The end of an era: Twitter will forever block third-party clients (like Tweetbot)

After days of uncertainty and a half announcement, Twitter updated its terms of use and confirmed that it will not allow third-party clients. The company quietly changed the Adeveloper sane, a contract that states what can and cannot be done with the API. The document now includes a clause that prohibits the creation of products similar to the official application.

The update is found in subsection A of Reverse engineering and other restrictionswhich belongs to the section Restrictions on Use of Licensed Materials. It establishes that it is not allowed use or access the licensed materials to create or attempt to create a substitute or similar product or service to the Twitter Applications.

The company confirmed yesterday that the blocking of third-party clients was due to enforcing their long-standing API rules. Indeed, the terms have been around for years, however, Tweetbot, Twitterrific and other applications were allowed. The version in force at the time of publication of the tweet did not contain the new clause, as evidenced a copy stored in Wayback Machine.

Twitterrific withdraws its applications and charges against Twitter

The restriction comes into effect as of today, so all clients will stop operating. At the time of writing this note, only Twitterrific has announced the end of its service. A post on Iconfactory’s blog communicates that the applications for iOS and macOS have been removed from the App Store. The company also charge against Twitter for the unfortunate way things happened.

We’re sorry to say that the app’s sudden and undignified disappearance is due to an unannounced and undocumented policy change by an increasingly capricious Twitter, a Twitter we no longer recognize as trustworthy or want to work with anymore.


The company warns that the loss of revenue from Twitterrific will seriously hurt business, and that the thousands of refunds will be devastating for a company of its caliber. Craig Hockenberry, Director of Iconfactory, went straight for the jugular of “Space Karen” (Elon Musk).
