Sidechat

Sidechat is an anonymous, campus-based social networking app for college students, built by Flower Ave Inc in New York City and backed by Canaan Partners. Students verify with a school email to join their college's private, location- and campus-scoped community where they post text, images, and polls, vote, and chat anonymously in a Reddit-like feed. Sidechat launched in early 2022, acquired Yik Yak in 2023, and operates primarily as an iOS consumer app. It publishes no official public API, developer portal, SDK, or OpenAPI surface; this profile captures the company's public web presence and identity for the API Evangelist network.

Sidechat is profiled on the APIs.io network. Tagged areas include Company, Social, Anonymous, Community, and Messaging.

Sidechat’s developer surface includes support, signup flow, and 4 more developer resources.
