PebbleOS, running in your browser: the firmware of a native virtual watch, built as WebAssembly. Pick the watch from the list, then click its buttons, or the screen and then use the arrow keys (left is back, right is select); on watches with a touchscreen the mouse is a finger on the screen.
Note
The playground is not part of this build of the documentation.
Nothing is saved: the watch starts afresh every time the page loads. To run the same build yourself, see Native simulator.
