There's something about this company's design and font/logo choice that makes it "feel" exactly like Robinhood.
Also, this feels really similar to another project that launched on HN this month, https://news.ycombinator.com/item?id=25059133 (although Supabase focuses more on scalability, while Etebase focuses more on privacy?). Might be some interesting discussion there.
I haven't ever used firebase, nor Etebase, but the new(?) project on the front page may interest you:
