There weren't many free and open source 3D physics engines to begin with. The ancient forefathers are ODE, Bullet and Newton Dynamics (all first released in the early 2000s), then nothing(?) for nearly two decades until Jolt in 2021 and now Box3D.
replyAny addition to this small and exclusive list is very welcome :)

replyI remember trying this back in 2004 or so when i was making my first real 3D game engine, but i ended up abandoning it because i was trying to use it on 64bit Linux and the source code had typecasts between pointers and (32bit) ints all over the place :-P.
That was fixed later and apparently the engine was used in a few commercial games during the 2000s and early 2010s.
NVidia made PhysX open source in 2018, and it was free to use before.
replyThere’s some ODE/more dimensions/PDE pun in here, for somebody better than me in physics or at least funnier.

replyBox2D is still pretty darn good! Definitely recommended for 2D physics game projects. The C APIs for Box2D and now Box3D are just so nice to work with.
replyi remember being hooked on Incredibots back when that was still a thing! that was how I heard about Box2D way back.
replyWell hello random IncrediBots-remembering person! Such good times with an oddly wholesome and welcoming community.
replyI spent many of my teenage and early adult years trying to replicate it in HTML5. Finally got the Open Source version of IB2 largely ported during COVID: https://github.com/JoshTheDerf/Incredibots-2-HTML5-Open-Sour...
I used Chipmunk2D a little back in the day, found it easier to use for whatever arcane thing I was doing.
replyBox2d was somewhat recently rewritten in c and the api is improved, fwiw.
