The two companies have merged to form a new business, Wisden CricInfo, that will eventually result in the creation of a combined website featuring the best content from both sites.
The combined site will be the world's largest and most comprehensive cricket website, and one of the biggest of all sports sites on the internet, it claims, with more than 19m unique users.
Said Robin Bevan, Wisden CricInfo's new chief executive officer: "We will be combining Wisden's editorial flair and depth of content with CricInfo's extraordinary breadth of live match coverage, and jointly develop new products and services for the ever-growing online cricket audience."
Access to most of the site content will remain free of charge, with both parties' respective subscription services being retained pending the launch of a new subscription service later in the year.
"CricInfo has built its business based upon free access to content. We certainly don't plan to change that - but we will look at introducing a subscription element for certain types of premium content later in the year," said Robin Bevan.
No financial details of the venture will be disclosed.
Wisden Online and CricInfo are joining forces to create the world's largest dedicated cricket website and online business.
