keWlers is a Finnish demogroup, formed in the early 1990s, originally called Mewlers. After smaller releases such as Tripfish 2 or Another High-Caliber Mechanical Complication, their breakthrough came in 2002 when they released their critically acclaimed demo Variform at Assembly 2002. Despite only achieving third place, the demo became one of the most widely known and top rated demos ever released, winning three Scene.org awards. Further major demos to be released later included Protozoa (ranked 6th at Breakpoint 2003) and A Significant Deformation Near The Cranium, released at Assembly 2003. Kewlers have been nominated for at least one Scene.org Award every year, except for 2004. The group disbanded for a while in 2006 directly after the release of their final demo, 1995. But since 2010 Kewlers have returned from their hiatus, with possibly Variform 2, released at Revision 2012, as their most influential demo since their comeback.

keWlers are infamous for their outspokenness – their logo contains a stylized middle finger and their official slogan is "Kewlers suck!" – likely to be originating from crowd cheers at the Scene.org Awards gala at Breakpoint 2003 – which they now use and prefer as a friendly greeting. It is also common for other demogroups to, instead of sending greetings, send "fuckings" to Kewlers as their sign of gratitude and respect. Most of the members' handles are in fact "Kewlers-nicks" besides their original, possibly more known demoscene-handle.

Since 2004, the number of Kewlers demos has decreased, and after the release of We Cell at Assembly 2004 the group hinted on their website to cease any further activities. With the release of their Assembly 2006 demo 1995 (in cooperation with mfx), the group officially acclaimed to call it quits.

However, in 2010, Kewlers returned to the Assembly demo competition, releasing 'Devolution', which earned 4th place. In 2011 they released 'Fermion' at Assembly 2011, which also received 4th place.

At the Assembly 2012 wild demo competition, Kewlers released their first Android based demo called Rrhoid, which earned 3rd place. In 2013 Kewlers kept on releasing mostly Android demos, with most recently NVite, an invitation for NVScene organised by nVidia and scene.org
