“Eight Years with Arduino—Code Kit Pro Finally Got It Right”
“We’ve worked with Arduino Uno for the past eight years and have had difficulty finding a platform with the functionality needed.
We’ve been using Code Kit Pro for over two months now and have been extremely impressed, not only with the product but also the support we have received… So far, we have not come across anything we could not code within Code Kit Pro, and the upload to the Arduino feature has worked flawlessly.”
Robert M, Middle School Robotics Instructor

Can’t find what you’re looking for? Contact our friendly team.
Is Code Kit really free?
Yes. The web editor is free forever. Build unlimited projects, generate Arduino code, and learn at your own pace. Pro features like direct upload, cloud storage, and the desktop app are optional upgrades.
Do I need to know how to code?
No. Code Kit is built for complete beginners. Our visual blocks make programming concepts intuitive, just drag, drop, and connect.
What if I already know Arduino?
Use Code Kit to prototype faster, test sensor combinations, and teach others. The generated code is clean and customisable—perfect for starting projects quickly.
Can I use Code Kit offline?
The free web editor needs an internet connection. Pro users can download the Mac/Windows desktop app and work completely offline.
How do I transition to text-based coding?
Code Kit shows you the Arduino C++ for your blocks in real time. As you build, you’ll naturally learn control flow, functions, variables, and more.
Is there a mobile app version of Code Kit?
While we don’t have a dedicated mobile app, our web version is fully responsive and works well on tablets and smartphones. Pro users can access all features through supported mobile browsers.
Can I use my existing Arduino libraries with Code Kit?
Code Kit includes blocks for many popular libraries but doesn’t yet import custom libraries directly. You can add custom code blocks to call specialised functions, and we’re expanding library support based on user feedback.
How can I integrate Code Kit with my products?
If you’d like to bundle or recommend Code Kit with your products, please contact us before advertising compatibility. We work with partners to ensure a smooth, well‑designed experience for your users.
Supported boards
Code Kit works with a wide range of Arduino and Espressif boards—and we’re always adding more.
