Comparison
Licensr vs. the alternatives
All of them can check a license key. The difference is everything around it: who owns the payment, what happens after the sale, and how much you build yourself.
Licensr vs. LicenseSeat
Both validate license keys and charge a flat fee. Licensr is the checkout and the license server. LicenseSeat attaches a license server to a checkout you already run, and goes further on SDKs, offline files, and update distribution.
Full-stack licensing platform
Best when you do not already have a store. Payment processing, a hosted buy page, subscription state, and license enforcement ship as one product.
- Checkout on your Stripe, Mercado Pago, PayPal, or Razorpay account
- Hosted buy page, 0% revenue share
- Renewal, grace, and cancellation tied to the license
- Domain-mode + Origin guard
- Official JS/TS, C++, C#, and Go SDKs with offline JWT verify on JS, C#, and Go
- Isolated organizations with roles
SDK-first licensing API
Best when you already sell on Stripe Payment Links, Gumroad, Paddle, Lemon Squeezy, Shopify, or Polar and want native SDKs, a license portal, and optional update hosting.
- Swift, Rust, C#, C++, and JavaScript, including Unity, Unreal, Godot, and Tauri
- Floating seats, metered licenses, and version-ceiling entitlements
- Customer portal and automatic key issuance from your processor
- Usage telemetry, plus installer hosting on Starter and up
Payment processing included
Licensr charges the buyer on your Stripe, Mercado Pago, PayPal, or Razorpay account. LicenseSeat does not take payment. It issues a key when Stripe Payment Links, Gumroad, Paddle, Lemon Squeezy, Shopify, or Polar reports a sale.
Revenue share
Both charge a flat platform fee and take no cut of sales. On LicenseSeat you still pay the store that takes the sale (Stripe, Gumroad, Paddle, Lemon Squeezy, Shopify, or Polar).
Hosted buy page (branded storefront)
Licensr generates /buy/your-slug. LicenseSeat leaves checkout on the store you already use.
Subscription lifecycle (renewal, grace, cancellation)
Licensr moves the license through renewal, a grace window, and cancellation. LicenseSeat extends expiry on renewal and can revoke on refund. A cancellation or failed payment does not revoke; access ends when the stored expiry passes.
Customer self-serve portal
Both ship a branded portal. Licensr adds seat management and the Stripe billing portal. LicenseSeat covers key recovery, device transfer, extra seats, and renewal, and can sit on your own domain.
License emails
Licensr has a visual editor for receipts, key delivery, renewals, and expiry warnings. LicenseSeat sends branded key emails on Indie and up. A white-label template editor is still on their roadmap.
License key validation API
Seat / node-locked activation
Domain-mode activation
Bind licenses to a domain instead of a machine. Essential for WordPress, browser, and SaaS plugins.
Domain-origin guard (anti-extraction)
Even if someone extracts your API key + license key, they cannot use it on an unauthorized domain.
Floating / concurrent licenses
LicenseSeat supports heartbeat-based check-in/check-out. We use node-locked seats.
Trial licenses (automated end-customer trial)
LicenseSeat has a first-class trial flow. We support time-limited keys via expiry dates, but there's no self-serve trial button on the buy page yet.
Feature-based entitlements
Licensr returns an arbitrary feature_flags object on every validate, activate, and token call. LicenseSeat entitlements are named, can expire on their own clock, and an updates entitlement can carry a version ceiling for paid major upgrades.
Metered usage licenses
LicenseSeat includes metered licenses. Licensr does not.
Offline activation
Licensr issues a short-lived EdDSA JWT you verify locally against a per-plugin JWKS. LicenseSeat checks out an Ed25519-signed, AES-256-GCM machine file bound to the device fingerprint, with clock-tamper checks. They also document air-gapped activation.
REST API
Native SDKs
Official SDKs for JavaScript/TypeScript (npm), C++ (CMake git), C# (NuGet + Unity UPM), and Go (go get). JS, C#, and Go verify offline JWTs locally; C++ mints and stores the token today. LicenseSeat also ships Swift, Rust, and a Tauri plugin, with Unity, Unreal, Godot, and JUCE integrations. Their SDKs retry, re-validate in the background, and send a heartbeat.

Public developer docs
Webhook events + replay
Licensr logs inbound payment webhooks and can replay them. LicenseSeat logs sales-connection events and can retry a missed issue, renewal, or refund.
Software distribution and auto-update
LicenseSeat hosts installers and serves an update feed with diff patches on Starter and up. Licensr does not distribute binaries.
Multi-tenant (multiple independent teams)
Each Licensr organization has its own products, licenses, users, and payment account. LicenseSeat has organizations. Team and organization licenses are still on their roadmap.
Roles & permissions (admin / member)
Licensr has admin and viewer roles on Studio and up. LicenseSeat distinguishes organization owner and admin.
Setup wizard / guided onboarding
Usage analytics (MAU, DAU, geo)
LicenseSeat's SDK reports MAU, DAU, geography, and app version automatically. Licensr tracks last-seen, activation counts, and revenue (MRR, churn, payments net of refunds).
Public pricing page
LicenseSeat lists Hobby (free, 100 devices), Indie ($9/mo billed yearly, 500 devices), and Starter ($29/mo billed yearly, 1,500 devices). Their comparison articles also list Pro at $79/mo for 5,000 devices. Licensr is Free, Indie $8.99, Studio $25.99, and Agency $75.99. We count active licenses; they count active devices.
Free tier
Both are free without a credit card. LicenseSeat Hobby includes 100 active devices. Licensr Free includes 25 active licenses and the hosted storefront.
Payments, storefront, and licensing, all in one.
Free tier, no credit card required. From signup to a live buy page in 15 minutes.
