Building the future with Blockly at Raspberry Pi Foundation

Building the future with Blockly at the Raspberry Pi Foundation

By Rachel Fenichel, Blockly

Today we're announcing that Blockly, Google's open source library for drag-and-drop programming, is moving to the stewardship of the Raspberry Pi Foundation on November 10, 2025.

Since its creation at Google in 2011, Blockly has grown from a passion project to a standard for visual programming. Educational platforms such as Scratch, MakeCode, and LEGO Education use Blockly to remove barriers to entry into the world of programming. Blockly's move to the Raspberry Pi Foundation reflects close alignment with its education-focused mission.

The Raspberry Pi Foundation is one of the world's leading non-profits dedicated to advancing computing education. This move is designed to sustain Blockly's long-term stability and continued innovation as a foundational tool for block-based coding and computer science worldwide.

We are delighted that the Raspberry Pi Foundation will be the new home for Blockly, the world's leading open source library for visual programming. We are committed to maintaining Blockly as an open source project and look forward to working collaboratively with the amazing community of developers and educators to increase its reach and impact in the years to come.

– Philip Colligan, Chief Executive at Raspberry Pi Foundation

Blockly's growth, evolution, and success rest on a foundation of support and investment in open source software from Google over many years. Google.org's support for Blockly's future at Raspberry Pi Foundation strengthens the ecosystem built on block-based coding, fostering greater innovation and expanding access to computational thinking for people around the world.

Looking forward, I'm excited for our future collaborations with the Foundation's world-class research, learning and product teams. We are committed to Blockly's ongoing development, including both feature development and support. Blockly will continue to be free and open source, and existing projects do not need to change anything about how they use Blockly.

Blockly Summit 2019: Rendering, Accessibility, and More!

It has been over eight years since we started work on Blockly, an open source library for building drag-and-drop block coding apps. In that time, the team has grown from a single developer to a small team and a large community. Blockly is now a standard in the CS education space, used by Scratch, MakeCode, AppInventor, and hundreds of other developers to enable tens of millions of kids around the world to create and express themselves with code.

But Blockly isn't only used for education. The library provides everything an app developer needs to create rich block coding languages and is highly customizable and extensible. This means Blockly is also used by hobbyists and commercial companies alike for business logic, computer games, virtual reality, robotics, and just about anything else you can do with code.


The work we do on Blockly wouldn't be possible without the many folks who contribute back with code, suggestions, and support on the forums. As such, we were very excited to welcome around 30 members of the Blockly open source community to our second annual Blockly User Summit and to be able to make all of the talks available online!

The summit spanned two days in October and included 16 talks, over half of which were given by external contributors, and a Q&A with the Blockly team. The talks covered everything from Blockly's brand new rendering framework and building custom fields to explorations in performance and debugging block code. Check out the full playlist.

We also held a hackathon on the second day of the summit, with quick start guides for using our new rendering and accessibility APIs. If you're new to Blockly and you'd like a good starting point, take a look at our CodeLab and if you build your own cool demo let us know on our forums.
