Hubble Subscriptions: An opensource subscription management platform

Hi, Hubble Subscriptions offered an easy-to-integrate subscription management service to startups and businesses, with a variety of customer acquisition and retention tools (or at least they were in our product road map). We participated in Y-Combinator Build Sprint in our second month. Ultimately we ceased operations as we did not find a USP. We made our source code opensource yesterday under Apache License v2. Hoping someone found it useful, either as a learning material or for their own business. We got an overwhelming response from the r/programming community on Reddit. Shortly after, we decided to see where we could take Hubble on its new journey. If you are aware of problems that Hubble Subscriptions aligns with, please let me know. I would still love to work on it.
