LONDON  As the WikiLeaks founder Julian Assange fights extradition to Sweden to face allegations of sexual wrongdoing, a dozen of his former colleagues are creating an alternative Web site for leaks to be governed by what they characterize as a revised vision of radical transparency.

The new organization, OpenLeaks, will begin work in earnest this summer, said Herbert Snorrason, an Icelandic programmer who is involved. It aims, he said, to avoid the “influence of a single figurehead” by refusing to handle documents itself. Instead, it will act as a neutral conduit to connect leakers with media and human rights organizations.

OpenLeaks emerges from the ashes of a struggle between Mr. Assange and many of his closest associates last September. About a dozen members of WikiLeaks left that month, accusing Mr. Assange of imperious behavior and of jeopardizing the project by conflating the allegations of sexual wrongdoing, which he denies, with the site’s work. The defectors, Mr. Snorrason said, decided to start their own project.

“It’s no secret that we had disagreements with how WikiLeaks was being managed,” he said, “and a large part of what we hope to accomplish with OpenLeaks is to avoid those problems.”
