It seems likely that Phoenix can run with minimal resources; internally, the team uses 2GB RAM and a single vCPU for hosted Phoenix. There is no official minimum hardware spec in the documentation, but this configuration appears to be a reasonable starting point for most use cases. You can scale up resources or run multiple stateless Phoenix containers as your workload increases, since Phoenix is designed to be stateless and can horizontally scale with a shared Postgres backend if needed.
Would you like more detail on scaling strategies or production best practices?
