Can’t find what you’re looking for? Please contact our friendly team.
Is Code Kit really free?
Yes! Our web editor is completely free forever. You can build unlimited projects, generate code, and learn Arduino programming without paying anything. Pro features like direct upload and cloud storage are optional upgrades.
Do I need to know how to code?
Not at all! Code Kit is designed for complete beginners. The visual blocks make programming concepts intuitive—just drag, drop, and connect. Focus on building your ideas, not learning syntax.
What if I already know Arduino?
Code Kit accelerates your workflow. Use it for rapid prototyping, testing sensor combinations, or teaching others. The generated code is clean and customizable—perfect for starting projects quickly.
Can I use Code Kit offline?
The free web version needs internet. Pro users can download our desktop app for Windows and Mac that works completely offline. Your projects sync when you reconnect.
How do I transition to text-based coding?
Code Kit shows you the Arduino code for every block in real-time. You’ll naturally learn control flow, functions, and programming concepts as you build.
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?
While Code Kit includes blocks for many popular libraries, you can’t directly import custom libraries. However, users can add custom code blocks, allowing integration of specialised functions. We’re constantly expanding our library support based on user feedback.
How can I integrate Code Kit with my products?
If you are a company looking to use Code Kit with your products, we ask that you contact us to discuss possible solutions and/or collaborations. Please don’t advertise compatibility with Code Kit before reaching out—it is our goal to ensure each user’s experience is positive and well-designed.
Supported boards
Code Kit works with a wide range of Arduino and Espressif boards—and we’re always adding more.
