I mentioned it recently[0], but this looks like a very good topic to plug our new database, Seafowl, that we released last year [1]. It also uses Apache DataFusion (like IOx) and separates storage and compute (like Neon, Snowflake etc) but is designed for client-side Web apps to run analytical SQL queries over HTTP (using semantics that make the query results cacheable by browser caches and CDNs). This makes it really useful for things like interactive visualizations or dashboards.
We're currently doing a lot of work at Splitgraph to reposition the product around this "analytics at the edge" use case, with usage-based billing, eventually moving our query execution from PostgreSQL to Seafowl.
