Our aim is to create an open data ecosystem for reviews of places, companies, websites, books, and more. We provide open-source infrastructure that enables any application or website to integrate a reviews layer, and to benefit from a shared data pool that is created by the combined user base of all participants.

Mangrove provides
  • A technical standard to ensure interoperability
  • An open-source API
  • An aggregation algorithm to clean and filter the data
  • A downloadable open dataset licensed under CC-BY-4.0
Mangrove is a non-profit service hosted and supported by a community of businesses, developers and interested parties around the world.

We would be happy to support you to integrate Mangrove into your application or website. Get in touch in our Riot chat or by email (mangrove(at)planting(dot)space). Or just try out Mangrove in the demo web app.
