Justin Rhee(@rheejust):Starting today, you can host sandboxes for running agents and untrusted code in your own AWS account. Self-hosted sandboxes on Porter are now officially available for all users. Many companies from our YC-only beta including @atobHQ, @MaingenInc, and startups in the current batch like @lettercompany have been running production agents on Porter sandboxes for a few months now. As with all of Porter's infra primitives, everything can be seamlessly run within your own AWS account (and using your existing cloud credits).
