Tumblr is transitioning to WordPress following its 2019 acquisition by Automattic for $3 million. Automattic plans to improve Tumblr’s platform and revenue while keeping its unique posting experience intact. The move will allow improved sharing of features between the two platforms and take advantage of WordPress’s open source developments. Automattic acknowledges the technical challenge of migrating half a billion Tumblr blogs but is committed to the task. Despite Tumblr’s financial struggles, Automattic sees potential in the platform and aims to revitalize it through the migration. The transition’s timeline and roadmap remain unclear, but Automattic is confident in the benefits of moving Tumblr to a WordPress back end.
