Rapidly ship SaaS integrations
without ever leaving your terminal.
IntegrateAPI installs production-ready Stripe, Clerk, Supabase, OpenAI and dozens more directly into your Next.js project — one CLI command, real TypeScript, zero runtime SDK lock-in.
$ npx integrateapi add stripecopy & run — that's it.Supported integrations from the best in the industry.
Auth, billing, data, AI, observability, comms — wired up the way modern teams actually ship them.
Built for the modern API.
Three ways to work with IntegrateAPI. Templates to install production code, Stress Test to find scaling risks, Registry to learn how the modern stack actually fits together.
Install integrations instantly
Production-ready TypeScript dropped into your /lib folder. No SDK lock-in, no runtime layer.
Find scaling risks before incidents
Score your SaaS architecture across auth, billing, data and observability — with actionable fixes.
Explore real API patterns
Browse webhook flows, idempotency, retries and rate-limit recipes. Real implementations, not toy code.
Typed end-to-end, by default
Every integration ships with strict, modern TypeScript. Types for events, payloads, errors — out of the box.
It's your code, not a black box
No hidden SDK wrapping your API calls. Read it, edit it, extend it, ship it. You keep the source forever.
From zero to shipped in <30s
Install, generate, wire webhooks and types in a single command. The CLI does the boring parts.
Ship faster. Own the code.
IntegrateAPI doesn't add a layer between you and the API. When you run npx integrateapi add stripe, working code lands in /lib/integrations. That's where it stays — versioned with your repo, reviewed by your team, deployed with your app.
import Stripe from "stripe";
// TODO: idempotency? retries?
// TODO: signature verification?
const stripe = new Stripe(process.env.STRIPE_KEY!);
export async function POST(req: Request) {
const body = await req.text();
const sig = req.headers.get("stripe-signature");
// 60+ lines of error-prone handler...
}import { verifyWebhook } from "@/lib/integrations/stripe"; export async function POST(req: Request) { const event = await verifyWebhook(req); return handle(event); }
Code lives in your repo.
Real TypeScript, in /lib/integrations, versioned with your project. No magic, no proxy, no upgrade dread.
