Why store and course owners run Siren

No per-affiliate fees, no bloated bolt-ons, and no ceiling on what your program can become.

Native to the plugins you already run

Siren hooks straight into WooCommerce, Easy Digital Downloads, LifterLMS, LearnDash, Gravity Forms, and NorthCommerce. A sale or a course completion fires the reward on its own. No middleware, no scripts pasted from some third-party dashboard.

Unlimited affiliates, one flat price

Most affiliate tools charge more as you recruit, or skim a cut of what you pay out. Siren never does either. Your hundredth affiliate costs exactly what your first one did: nothing.

Grows past where affiliate plugins stop

One affiliate program is just the start. The same plugin grows into recurring commissions on subscriptions, course completion rewards, creator royalties, and partner teams with hierarchies of their own. You upgrade a tier instead of migrating to new software.

Your program lives in your database

Every affiliate, commission, and payout record sits in your own WordPress database. If we vanished tomorrow, your program history wouldn't. Anyone who's watched a plugin get abandoned knows why that matters.

Reviews

Loved by program builders

What people running real programs say about Siren, including the CEO of LifterLMS.

Questions, answered

What's the difference between the WordPress edition and Cloud?

One engine, two ways to run it. The WordPress edition is the plugin on this page. Install it on your site, where it hooks directly into WooCommerce, your LMS, and the rest of your stack, licensed yearly per site with a free tier to start on. Cloud is the hosted version we run for you, built for programs that reach beyond a single WordPress site.

Is there a free version?

Yes. Siren Lite is free. Create a free account and download it right here, no credit card required. It's a genuinely capable affiliate plugin: run unlimited programs, track referrals via links or manual credit, pay flat or percentage commissions, and record payouts by hand. Upgrade to Essentials, Plus, or Pro when you outgrow it.

How do the four WordPress tiers build on each other?

Each tier is a strict superset of the one below. Lite runs unlimited affiliate programs with link and manual tracking. Essentials adds Program Groups (so overlapping programs don't pay out twice on the same sale) plus coupon code tracking, more reward models, integrations, and a Collaborator Portal. Plus is where affiliates become teams: Collaborator Groups, priority support, and early access to new features as they ship. Pro adds partner hierarchies and cascading commissions for partners who recruit and lead teams of their own.

How does licensing work across sites?

Paid WordPress licenses are billed annually and cover a single WordPress site. Running Siren across many client sites? That's what the agency program is for: bulk licensing through our agency channel.

Will Siren slow down my site or fight my caching plugin?

No. Siren was designed for performance from the start, and tracking, attribution, and commission calculations run efficiently even on high-traffic stores. Tracking is first-party and runs against your own database, so it works alongside standard caching setups instead of depending on fragile page-level workarounds.

Does Siren support WooCommerce Subscriptions?

Yes. You can configure programs to pay commissions on the initial purchase, on renewals, or both.

Do I get plugin updates and support?

Yes. Every plan includes automatic updates for as long as your license is active. Open a support ticket and we'll get back to you. Paid plans include email support, and Plus and Pro subscribers get priority response times.

What if I need something Siren doesn't do out of the box?

Start with Beacon, our free AI assistant. Describe what you want in plain English and Beacon searches the documentation, finds the right configuration, and generates a recipe you can install in one click. For truly custom logic, Siren has a full extension API developers can build on.

Does Siren work with AI-agent commerce (ChatGPT, Google UCP, agentic checkout)?

Yes, because Siren's attribution model was never click-only. An opportunity fires on any attributable event: a click, a coupon, a bound post visit, a partner-specific product sale. When a customer buys through an AI assistant without ever visiting your site, the conversion can still attribute correctly through the artifact they consumed earlier, like a post they read or a product variant bound to the partner. Our guide to affiliate attribution in the age of AI agents has the full picture.

Can I upgrade tiers later?

Anytime. Tiers are additive, so every program, collaborator, and payout you've configured carries straight over when you move up. Nothing to rebuild.

The Siren thesis

Pay your first affiliate before you ever pay us.

Siren Lite is free forever, with unlimited programs and unlimited affiliates on the store or course site you already run. Install it tonight, hand a few good partners their links, and record a real commission. The paid tiers, with coupon tracking, the affiliate portal, and partner teams, can wait until the program earns them.
