Heroku was initially developed by James Lindenbaum, Adam Wiggins, and Orion Henry for supporting projects that were compatible with the Ruby programming platform
Rack. The prototype development took around six months. Later on, Heroku faced setbacks because of a lack of proper market customers as many app developers used their own tools and environment. In January 2009, a new platform was launched which was built almost from scratch after a three-month effort. In October 2009, Byron Sebastian joined Heroku as CEO. On December 8, 2010, Salesforce.com acquired Heroku as a wholly owned subsidiary of Salesforce.com. On July 12, 2011,
Yukihiro "Matz" Matsumoto, the chief designer of the
Ruby programming language, joined the company as Chief Architect for Ruby. That same month, Heroku added support for
Node.js and
Clojure. On September 15, 2011, Heroku and
Facebook introduced Heroku for Facebook. At present Heroku supports
Redis databases in addition to its standard
PostgreSQL. On April 7, 2022, Heroku suffered a significant security intrusion when attackers were able to obtain an access token for a Heroku account that was used for automation purposes. Heroku confirmed that the attack accessed
OAuth bearer tokens used for integration with
GitHub and
salted and hashed customer passwords in May 2022. In August 2022, Heroku announced that its free plans would be discontinued, citing fraud and abuse as reasons for the change. In March 2024 at Kubecon Paris, Heroku announced that it was replatforming onto
Kubernetes. On February 6, 2026, Heroku announced that it would be transitioning to a new engineering model with a focus on security, reliability, support and stability rather than introducing new features. It mentioned that Enterprise Account contracts would no longer be offered to new users. It has emphasised that Heroku remains fully supported and existing customers would not be affected by this change. == Etymology ==
