You seem to be missing Coda (
https://coda.io ) which (in my experience) comes remarkably close to “Excel with data powers”. Think of Notion’s document editing and tables, but with _much_ more power, a proper formula language, UI widgets, etc. The Coda team have churned out a ton of amazing features in remarkably short time.
The main drawback I’ve encountered: no obvious way to separate code and data. I can’t find a way to version/clone one without the other while keeping the data in Coda. However there are plenty of integrations with external data sources, so keeping a chunk of the data external may be the best way.
EDIT: Oops, forgot to thank you for creating this amazingly comprehensive sheet. I’m looking for a similar thing myself: a self-hostable CRM for a small team that wants some flexibility around custom fields and automation but doesn’t need most of the other common CRM features. My current plan is to try AppSmith, but there are a bunch of entries in your sheet that I haven’t seen before. Thanks again!
