Get paid for your AI app — in 10 minutes.
PayKit drops credits, usage metering & subscriptions into any AI app (Lovable, Bolt, v0, Cursor, Next.js). Charge per generation, sell credit packs, and never lose money on model costs. No backend required.
Built by an AI engineer who got tired of re-wiring Stripe for every LLM app.
Sound familiar?
- – You built an AI app — now you're bleeding money on OpenAI/Anthropic bills with no way to charge users.
- – Stripe + usage metering + a billing portal = days of backend plumbing you didn't sign up for.
- – Generic billing tools don't understand per-token cost — so your pricing quietly eats your margin.
Credits & usage billing, built for AI
Meter every AI call in one line. Sell credit packs, top-ups, and pay-as-you-go — with model costs tracked so your price always beats your bill.
Subscriptions & paywall in 3 lines
Stripe Checkout, plans, a customer portal, and hasAccess() gating — you never touch a webhook.
Drop-in, no backend
Paste an API key into your Lovable / Bolt / v0 app. A React <Paywall> and usePayKit() hook. Live in minutes.
The 10-min promise
import { paykit, Paywall, usePayKit } from "paykit"
await paykit.meter("image_gen") // deduct credits, block if empty
<Paywall plan="pro"><ProFeature /></Paywall> // gate a feature
const { hasAccess, credits } = usePayKit() // check access anywhereFree while you test. $19/mo when you launch. No revenue cut on the starter plan.
Stop wiring Stripe. Start charging.
I'm building this in public — tell me what your AI app needs and I'll build it first.
