Table Apps alternatives

This is the most revolutionary app I've used for my elementary school's data management. Easy to use and incredibly powerful and flexible. The learning curve is minimal for the non-engineers in my team. They're used to Excel and Sheets so they don't have to learn a whole new UI to see and search data. The devs in the team have access to the API so we've been able to integrate it seamlessly into our Customer Portals so that the backend is basically a collection of Google Sheets while the front end is a full-featured Web App. What a revolution this has been!
