In their own words
Siren
Siren manages partner and incentive programs for affiliates, referrals, royalties, loyalty, revenue sharing, and sales commissions. It tracks clicks, leads, sales, renewals, and other events, then attributes outcomes and calculates commissions or rewards. Its feature page describes five attribution models: first-touch, last-touch, top-score, shared engagement pool, and performance-weighted pool. A partner portal supports partner access, while Siren tracks approvals and payouts and exports payout batches for the payment method a customer uses. WordPress integrations include WooCommerce, Easy Digital Downloads, LifterLMS, LearnDash, Gravity Forms, Ninja Forms, and North Commerce. Managed Cloud integrations include Shopify, Stripe, HubSpot, Salesforce, NetSuite, plus API and webhook connections. Siren is available as a self-hosted WordPress plugin and in hosted Cloud or Full-Service editions. For WordPress, affiliate, commission, and payout records remain in the customer's WordPress database and can be exported. The Lite plan is free. Paid WordPress plans start at $229 a year for Essentials; Plus is $299 a year and Pro is $499 a year. The plugin requires self-hosted WordPress 6+ and PHP 8.1 or newer, and does not directly integrate with MemberPress.
