How to find a list of live and upcoming Twitter spaces?

Question

I ask this question because about a year or so ago, I distinctly remember finding a website with a simple UI, that listed in a tabular format all live and upcoming twitter spaces, that was filterable by topics and sortable by speakers and viewership. It was more of a "hacker" app, not main stream, regardless if anyone remembers that app, are there any alternatives?(my google-fu gets nothing)

Probably got killed alongside the free API. There's very little financial incentive to support Twitter at the prices they're demanding.
