I recently set up AWS Github runners with this terraform. It works well and you don't have to pay any extra in addition to AWS.
Definitely linking OP to my team now.
With Depot, we're moving towards deeper performance optimizations and observability than vanilla GitHub runners - we've integrated the runners with a cache storage cluster for instance, and we're working on deeper integration with the compute platform that we built for distributed container image builds - as well as expanding the types of builds we can process beyond Actions and Docker, for instance.
But different options will be better for different folks, and the `philips-labs` project is good at what it does.
