How does your project differ from Metabase[0]?
I'm watching videos on their website and it looks like, that Metabase uses browser as a front end, SkyAlt is native. I'm not sure If you can create/edit tables/columns in Metabase, it looks more like a "import data and create dashboards". SkyAlt is more like Airtable meets Tableau.
This will lead to the option to build internal tools. Adding dashboards and writing to remote databases should be easy to program, but right now I focus on stability, usability and documentation for current features.
