Honorable Mention
The 0.0.2-beta-legacy branch includes a deprecated TUI for querying cloud costs across providers. It is no longer supported due to changes in the pricing data model, but remains noted here as an honorable mention.
This CLI also has a TUI mode, I just disabled it for now and am still working on it
