Blacksmith.sh has been great for us. Massively sped up tests and a huge improvement for Docker builds over both Actions and Google Cloud Build.

Only downside is they never got back to us about their startup discount.

hey there! blacksmith solutions engineer here :) love to hear we've helped speed up your tests and docker builds!!

could you shoot me your GH org so I can apply your startup discount? feel free to reach out to support@blacksmith.sh and I'll get back to you asap. thanks for using blacksmith!
