Ageinx is a hosted Authentication-as-a-Service platform. Redirect your users to us, we handle login and signup, then send them back to your app with a token. No auth code to write. Ever.
Redirect users to Ageinx. We handle authentication, hashing, tokens, and rate limiting. You receive a clean JWT identity response.
Ageinx gives your app a fully hosted login and signup page — with rate limiting, secure tokens, and user management built in. One redirect. One token. Your users are authenticated.
Ageinx is an Authentication-as-a-Service platform. Instead of building login flows yourself, you redirect your users to ageinx.vercel.app/auth/{your-slug} — we show them a clean login/signup page, authenticate them securely, then redirect back to your app with a signed JWT token.
Your backend then calls GET /auth/userinfo with that token to verify the user and get their data as JSON. That's the entire integration.
It's production-ready from day one — built with security as a hard constraint, not a feature to add later.
// Step 1 — Redirect your user to Ageinx // Link or redirect button in your frontend: window.location.href = 'https://ageinx.vercel.app/auth/your-slug'; // Step 2 — User logs in on Ageinx hosted page // They get redirected back to your callback URL: // https://yourapp.com/callback#token=eyJhbGci... // Step 3 — Parse the token in your callback page const token = new URLSearchParams( window.location.hash.substring(1) ).get('token'); // Step 4 — Verify token on your backend const res = await fetch('https://ageinx.vercel.app/auth/userinfo', { headers: { 'Authorization': `Bearer ${token}` } }); const { user_id, email } = await res.json(); // → { user_id: "uuid", email: "[email protected]" }
No enterprise gatekeeping, no usage traps. Stop paying a tax on every new user you acquire. Pay for what you use.
Ageinx was built because I kept solving the same problems on every project. So I built the solution once, properly, and made it available to everyone.
Every new project started the same way — setting up authentication, writing rate limiters, configuring logging. Hours of work that added nothing to the product I was actually trying to build.
I decided to build those things once, with real attention to security and reliability, and ship them as Ageinx — a hosted auth platform so developers never have to build login flows again.
I built this alone. That means I move fast, care deeply about every line I ship, and actually respond when you reach out. There's no team to blame — just me.
