Blockly is an open-source visual programming editor that uses drag-and-drop blocks. It powers the most popular coding education programs in the world.
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.
As of November 10, 2025, the Blockly open source project and key Blockly team members transitioned to the Raspberry Pi Foundation. This transition is designed to drive Blockly's long-term stability, and continued innovation as a foundational tool for block-based coding and computer science education worldwide.
Blockly is the preferred choice for platforms aiming to deliver versatile and intuitive coding experiences
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.
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.
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.

This investment follows Google.org's model of incubating powerful educational innovations and then positioning their long-term, sustainable impact. This support strengthens the ecosystem built on block-based coding, fostering greater innovation and expanding access to computational thinking for people around the world.
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.
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.
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.
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.
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
