Flexprice▲240Hi 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. That works if you already have infra in place, but it adds a lot of overhead for teams that just want recurring exports for invoices, events, or credit reports. Now there are two options: - bring your own S3 bucket - use a Flexprice-managed S3…

Hey HN, I’am Koshima, co-founder of Flexprice (https://flexprice.io/). Flexprice is an open source monetization platform for AI & Agentic companies. You can build usage-based, credit-based, or hybrid pricing models with full control. Usage-based billing works on paper, but breaks fast in production: (1) High-volume data (e.g., 10k API calls/sec from AI inferences) breaks naive pipelines, dropping events and causing underbilling or customer complaints. (2) Backfilling missing events or retroactive discounts screws up invoices, forcing 3 AM log stitching to avoid revenue…

Flex [1] is a transpiler that converts a series of statements in natural language to either Python, Java or C++, and is trained using Rasa NLU [2], an open-source framework usually used for training chatbots and voice assistants. Flex is a project I made in college in 2018 along with two of my classmates, Gourav and Sanjay. The initial idea was to create a voice assistant you could speak to that wrote code for you, similar to GitHub's upcoming (and a lot more advanced) project "Hey, Github" [3].
