Thank you for shoutout. (Disclaimer : Founder here)

Yes, NocoDB[1] allows to transform your own databases into Airtable like smart-spreadsheets. It is easy to get started - please try it out.

Thanks for the pointer, this seems really neat! Although from what I can tell it primarily provides a data interface geared towards relational databases (or other record-oriented data sources).

I played around a little and am missing actual spreadsheet functionality - like the ability to do calculations, or other manipulations that you could do on tabular data in Excel/Google Sheets (and presumably Rows). Am I missing something?

Yes, its geared towards part-spreadsheet part-database space. We're similar to Airtable mostly.

You can do calculations by creating a column with formula field.

Any idea when they will have a decent implementation of forms (and maybe even subforms) with customized layouts? Last I checked it was ~on the road map.

Hey, Form views were made available with 0.11.42 (5 weeks ago). It can be customised with fields you need.

An error occurred on client - that's all I see. Either it's adblock or my outdated browser, but, in any case, it's a no go.

Founder here - what browser & OS is it ?

Hi, it's Ubuntu & FF50.1. Front page works now, but sign-up is empty for me. Anyway, I understand that supporting older browsers is not an easy task... probably. So, don't mind me.

Interesting... it doesn't seem to allow putting charts next to the spreadsheet though

That's coming literally today/monday :)

charts are live now
