   Flexprice▲240

   Hi HN, We're building flexprice, a monetization platform that helps making usage-based, credit based and hybrid pricing easier and We recently added a managed-storage option to the S3 export system in Flexprice. Originally, S3 exports required the usual setup: your own bucket, IAM policy, access keys, region config, and ongoing credential management.
