I love the demo. I love the tooling.

Demo tips: Name your queries. Following along "query1, query2, query3" is confusing. You should following best practice (where it makes sense) during demos, and you're definitely not doing it.

The selling point of this tool shouldn't be for the developer, it should be for the manager. So add some "here are some other examples of tools we've created in a similar amount of time through a similar process" - then have UX's for different companies, industries, regions.

Non-technical management need ideas. This demo doesn't give it beyond "hey look you can create a button to update a table". So what? Every ERP and CRM SaaS has that!
