I love this ! i was using an airtable alternative to store my data, and i found BLUE , and it is a great alternative, with flexibility in terms of the automation that u can set. Sometimes it may take some time to load ( the down side) but it's still okay, and if u are using trello (free) like me, to store data.

u can view my blue demo & review youtube video here

Using blue will be a great choice because in trello free, u can view ur data in the form of spreasheet ( like airtable)

but with BLUE, u can to view and export ur data in csv format.

Hope this review helps others
