Use a few basic building blocks to build complex API endpoints. Connect to your MongoDB or Firestore database. Setup authorization with JSON web tokens, payments with Stripe, email with Nodemailer or SMS with Twilio.



No deployment is required. You are live!

There is no need for managing servers, version deployments, 3rd party libraries packages etc. The endpoints of the nocode backend are automatically live and can be called from your frontend right away. There is a Debug panel to test the endpoints for different Headers and Body parameters.

Data Ownership

100% control of your data

Data stored can be stored in MongoDB, Firestore or EasyDB. That means that you can view and edit your data from MongoDB compass or OpenBase or Firestore cloud dashboard. At the same time you can build any other app to connect to the database as you would if you were building with code.

Coming Soon: SQL support (Postgres & MySQL)

Authentication, databases, payments and more.

Every endpoint requires a Request block for receiving the request and getting the HTTP headers, query params and body and one or more Reponse block for sending out data. There are the Bcrypt and Jwt blocks for json web token authentication, Stripe block for handling payments, a Code block that supports Javascript for more complex needs and database integrations such as MongoDB, Firestore, EasyDB integrations. SQL support (Postgres & MySQL) is coming soon.

User Stories

Things our users say

It's just simple drag and drop and you build a backend which used to be the hardest bit about building software.

The dev team really likes how Diagram plays nice with our existing backend. We don’t use Diagram for everything but for things we do it's at least 90% easier.

It's sweet you can test product ideas that fast. My new favourite nocode stack is Webflow + Diagram + MongoDB. I call it WDM!
