This is great for running challenges as you can hold and manipulate the data however needed. I use it as an advertising CRM very effectively. Displaying info where a calendar is involved is very useful as it means I can see the dates in date format rather than text. The scenario where it's less suited is where you need two sheets or ways of displaying a sheet next to each other (as far as I've found) - Such as the way Grist displays widgets.

Stackby
- How a stack is displayed after embedding into another page using their provided script. Currently, it shows the rows in a completely different layout.
- Currently, no support for custom domains.
- Cannot customize cell colors. Currently, can only change colors for predefined texts within a cell.
- Lack of integration with Google ads or YouTube ads. Currently, only integration with Facebook ads exists (although I believe more will be added later).

ContactOffice offers four plans for its Individual version. ContactOffice has more supported Integrations than Worksection.

Airtable - better all round than Stackby but way more expensive (actually not all round - Stackby you can actually backup unlike Airtable)Infinity - bought this and wished we hadn't. Its data structures and terminology are super-confusing and it's really hard to set upNotion - not strong enough as a database but very lovely to look at!
