Blockly development began in summer 2011. The first public release was in May 2012 at Maker Faire. Blockly was originally designed as a replacement for OpenBlocks in App Inventor. Neil Fraser began the project with Quynh Neutron, Ellen Spertus, and Mark Friedman as contributors.
The default graphical user interface (GUI) of the Blockly editor consists of a toolbox, which holds available blocks, and where a user can select blocks, and a workspace, where a user can drag and drop and rearrange blocks. The workspace also includes, by default, zoom icons, and a trashcan to delete blocks. The editor can be modified easily to customize and limit the available editing features and blocks.
Blockly is used in several notable projects, including:
- MIT's Scratch, visual programming environment for education
- MIT's App Inventor, to create applications for Android
- Blockly Games, a set of educational games that teach programming concepts such as loops and conditionals
- Code.org, to teach introductory programing to millions of students in their Hour of Code program
- RoboBlockly, a web-based robot simulation environment for learning coding and math
- Wonder Workshop, to control their Dot and Dash educational robots
- KodeKLIX, to control their snap-together electronic components
- PICAXE, to control their educational microchips
- SAM Labs, in STEAM learn-to-code education solutions
- Blockly, helps kids learn about coding for education
- Web-based using Scalable Vector Graphics (SVG), no Flash
- Support of major web browsers including: Chrome, Firefox, Safari, Opera, Internet Explorer (IE)
- Mobile support on Android and iOS
- Support for many programmatic constructs including variables, functions, arrays
- Minimal type checking supported, designed for weakly typed languages
- Easy to extend with custom blocks. Use the Block Factory to make new blocks
- Clean code generation
- Step-by-step code execution for tracing and debugging code
- Localised into 50+ languages
- Support for left-to-right and right-to-left languages
