I assume you've seen https://tug.org/levels.html or similar.
LaTeX is a macro package, and therefore works with any engine which
provides the required primitives (built-ins). Today, that set is Knuth's
TeX + e-TeX + 'pdfTeX extensions'. There are a number of engines that do
HiTeX is rather new and experimental, but the others are all widely used.
All except LuaTeX are written in WEB and converted using web2c
(https://tug.org/texinfohtml/web2c.html) for building binaries. LuaTeX
is written in C directly.
Whilst TeX Live is a major TeX system, there is also MiKTeX (very
heavily used on Windows) and KerTeX (restricted to a BSD license and
therefore suitable in places that GPL code is not acceptable).
