The comedies will be available to watch on the BBC Three blog a week before their television debuts.
The first show, Inn Mates, stars Neil Morrissey and Coming Of Age's Joe Tracini and focuses on a group of friends who spend time at The Friendship Inn. The programme is already available to watch on the website and will air on BBC Three on Monday at 9pm.
The Klang Show, which will be published on the blog on Monday, stars The Inbetweeners' Greg Davies, Steve Hall and Marek Larwood. The show has been described as "stupid comedy for grown-ups" and will see the comedians take part in various challenges.
Finally, The Adventures Of Daniel will be available to watch on the blog from Monday, August 16. The pilot follows the life of 19-year-old Scottish comedian Daniel Sloss.
Earlier this year, BBC Three published its pilots Pulse, Stanley Park and Dappers online before their television premieres.
