Use cases
GrowSurf gets product and marketing teams a refer-a-friend program live in days. It auto-generates a unique link for each user, embeds a white-labeled widget inside your app, and hooks into your CRM and billing stack without much engineering. That works when your referrers are already your users. But if your growth is creator-led, it's worth bearing in mind that GrowSurf has no way to find new creators.
This list covers nine alternatives across three groups: in-product SaaS referral tools, ecommerce refer-a-friend apps, and creator-led affiliate platforms built for Shopify. We picked them on tracking accuracy, pricing that scales without surprises, integration depth, and real user feedback. If you've been trying to bend GrowSurf into a shape it wasn't made for, one of these will fit better.

π₯ Best for: In-house marketing teams at ecommerce brands (especially Shopify) who need end-to-end influencer management, from discovery through payment.
π€ What is Modash?
Modash is an influencer marketing platform built for the full creator lifecycle. You find creators, vet them, run outreach, track their content and sales, and pay them globally, all in one place.
Where GrowSurf turns your existing users into referrers, Modash starts a step earlier. It finds new creators across 380M+ public profiles on Instagram, TikTok, and YouTube and invites them into your program.
It's aimed at Shopify D2C brands selling physical products with a person who owns the influencer program. If that's you, the Shopify integration ties creator activity straight to store revenue, so you're not exporting CSVs to prove ROI.
Key features:



Affiliate tracking: Sales attribute against real Shopify orders, where affiliate discount codes take priority over links, non-affiliate codes don't block link attribution, and link clicks stay valid 30 days on a last-touch basis. You set named commission tiers as a percentage of sales or a fixed amount per order. GrowSurf runs on product and CRM events wired through webhooks, so it isn't built for Shopify affiliate tracking in this order-and-code way.
Worth noting: Modash isn't a customer refer-a-friend engine. It doesn't embed a widget in your product or auto-generate a per-user link the way GrowSurf does. If your growth motion is existing users inviting friends inside a SaaS product, GrowSurf's model fits that better. Modash is for creator-affiliate programs, and its attribution runs through Shopify specifically.
Price: Starts at $299/month (annual). 14-day free trial β no credit card needed.

π₯ Best for: Ecommerce and DTC brands on Shopify or WooCommerce that need reliable affiliate sales tracking and automated payouts.
π€ What is Refersion?
Refersion is an affiliate and influencer platform focused on tracking referral sales and paying commissions. It's built for ecommerce, integrates with Shopify, WooCommerce, and Stripe, and includes a marketplace for recruiting affiliates.
Key features:
Worth noting: The Launch and Growth plans charge a percentage of affiliate-driven sales on top of the monthly fee, so cost climbs as affiliate volume grows.
Price: Free Marketplace listing; paid plans start at $29/mo + 3% of affiliate-driven sales (annual).

π₯ Best for: Shopify DTC brands launching and scaling affiliate, influencer, and referral programs natively inside their store.
π€ What is UpPromote?
UpPromote is a Shopify-native affiliate platform. It handles program setup, multiple tracking methods, automated commissions, and creator recruitment, all inside your store.
Key features:
Worth noting: Paid plans also add a 1 to 2% performance fee on referral sales on top of the monthly subscription.
Price: Free Essentials plan; paid plans start at $24.99/mo (billed annually) +2% successful referral sales.

π₯ Best for: Ecommerce brands, especially on Shopify, that want customer referral and affiliate programs to drive sales without more paid ad spend.
π€ What is ReferralCandy?
ReferralCandy is a customer acquisition platform for launching referral and affiliate campaigns quickly. It runs customer-led referral and creator-led affiliate programs side by side in one system, with branded pages and automated tracking.
Key features:
Worth noting: ReferralCandy focuses on customer referral rather than creator discovery, so there's limited tooling to find new influencers. The success fee runs up to 10.5% on the Basic plan, charged on referred customers' first three orders on top of the monthly base.
Price: From $39/month + 10.5% success fee.

