Cohost (stylized in all lowercase letters as cohost or cohost!) was a social media website publicly launched in June 2022. It was owned by a not-for-profit software company named Anti Software Software Club.
On September 9, 2024, it was announced that it would enter a read-only state on October 1, 2024, and be discontinued at the end of 2024. Registration was closed on the day of the announcement. The shutdown was later postponed to accommodate an archiving effort by the Archive Team. The website was shut down on January 12, 2025.
