Started in 2010, Kleki aims to be the goto tool for quickly creating fun paintings. It is universally accessible through the browser without any installation and allows anyone to start sketching immediately. Kleki is open-source, community funded and is developed & maintained by the programmer/artist bitbof. This site believes that the activity of making art should not be intruded by ads. Kleki is inspired by early web applets for drawing like Oekaki Shi-Painter and Lascaux Sketch. Kleki's "sketchy" brush is inspired by Harmony.

Select tool affects other tools (e.g. brushes)
Select tool > transform behaves like transform dialog
Recovery for embedded version of Kleki/Klecks
