Define GraphQL schema

Optionally define security rules.
Use our interactive documentation if you are not familiar with GraphQL yet!

Deploy API to the cloud

API is available on our subdomain after deployment (mycoolapp.deffun.io, for example), but you can change it to your domain (mycoolapp.com, for example).

Customize using serverless functions

Write a serverless function using the language of choice, deploy it to AWS Lambda, Azure Functions or another provider and integrate it into your code.
Want to avoid network delays? You can do it using Polyglot VM.

Scale as you GO!

From dozens of users to millions - scale your API when necessary!
