Software licensing,
finally done right.
Drop-in authentication and license management for modern software. Built on a global edge network with encryption-first defaults — so you can ship secure products without writing your own backend.
A complete platform for
software protection.
Every feature you need to license, distribute, and monitor your software — in one cohesive platform built for production.
Encryption-first
AES-256-GCM at rest. Per-request signed payloads. Anti-tamper, anti-debug, HWID binding — built in.
Global edge network
36 regions worldwide. Auth completes in under 10ms from any major city.
12+ first-party SDKs
C++, C#, Python, Rust, Go, Node, Java. Drop-in client libraries with full IntelliSense.
Encrypted variables
Store configs and secrets in our zero-knowledge vault. Pull at runtime, never embed in binary.
Webhook automation
Trigger Discord, Slack, or any URL on auth events. Build workflows without writing infrastructure.
Real-time analytics
Live dashboards, geo heatmaps, fraud detection. Know who is using your software, in real time.
Authentication in
single-digit milliseconds.
Our edge network spans 36 regions across 6 continents. Every auth request hits the nearest node, validates against our distributed database, and returns a cryptographically signed response — typically in under 10ms.
Integrate in minutes,
not days.
A clean REST API and first-party SDKs in every language you use. Add license validation, HWID binding, and feature gating with a few lines of code.
- Idempotent REST API with full OpenAPI spec
- Official SDKs for 12+ languages
- Webhooks with HMAC signature verification
- Real-time WebSocket events
- Detailed logs and replay tools
// Initialize once at app startup
using FreeAuth;
var auth = new AuthClient({
name: "MyApp",
ownerId: "7Fa2..b91c",
secret: Env("FA_SECRET"),
version: "1.0.0"
});
// Verify license on startup
var result = await auth.VerifyAsync(licenseKey);
if (result.Success){
App.Run(); // ✓ protected
} else {
App.Exit();
}
Simple pricing.
Built to scale.
Start free. Upgrade when you grow. No surprise bills, no per-seat tax.
"Replaced our entire in-house licensing service in a single afternoon. The webhook system alone saved us months of work."
"The latency is genuinely absurd. Our auth went from 200ms on a custom service to 6ms on FreeAuth. Users noticed."
"Encryption-by-default and a clean SDK API meant we passed our SOC 2 audit on the first try. Recommended."
