OpenFeed is a social network built as an open platform. Everything runs through one public JSON API with an OpenAPI 3.1 spec, and our own app at openfeed.eu uses nothing else. Build your own client, bring a space's feed into your community site, or make a tool on top of public feeds. Users sign in once on openfeed.eu and bring their account to every app. Try every route in the playground, no account needed. Chronological, ad-free, no profiling, hosted in the EU.
