For developers who sell software and want licensing, payments and update delivery on their own infrastructure, with no per-license fees. It is the license and update server behind TigerTradeBot and TigerPassword.
Verify a license offline
Your app pins the public key at build time and checks the license file’s RSA-4096 signature locally. This example is from the Go SDK’s README. The SDKs for Rust, Java, Spring Boot, .NET and .NET Framework verify the same signed files.
v, err := tl.NewVerifierFromFile("tigercodes-public.pem")
if err != nil {
log.Fatal(err)
}
r := v.VerifyOfflineFile("license.offline.json")
if !r.Valid {
fmt.Println("license invalid:", r.Error)
return
}
if r.HasFeature("premium") {
// enable premium features
}What it does
RSA-4096 signatures checked against a public key pinned in your app. Licenses keep verifying even if TigerCodes disappears.
Machine fingerprints and concurrent-session limits, grace periods, and trials limited to one per email per product. Revoke, suspend, reinstate and transfer.
Hosted Checkout and an embeddable signup widget. Renewals re-sign the same license; a dispute revokes it. Customers manage billing in Stripe’s portal.
Stable, beta and trial channels, signed update manifests, one-time download links that expire after 72 hours, and a tigerpublish CLI.
Go, Rust, Java, Spring Boot, .NET and .NET Framework.
Two-factor sign-in required for admins (TOTP, FIDO2, passkeys), scoped HMAC-signed API keys, anomaly alerts, GDPR export and erasure, and white-label branding.
How it works
Deploy it with Docker Compose and generate your RSA-4096 key pair.
Create products. Sell through Stripe, or issue licenses from the admin, the CLI or a bulk import.
Your app verifies licenses with an SDK, offline or online, and pulls signed updates.
Under the hood
Pricing model
The planned model is a one-time purchase per company: unlimited licenses, no per-license fee.
An optional yearly maintenance plan would cover new major versions, with minor and patch releases included for every buyer.

No. The planned model is a one-time purchase, and you issue as many licenses as you need.
BadgerDB (the embedded default), PostgreSQL 14+ and MongoDB 8, with migration between them.
Go, Rust, Java, Spring Boot, .NET and .NET Framework.
