Interactive coding
Visually construct programs with an intuitive, block-based interface. Arduino code generates instantly as users add and rearrange blocks.
Direct code upload
Visually construct programs with an intuitive, block-based interface. Arduino code generates instantly as users add and rearrange blocks.
Perfect for classrooms
Visually construct programs with an intuitive, block-based interface. Arduino code generates instantly as users add and rearrange blocks.
Typed Variables
Code Kit includes all fundamental Arduino variable types. Users can explore integer, float, boolean, character, and string types through a variety of blocks and block connections.
Regular updates
Code Kit is continually evolving. We’re committed to improving the app with new features and improvements in aid of our mission to make coding accessible for all.
Mobile compatible
Our web app works on mobile browsers on both iOS and Android so you can take your coding with you, wherever you go.
One-click copy or download
Copy generated code to your clipboard in just a click, or download a zipped .ino project.
Hardware-centric design
Unlike other block based coding apps, Code Kit focuses exclusively on hardware. By enabling interactive physical experiences, we create opportunities for rich educational opportunities and positive first experiences with code.
We support a wide range of Arduino and Arduino-compatible boards. Launch Code Kit on the web to view the full range of compatible boards.
Customisable blocks toolbox
Enable the categories you want. Hide the ones you don’t. Perfect for simplifying the interface for beginners.
We thought of the little things
The little things like loading animations and customisable themes. Code Kit is fun to use.
Built-in serial monitor
Engage with live data streams from your connected devices, granting you instant feedback for real-time tweaking and diagnostics.
Choose to dive into the raw output for detailed data analysis, or embrace clarity with our multi-variable graphing option, transforming complex readings into understandable, interactive visualisations.
Cloud project storage
Save your Code Kit projects directly to the cloud, ensuring they’re secure and readily accessible for whenever inspiration strikes, from any device, anywhere, through Code Kit Web.
Effortlessly share your projects with a public URL that can be distributed to anyone, even if they don’t have Code Kit Pro.
Frequently Asked Questions

Got a question? We’ve got you covered! Check out the resources below and be sure to let us know if we can answer anything else.
Is Code Kit free to use?
Yes! Our basic web edition of Code Kit has always been free for personal and educational use.
Because we offer this for free, we politely ask that you don’t copy our app to other sites or sell copies of our app to other people/organisations.
What makes Code Kit the best visual coding editor for Arduino?
We’ve spent a lot of time and effort making Code Kit the very best it can be. Our primary focus has always been user experience, so we strive to maintain a service that is easy-to-use and simple yet powerful.
If you’ve used other visual coding editors for Arduino, you’ll know that Code Kit is very different. Here are some of the things we believe make it the best:
- Intuitive interface — Blocks are well-organised, colour-coded, and easy to use. Users can customise the interface to suit their preferences. The toolbar makes it simple to open, save, and upload code, among other things.
- Variables — Code Kit uses typed variables (i.e. int, float, bool, string) and almost every block can take variables as inputs. Users can control inputs, outputs, and more with variable pin assignments and variable values.
- Block selection — We’ll admit that Code Kit doesn’t have the largest block library. If you’re looking for an RFID reader block, or a block for an OLED screen, another solution may suit you better. However, we have chosen and designed our blocks very intentionally. Unlike other editors, we cover a large portion of the Arduino language specification which makes it easy for users to transition to text-based coding—the main goal of any visual coding editor.
This list is not extensive. We invite you to try Code Kit for yourself and see if you agree!
What’s the difference between Code Kit Free and Pro?
Code Kit Free is our free version of Code Kit, available on all devices through the web. There are countless blocks to choose from, an intuitive user-interface, and guided tutorial videos that make it simple to get started.
Code Kit Pro has everything that’s great about its free counterpart, and unlocks a host of additional functionality. With Code Kit Pro, upload code directly to connected boards, access live serial monitor output with advanced graphic features, and store and share your projects on the cloud. Our Pro edition is a paid upgrade that supports the continued development of Code Kit.
