One engine for every incentive you'll ever offer

Because charging a cut of your payouts is a success tax: the better your program does, the more you're penalized. Most affiliate tools meter you by tracked revenue, by payee, or by program. Siren is composition-based: one account runs many program shapes at once, and every one of those meters would punish exactly the thing we tell you to do freely. So you pay for what the engine can do. How much money flows through it is your business.

Collaborators and programs, on every tier. Pay one partner or ten thousand. Run one program or twenty overlapping ones. The price doesn't move. What separates the tiers is capability: teams, real-money payouts, hierarchies. Partner and program counts have nothing to do with it.

One thing: engine activity, meaning engagements and metrics, counted together as a monthly allowance (5,000 on Essentials, 50,000 on Plus, 500,000 on Pro). An engagement is a reward credit, created when a tracked touchpoint ties a collaborator to a sale. One sale crediting one partner in one program is one engagement, the same sale qualifying in two programs is two, and the engine marks each complete so nothing double-counts. A metric is a computation the engine runs to keep standings and totals current. They're the actual work Siren does on your behalf, so the allowance scales with genuine complexity and traffic. A single simple program barely touches it, while a busy multi-program account uses more. Your revenue, your partner count, and your program count never enter the math. Nobody gets penalized for a good month.

Nothing shuts off, and we never bump you to a higher tier automatically. Extra activity bills at a small flat fee per engagement for that month, and your allowance resets at the start of each billing cycle. Your founding discount applies to your plan price, not to overage fees. Well before you get close, we'll reach out with your usage, your reset date, and the math on whether overage or an upgrade is cheaper for you. The decision is always yours.

Same engine. But Cloud isn't just the WordPress plugin with hosting bolted on. There's nothing to install, update, or keep online, and Cloud reaches beyond the WordPress ecosystem: webhooks and a REST API let you trigger rewards from any third-party system (Shopify, Stripe, custom apps) and attribute conversions across multiple channels at once. The WordPress edition generally stays inside WordPress and is licensed yearly per site. Self-Serve is a monthly or annual subscription with Essentials, Plus, and Pro tiers.

Most multi-program operators belong on Plus. It's built for running several reward structures at once. Essentials is the lighter starting point if you're running a single straightforward program. Pro is for high-volume operations: the same capabilities as Plus with hierarchies and cascading rewards on top, and far more monthly engine-activity headroom. Your 30-day trial runs on Pro, so you can try everything before you pick.

Yes, and the move is on us. We carry your full history across, and nothing gets left behind on the old site.

Yes. Sign up and you get 30 days of full Pro access, with no card. There's no free-forever plan on Cloud. When your trial ends you pick the tier that fits. Buy among the first 20 accounts and 50% off stays with you for life.

Buy a plan while founding spots remain. The first 20 accounts to buy get 50% off, applied at checkout. You can buy straight away, or start the free trial and buy before it ends, but a trial doesn't hold a spot. The rate stays yours for as long as your subscription stays active. Cancel and it lapses.

Yes. These are the prices checkout charges. Founding members pay half the plan price for life.
