Both of the systems are low-code/no-code development platforms.
Both of them can handle your data in proper a structure.
When to choose which one? Here are the main differences:
While Airtable is great for working with simple tables, Tabidoo is more suitable when you require better control of data validity.
In Tabidoo, you do not pay for every single user. In Tabidoo your price depends only on the data volume. In Airtable you pay $20 per user if you want to have control over user access.
There is no limit to the features you can use in Tabidoo. Features in Airtable depend on your plan.
Unlike Airtable Tabidoo supports installation in your data center (on-premise).
In Tabidoo, you can use any features even as a free user. There is a limit on data amount, number of API calls. However every feature is accessible to all users.
Airtable offers different features according to the selected plan. Even such a basic thing like permissions is paid. Enjoy.
The report designer in Tabidoo is incredible. It is very intuitive and as powerful as professional tools.
There are some ways how to get printed reports from Airtable. But it is still workarounds.
Tabidoo, as a significantly smaller company, has nice and friendly support. All of the development is driven by user feedback.
Tabidoo is not only one of the Airtable alternatives.
It is different in many ways. Sometimes better, sometimes not.
Every case is unique - as your business.
