Basic lambdas work. For headless, just use *VM.js. Drag and drop in tree UI html. Future versions will likely not be backward compatible cuz still changing the opcodes. Next step is to JIT compile to javascript, then to GPUjs andOr GLSL directly. See "transpile" code for where to add on to that. This could be used as it is for lambda research (fork it as is and dont change the opcodes in that fork). Open index.html to see a few UIs available.
