API Design head-to-head

Keymint SDKs focus on readable, modern syntax. Compare key validation methods side-by-side.

Keymint Implementation

// Keymint SDK Verification
import { KeyMint } from 'keymint';

const client = new KeyMint('YOUR_CLIENT_API_KEY');
const result = await client.activateKey({
  productId: 'PRODUCT_ID',
  licenseKey: 'LICENSE_KEY',
  hostId: 'DEVICE_FINGERPRINT'
});

Zentitle Implementation

// Zentitle (Nalpeiron) – entitlement check via REST
const res = await fetch("https://api.nalpeiron.com/entitlement/check", {
  method: "POST",
  headers: { "Content-Type": "application/json", Authorization: "Bearer ZENTITLE_TOKEN" },
  body: JSON.stringify({ productId: "PRODUCT_ID", feature: "PRO_FEATURE", userId: "USER_ID" })
});
const { entitled } = await res.json();

Offline Verification

Supporting air-gapped networks is a major requirement for desktop software. Compare our offline signing models:

Keymint Offline (.lic JWTs)Generates Ed25519-signed JWT license files (.lic) verified locally using public keys, with no server to host.

Zentitle Offline ModelSupports offline-first SDK cache plus Docker Local License Server for dark sites and air-gapped deployments.

SDK Support

Official SDK wrappers keep integration times short and clean. Verify language coverage:

Keymint SDK EcosystemModern, lightweight SDKs for Node.js, Go, Python, and C#/.NET, designed for Electron, Tauri, SaaS, and cross-platform desktop.

Zentitle Integration SDKsSDKs for .NET, Java, Python, C++, Node plus REST; offline-first cache built into the SDK.

Frequently Asked Questions

Common questions from developers comparing Keymint with Zentitle.

How much does Zentitle cost vs Keymint?

Zentitle public pricing starts at $600/month (Starter) with Growth $1,200 and Scale $2,400, no free tier, and 24-month minimums on SMB plans. Keymint starts at $29/month. For a 1-product team, Keymint saves roughly $570/month before Enterprise negotiation.

Does Keymint support offline and floating like Zentitle?

Yes for file-based offline (signed Ed25519 JWT .lic verified locally) and floating seats (checkout/heartbeat/checkin). Zentitle uses an SDK cache plus a Docker Local License Server you host; Keymint needs no server.

When should I stay on Zentitle?

Stay if you need AI-token usage metering, feature-flag entitlements decoupled from code, reseller portals, SSO/audit/single-tenant, or revenue analytics tied to Salesforce/NetSuite. Keymint does not target those enterprise monetization flows.

Can I migrate off Zentitle without downtime?

Yes. Run both in parallel: issue Keymint-native keys while Zentitle entitlements stay live, then sunset Zentitle after your base upgrades. Customer records and metadata carry over.

Final Recommendation

Zentitle wins large enterprise deals on track record (patents, Sony/UiPath references), monetization depth (usage/AI metering, Salesforce/NetSuite revenue ops), and regulated-buyer checkboxes: SSO, audit logging, reseller portal, EU/US data sovereignty, and Local License Server for air-gapped sites.

Keymint gives indie and mid-market teams node-locking, floating seats, and offline verification without the $600 entry, ARR gates, rev-share, or 24-month lock-in. If you don't need AI-metering or single-tenant procurement, Keymint gets you licensed in an afternoon for roughly 5% of the cost.
