Show HN: ServerlessAI – Build, scale, and monetize AI apps without back end

Hello HN, I’ve always loved building frontend-only apps—those you can prototype over a weekend, host for free on GitHub Pages, and scale to millions of users. Unfortunately, AI-enabled apps complicate things, as exposing your OpenAI key to the world is obviously a no-go. This also means mobile developers often have to run their own servers. That’s why I built ServerlessAI, an API gateway that lets you securely call multiple AI providers directly from client side using OpenAI-compatible APIs. You can authenticate users through any identity provider, like Google or Apple, and set per-user request or spending quotas. You can also define an allowlist for endpoints and models. To monetize, you can apply different quotas for various user tiers. To start, I recommend checking out our tutorials, where we walk you through building a complete, deployment-ready AI app in 5 minutes. We’ve got tutorials for React, Next.js, and iOS: https://serverlessai.dev/docs/tutorials/ O
