SkyscraperCity, also known as SkyscraperCity.com, is the world's largest online forum on skyscrapers and urban related topics.

[2][3][4][5][6] The website, which currently runs on XenForo, was founded in 2002 by Dutch economist Jan Klerks running on vBulletin,[2][7][8][9] in order to share and solicit comment on urban development in Rotterdam.

[10] It gradually expanded to include other city and country subforums, eventually encompassing the entire world.

[3] In 2018, SkyscraperCity was acquired by VerticalScope and the forum was migrated from vBulletin to XenForo in 2020.

[11] The site works by allowing members to add photos and other details to the website.
