Hey Product Hunt 👋 I’m thrilled to finally share APIStack with you all — a platform built out of a developer’s frustration with fragmented API testing, inconsistent billing, and complex integrations. With APIStack, our mission is simple: → Make APIs as accessible, discoverable, and usable as apps. 💡 What makes APIStack different: ⚙️ Unified API Marketplace – Explore, test, and subscribe to premium APIs in one place. 🧩 Instant In-Browser Testing – No setup. No Postman. Just click & test. 💳 Credit-Based Usage Billing – Pay only for what you use — no heavy subscriptions. 🧠 MCP Servers – Deploy and orchestrate multi-agent AI systems through our hosted MCP servers. 🔐 Secure Key Management – Your integrations stay safe while you scale. This is just the beginning. 🚀 👉 Check it out here: https://apistack.online I’d love your feedback, ideas, or even your wish-list APIs you’d like to see next! Thanks for supporting this journey ❤️

This is a fantastic idea. Are you managing the APIs yourself, or do the developers get to manage their own?
