy code to your ESP32. It all happens over the air, and you don’t need to flash your device. No more waiting minutes like you’re used to for embedded development.
