Cofounder of Budibase here - an open source low code platform.
I feel if you are going to do this, you should leave it to an independent party. The fact you work for DronaHQ makes me feel there might be biased in the tools evaluation.
There is a future for specific use cases. For simple CRUD apps, workflows, admin panels there is a future. For SaaS applications, I am not as sure due to its feature-evolving / bespoke nature.
I really like the idea, and as the founder of Budibase (https://github.com/Budibase/budibase) an open source low code platform for building internal tools, I wanted to show my support.
This is something the market has needed for a while. We integrate with Airtable and when chatting to a lot of users, they have voiced their concerns around a lack of Open Source alternative - most migrate to Budibase's internal tables, but some, mostly non-technical users, prefer the spreadsheet interface. Going forward, I'll recommend your tool, and I wish you all the best :-)
