I work on geospatial apps and the software I think I am most excited about is https://felt.com/. I want to see them expand their tooling such that maps and data source authentication/authorization was controllable by the developer, to enable tenant isolation with proprietary data access. They could really disrupt how geospatial tech gets integrated into consumer apps.

This article doesn't acknowledge how niche this stuff is and it's a lot of training to get people to up to speed on coordinate systems, projections, transformations, etc. I would replace a lot of my custom built mapping tools with Felt if it were possible, so I could focus on our core geospatial processes and not the code to display and play with it in the browser, which is almost as big if not bigger in terms of LOC to maintain.

As mentioned by another commenter, this DuckDB DX as described is basically the same as PostGIS too.
