Licensing & anti-piracy for developers, designers, and agencies

Issue keys, verify installations, and enforce usage — without killing UX.

DevPayr helps creatives get paid and stay protected:

  • License issuance (per-domain, time-bound)
  • Verification (online heartbeat + offline grace)
  • Enforcement (limits, revocation, throttles)
  • Anti-piracy (fingerprints, tamper checks, plugin forr designers)

Built for real-world distribution

From plugins to SaaS seats to desktop apps

Unlike generic payment links or manual key files, DevPayr is a licensing brain that fits your product:

  • Plugins/Themes/Templates — WordPress, Figma/Photoshop extensions, Laravel/Nova add-ons.
  • Desktop & Mobile Apps — device fingerprints, offline tokens, and tamper checks.
  • SaaS/Server Software — per-domain licensing, domain binding, org quota & revocation.
  • Agencies — license client deliverables cleanly with transfer/assignment.

Modules & capabilities

Everything around licensing — not just keys

  • Issuance — keys, signed tokens (JWT/JWE), entitlements, and claims.
  • Verification — online (fast path) with HMAC signatures; offline token refresh with grace windows.
  • Domain Bindings — browser+OS fingerprint, MAC hints (where permitted), domain & origin checks.
  • Enforcement — per-license install limits, per-org seat caps, kill-switch & staged revocation.
  • Telemetry (opt-in) — activation counts, suspicious usage.
  • Compliance — audit logs, evidence packs for disputes, data minimization by default.
  • Distribution hooks — Composer/NPM/PyPI/Github Releases gating; signed download URLs.

Typical workflows

Enforce licensing without breaking UX

  1. Create account → Project: sign up on DevPayr and create a project for your app/plugin/theme.
  2. Define license model: choose per-domain, or time-bound trial; set limits, expiry, and offline grace.
  3. Issue keys: generate licenses (single, bulk, or via API). Optionally bind to domain/device/org and add custom claims/entitlements.
  4. Integrate & verify: add the DevPayr SDK to your app; client sends key + fingerprint → receives signed OK with entitlements (offline grace supported).
  5. Enforce & manage: enforce install caps/seat counts/domain binding; revoke or throttle when abused; view telemetry & audit logs.

Use cases

Where DevPayr shines

  • WordPress/Laravel plugins & themes — per-domain or per-site keys with updates gated.
  • Figma/Photoshop/Sketch extensions — per-seat licensing with org transfer & revocation.
  • Desktop utilities (Electron, .NET, Swift) — per-device keys with offline grace & tamper checks.
  • SaaS seats & on-prem tools — org plans with seat counts, domain binding, and SSO friendly.
  • Agencies — deliver licensed software to clients with assignment, expiry, and support tiers.

Benefits

Protect revenue, reduce abuse, keep UX smooth

  • Get paid reliably — stop unpaid usage and serial key sharing.
  • Cut support load — clean revocation, clear states, fewer manual checks.
  • Go global — Paystack/Flutterwave/Stripe/PayPal/Nomba supported; regional rules possible.
  • Fewer moving parts — licensing, verification, enforcement, webhooks in one system.
  • Security by default — signed requests/responses, rotating secrets, minimized PII.

Why not just payment links or manual keys?

DevPayr vs DIY & generic tools

  • DIY often lacks revocation, org seats, and robust anti-piracy.
  • Generic license widgets don’t model device/domain/seat limits well or support regional gateways.
  • Manual keys create support debt and are easy to leak; no telemetry or enforcement.

FAQs

What license models are supported?
Per-doman, Per-project(One-time & Unlimted) are supported
How does offline usage work?
DevPayr works offline if you are using one of our SDKs We cache every request ensuring that the software works offline, and you can control this from your code or plugin
Can I revoke a license after a refund or chargeback?
Yes. if using the API, you can lock a project, or from the UI
How do you prevent key sharing?
Bind licenses to domains/license. Enforce install caps and flag anomalies for follow-up.
Is there a kill-switch?
Yes. You can revoke instantly; SDKs surface block/grace states without crashing the app.
What about privacy & PII?
We minimize PII and use hashed fingerprints. Requests are signed; sensitive data is never required.
Do you support package managers?
Yes — Composer, NPM, PyPI, and gated release downloads.
Which gateways are supported?
We do not dictate for you how to receieve your payment
Can agencies license deliverables for clients?
Yes. Issue licenses per client, assign domains or limit number of domains, and transfer ownership later.
Do you have SDKs?
First-party SDKs for PHP, Node, and Python with HMAC-signed requests and idempotency.
Do you offer on-prem?
At the moment, we do not offer on-prem
