Code Kit Pro

Direct code upload

Build your program visually with intuitive blocks. Code Kit generates clean Arduino C++ as you go.

With Code Kit Pro, you can upload code directly to connected boards in a single click. No extra windows, no manual copying.

• Available in the web app (no install required)
• Included with desktop apps for Windows, MacOS, and Linux

Experimental Feature

Text-to blocks with BlockMorph

BlockMorph turns text‑based Arduino C++ into interactive, editable blocks.

• Paste in existing code and see it become blocks you can rearrange
• Edit either the blocks or the text and watch the other update
• Use it to learn, refactor old sketches, or explain code visually to others

BlockMorph lets you see how code works, so you can understand it faster and create with more confidence.

Built-in serial monitor

See what your project is doing in real time.

• View raw serial output for detailed debugging
• Plot multiple sensor values at once with our graph view
• Tune and troubleshoot your hardware without leaving Code Kit

Desktop apps with offline support

Code Kit Pro comes with desktop apps for Windows, MacOS, and Linux.

• Compile and upload code completely offline
• Upload directly to connected boards
• Use the serial monitor with raw and graph views
• Access all core Pro functionality without a browser

Cloud project storage

Save your projects securely to the cloud and pick up where you left off from any device using Code Kit Web.

• Access your work anywhere
• Keep backups of important projects
• Share a public URL so anyone can view (and remix) your creations—even without Code Kit Pro
