I agree, and unclear why you're being downvoted. From the title I thought that Render must be a database company that built a database protocol-compliant with Redis. It took a while of searching around their blog, github, and careers page to understand that isn't what they do.
Generally “me too” HN comments are frowned upon, but I also clicked because I thought this was a rewrite of a redis-compatible offering that perhaps offered something like zero-click sharding or something.
Right now it sounds as if it's a redis competitor, aka clickbait
