Everything you need to protect your software

A complete authentication and licensing toolkit, so you can focus on building your product.

License keys

Generate, distribute and revoke keys with expiry, tiers and usage limits. Issue keys in bulk from the dashboard or API.

HWID locking

Bind licenses to a single machine fingerprint to stop sharing. Reset hardware IDs on demand for legitimate users.

User authentication

Full username & password auth for your end users, with secure hashing and per-app isolation built in.

Live sessions

Track active sessions and heartbeats in real time. See exactly who is online across every application.

Bans & blacklist

Instantly ban users, keys, HWIDs or IP addresses. Cut off abuse without shipping a new build.

Simple REST API

One endpoint, predictable JSON responses. Integrate from any language in a handful of lines.

Built for developers

Integrate in minutes, not weeks

A single JSON endpoint powers initialization, registration, login and license checks. No SDKs required — just standard HTTP from any platform, desktop or web.

Owner ID + app secret authentication
Predictable success / message JSON responses
Works with C#, C++, Python, JS, and more

auth.js

// Authenticate a license key from your app
const res = await fetch("https://api.vahalla.dev/v1", {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({
    type: "license",
    ownerid: "YOUR_OWNER_ID",
    secret: "APP_SECRET",
    key: "VHL-XXXXX-XXXXX-XXXXX-XXXXX",
    hwid: getHardwareId(),
  }),
});

const data = await res.json();
if (data.success) {
  // valid license — unlock the app
  console.log("Expires:", data.info.expiry);
} else {
  console.log("Denied:", data.message);
}
