Hey Product Hunt 👋 I’m Calvin, the maker of Best API. I built this because I kept seeing the same pattern with smaller AI products: a lot of teams don’t actually want a full multi-model platform, routing layer, or enterprise AI stack. They already know the OpenAI API workflow. What they want is something much simpler: * lower API cost * minimal migration * a familiar developer workflow * less code to change So Best API is intentionally narrow in v1: * OpenAI-compatible * focused on minimal migration * built for indie developers, early AI startups, and content-heavy / low-sensitivity apps What it is not: * not a multi-model gateway * not an enterprise governance/security platform * not built for highly regulated workloads If you already use the OpenAI format, the goal is to make switching feel straightforward while improving unit economics. I’d especially love feedback on: 1. whether the positioning is clear 2. whether the migration story feels credible 3. what would stop you from trying a third-party OpenAI-compatible layer Thanks for checking it out — happy to answer any questions here today.
