In their own words
OpenPartner
OpenPartner is a partner attribution platform for tracking clicks, identity, revenue, and payouts. It is positioned for SaaS, ecommerce, and other businesses running partner programs, as well as creators promoting brands. Brands can optionally list offerings on the OpenPartner Network, where creators can browse programs and apply. Brands pay partners directly through Stripe Connect; OpenPartner does not hold money. Listed integrations include Stripe Billing webhooks and CRM workflows for HubSpot, Salesforce, Pipedrive, Close, and Copper, as well as Zapier and Make. The browser SDK is installed as @openpartner/sdk and ships ESM and CJS bundles with no runtime dependencies. Self-hosting uses Docker Compose for Postgres, the API, click router, and portal on one machine, and requires Docker 24+ with 2GB RAM minimum. Hosted data residency is in the US today; SOC 2 Type II is planned, and DPA support is available on request. Hosted Revshare is priced at 3% of GMV with no monthly fee; Flex is $49 per month plus 1.5% of GMV. A free self-hosted core is listed.
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.
