Edgemesh is so ideally situated. Actually going headless is a months long project that requires hours of development and essentially rebuilding your site. Edgemesh works out of the box.
Without Edgemesh, I don't think we would have scaled as far as we have...we would've seen the pain of scaling two years ago, because of the amount of traffic we received.
What I like about Edgemesh is that we didn't have to make a lot of changes to our website. With a little bit of code adjustment - a really minor amount - we flipped a switch and now have the same benefits and controls that we were looking for with headless.
