Blockly and Raspberry Pi Foundation Logo

Build the future, block by block, block by block

Blockly is a library for visual programming that uses drag-and-drop blocks. It's the engine that powers the most popular coding education programs worldwide.

Applications to attend Blockly Summit 2026 are now open!


Join us in-person on June 3-4 at Murray Edwards College in Cambridge, UK and discover the best of Blockly.

Blockly has a new home.

After more than 12 years of growth at Google, the Blockly open-source project became an independent project under the stewardship of the Raspberry Pi Foundation.

The Blockly open source project and key Blockly team members transitioned to the Raspberry Pi Foundation.

Why Blockly?

Blockly is the preferred choice for platforms aiming to deliver versatile and intuitive coding experiences.

Robust library

The Blockly library is open-source to all. It offers a comprehensive suite of APIs and tools, empowering coding platforms to provide a customizable environment for their unique requirements.

Visual interface

The Blockly editor uses interlocking, graphical blocks to represent code concepts like variables, logical expressions, loops, and more. Users apply programming principles without worrying about syntax.

Cross-platform

A platform-agnostic library, Blockly is preferred by coding platforms seeking consistency, flexibility and convenience. Blockly is compatible with major browsers and works on both web and mobile.

Transition FAQ

Will Blockly still be free and open source?

Yes. Both Google and the Raspberry Pi Foundation are committed to Blockly's core library remaining free and open source under its existing Apache 2.0 license. Raspberry Pi Foundation is committed to the long-term growth of Blockly's open code base and developer community.

What does this mean for my existing projects using Blockly?

Nothing.  Developers do not need to make any changes to their existing projects. Blockly's core library will continue to be maintained and developed as you would expect.

What will happen to Blockly's Community Forum and website?

The Blockly Community Forum will remain on its current Google Group.

Blockly's developer documentation, website and summit content will be migrated to a consolidated site on blockly.com.

We plan to launch this by March 2026. We'll let folks know on the Blockly Community Forum when the new site and its redirect pages are up.

Will the Blockly Summit happen in 2026?

Yes. Join us in-person on Wednesday, June 4 and Thursday, June 5 at the Paula Browne House Conference Centre, located at Murray Edwards College on the University of Cambridge campus. Learn more about Blockly Summit 2026 here.

How do I contact the Blockly team?

The Blockly team continues to actively monitor and respond to the Community Forum. If you need to reach the Blockly team directly, email support@blockly.com
