is an online chat website that pairs random people from around the world together for webcam-based conversations.
Visitors to the website begin an online chat (text, audio and video) with another visitor.
At any point, either user may leave the current chat by initiating another random connection.
As the number of active users grew, Ternovskiy has had to rewrite the entire code to cope with the load, the management of which being the most challenging part of his project.
Despite the expansion of the service, he still codes everything on his own.
Ternovskiy sought help from his longtime friend Vlad Kostanyan, who helped him with his side projects.
One informal study published in March 2010 shows that nearly half of all Chatroulette "spins" connected a user with someone in the USA, while the next most likely country was France with 15%.
On average, in sessions showing a single person 89% of these were male and 11% were female.
8% of spins showed multiple people behind the camera.
1 in 3 females appeared as such a group, and 1 in 12 males.
A user was more likely to encounter a webcam featuring no person at all than one featuring a sole female.
1 in 8 spins yielded someone apparently naked, exposing themselves or engaging in a sexual act.
A user was twice as likely to encounter a sign requesting female nudity than to encounter actual female nudity.
The website uses Adobe Flash to display video and access the user's webcam.
