Meet Webiny - Serverless CMS
Webiny is open source, powered by React, GraphQL, Node and MongoDB.
We just launched on Product Hunt (https://www.producthunt.com/posts/webiny-serverless-cms) and are looking for beta users and feedback.
We also offer a paid managed hosting. During beta all packages are 100% free of charge, and afterwards beta users gets 50% off for the first 12 months.
If any of your are in London - I'm happy to meet up and discuss your feedback over a beer or coffee :)
