The code behind our next-generation version of hEngine is now publicly available in our
hash monorepo on GitHub. You can find this at https://github.com/hashintel/hash/tree/main/packages/engine
This is an entirely new hEngine, distinct from that currently in use in both hCore and hCloud. Our intention is to eventually migrate both of these services over to the new, public hEngine. Currently it is less performant than the engines powering both hCore and hCloud, but for reasons well-understood which we intend to address before cutting a v1 release of our unified, cross-target hEngine.
