Siren review
A strong WordPress-focused option for flexible attribution and recurring partner commissions.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Siren is affiliate and partner program software for stores, course creators, SaaS companies, marketplaces, and other organizations that reward partner-generated activity. Its WordPress edition runs on the site owner's infrastructure and connects with ecommerce, learning management, and form plugins. The product covers referral links, coupon codes, leads, sales, renewals, commissions, approvals, and payouts, with web, API, and self-hosted options.
Pricing is structured around four WordPress plans billed annually per site. Siren Lite is free and includes unlimited programs, affiliates, and conversions, basic ecommerce integrations, multiple commission-rate types, referral and coupon tracking, and CSV payout exports. Essentials costs $229 per site per year and adds recurring subscription commissions, program groups, advanced attribution, an affiliate portal, and store-credit payouts. Plus costs $299 and adds collaborator groups, Stripe Connect real-money payouts, lifetime commissions, and priority support. Pro costs $499 and adds partner hierarchies, reporting-line overrides, and cascading commissions up to five layers.
Attribution is Siren's clearest differentiator. Teams can use first-touch, last-touch, and multi-touch models, while commission rules can cover sales, leads, renewals, and products. Partner portals expose earnings and referral links, and the REST API and event ingestion support broader implementations across tools such as WooCommerce, Shopify, Stripe, HubSpot, and Salesforce. Siren fits organizations that need flexible partner structures and WordPress deployment. Teams seeking a simple referral tracker may find its hierarchy and cascading-commission features unnecessary, while payout operations should account for the fact that Siren records and exports payout data but does not move funds on every edition.
