I just wanted to share this great codeless backend platform that works great with Retool. It’s called Backendless and they have a guide for integrating specifically with Retool. They have a great realtime database, tons of APIs, and a codeless API and backend logic builder. I’d highly recommend checking them out!
Here’s the guide: https://backendless.com/how-to-integrate-retool-with-backendless/
