Recost shows you exactly what code is burning money before your API bill explodes. It maps cost to endpoints, flags waste like duplicate calls and bad loops, and simulates scale impact. With AST analysis and runtime tracking, you don’t just track spend, you control it before it gets out of hand.

Do you think about API cost while coding?
Curious how people actually think about this. When you’re writing code that hits APIs, are you thinking about cost at all? Or is it more like something you deal with later if it becomes an issue? Feels like a lot of cost problems come from small things like loops, retries, or polling that don’t seem like a big deal at the time. Do you ever catch that stuff early, or nah?

Hey Product Hunt! 👋 We’re the team behind Recost. We built this after watching teams unknowingly blow through API budgets. At a hackathon, a team shipped a feature making ~200 concurrent API requests. It worked perfectly… until their API key got revoked. No visibility. No warning. Just everything shutting off. Recost gives you a cost intelligence layer for your APIs, so you can see and control...
