Referral infrastructure for SaaS and app teams
GrowthRail is a developer-first referral platform for SaaS that helps teams launch and manage native referral programs in web and mobile apps. The product combines SDKs, a dashboard, attribution, webhooks, and analytics so referral flows can be added without building the entire system from scratch.
The site positions GrowthRail around practical implementation: teams can track referrals across JavaScript, React, React Native, Swift, and Kotlin; use hosted UI components for sharing; and connect identity, billing, and subscription systems through built-in integrations and a REST API. The pricing page shows a free Developer plan and a paid Business plan, with the hosted dashboard and API managed by GrowthRail.
Core capabilities
Web and mobile attribution
Track users from first web visit through mobile app install, with referral codes and device matching used to reduce attribution loss when deep-link payloads are unavailable.
Drop-in referral UI
Embed modal, drawer, inline panel, floating trigger, and new-user banner referral surfaces, all themeable from the dashboard.
Reward automation
Automatic reward fulfillment sends credits, discounts, upgrades, or other configured rewards when a referral converts, using webhooks with retries and delivery logs.
Fraud controls
Built-in safeguards help prevent self-referrals and abuse with project-level allow and block lists, single-claim enforcement, and auditable logs.
Analytics and segmentation
Monitor conversion rates, top referrers, and ROI from the dashboard, and use custom attributes to segment users and campaigns.
Common workflows
Launch a SaaS referral program
Add a referral program to a SaaS product and connect it to your conversion event, such as a paid subscription or purchase, without building custom referral plumbing from the ground up.
Unify web and mobile attribution
Track referrals across a web app and a mobile app so invites can follow users from first visit through install and later conversion.
Capture mobile app installs
Use referral codes, device matching, and themed share surfaces to support consumer apps where app-store installs can interrupt standard tracking.
Automate reward fulfillment
Automatically issue credits, discounts, upgrades, or payouts after a conversion event, with retryable webhooks and delivery logs for operational visibility.
Operate referral programs for a team
Manage campaigns, webhook endpoints, API keys, and analytics from a shared dashboard while keeping projects scoped and isolated for a team.
