Long story short
Spring Engine is an ancient RTS engine that spawned several projects, one of them was a remake of Total Annihilation in this engine, with balanced changes, called Balanced Annihilation Reloaded (BAR). The project got track and started to do its own thing, and they changed the name to Beyond All Reason. Now the Spring Engine fork is called Recoil and has a lot of improvements all in OpenGL
Zero-K is a fork of the Spring Engine and its also its own thing. Its based on Total Annihilation but not quite, has its own QoL and is drastically different. Playing them both, BAR is the much more polished and known project but ZK is free as well on Steam and some people like its differences. If you're an RTS lover just give them both a go.
