OpenOrange claims 34.8x lower S3 costs for agent workloads via Rivet's storage engine

Developer NathanFlurry introduced OpenOrange, built on Rivet's storage engine, claiming 34.8x lower S3 costs versus celld's architecture for agent workloads.

The core argument: S3 storage is cheap ($0.023/GB/month, 10x cheaper than replicated EBS), but per-operation pricing explodes costs for write-heavy workloads — writing one object per second for a month costs $13 on S3 versus near-zero on EBS. That makes agents, workflows, background jobs, and session stores expensive to run on S3.

OpenOrange sidesteps this with a storage engine Rivet built for scaling the actor model. X user vincentkoc noted he thought MinIO had this space mostly to itself.