π₯ Best for: SaaS startups, newsletter creators, and ecommerce brands wanting template-based referral, waitlist, or giveaway campaigns without code.
π€ What is Viral Loops?
Viral Loops is a referral platform built around ready-made templates modeled on well-known brand campaigns. It covers refer-a-friend, prelaunch waitlists, newsletter referrals, and invite-based giveaways across SaaS and ecommerce.
Key features:
Worth noting: Viral Loops has no creator discovery functionality, so it won't help you find new influencers to recruit.
Price: Plans start at $35/mo (annual billing, up to 1,000 participants). Free trial available.

π₯ Best for: Established businesses with high customer volume and existing word-of-mouth wanting a no-code customer referral program.
π€ What is Referral Factory?
Referral Factory is no-code referral software for building branded referral pages, tracking referred leads and conversions, and automating rewards. It serves customer referral programs across education, finance, professional services, home services, wellness, and SaaS, and connects to CRMs and payment tools.
Key features:
Worth noting: Paid plans start at $160/mo (billed annually).

π₯ Best for: SaaS companies using Stripe or Paddle who want to launch affiliate and referral programs quickly without engineering resources.
π€ What is Rewardful?
Rewardful is affiliate and referral software built tightly around Stripe and Paddle. It tracks referrals, commissions, and recurring revenue for subscription businesses, which is a close match to GrowSurf's SaaS home turf.
Key features:
Worth noting: Rewardful is built for SaaS subscription revenue, not Shopify order and discount-code attribution.
Price: 14-day free trial available. Paid plans from $49/month (or get two months free with annual billing).

π₯ Best for: Operators in service, ecommerce, and multi-location businesses who want a referral program set up and run with dedicated advisor support.
π€ What is Referral Rock?
Referral Rock is referral marketing software with a hands-off setup model. Its differentiator is advisor support, so a team helps you build and run the program rather than leaving you to self-serve.
Key features:
Worth noting: Referral Rock centers on customer referral, so it doesn't handle creator discovery for recruiting new influencers.
Price: Paid plans start at $250/month (or 10% off annual).

π₯ Best for: Ecommerce and subscription brands wanting referral, loyalty, and influencer programs on a single unified growth platform.
π€ What is Friendbuy?
Friendbuy is a growth platform that runs referral, loyalty, and influencer programs together in one system. It's aimed at ecommerce and subscription brands that want those motions under one roof.
Key features:
Worth noting: Friendbuy doesn't publish detailed pricing, so you'll need to contact them to evaluate cost against your program size.
Price: No public pricing; quote-based.
GrowSurf embeds a referral program in your product and gets marketing teams live in days without heavy engineering. For a SaaS or fintech team activating existing users, that model earns its place. The friction shows up in what sits behind a higher plan, and in what the model doesn't do.
Key capabilities are gated to the Business plan
Custom domain, Salesforce integration, PayPal integration, and realtime support all require the Business plan at $314/month or more. If you need any of those, the entry price isn't the real price.
The Startup tier caps programs and seats tightly
The lowest tier limits you to 2 referral programs and 2 team members. If you're running more than one program, or you have a few people who touch it, you outgrow that ceiling fast and move up a plan sooner than the sticker suggests.
Is GrowSurf better for SaaS or ecommerce?
SaaS, clearly. GrowSurf's strength is embedding a refer-a-friend widget inside a product and tracking referrals through product, CRM, and billing events. For an ecommerce brand tracking Shopify orders and discount codes, a Shopify-native tool like UpPromote, Refersion, or Modash fits the actual motion better.
Which alternative is best for a creator-led Shopify program?
Modash. GrowSurf activates existing users, so it has no way to find new creators. Modash searches 380M+ profiles across Instagram, TikTok, and YouTube, attributes sales against real Shopify orders, and pays creators globally as vendor of record. That's a different job than refer-a-friend.
Do these tools charge a performance fee on top of the subscription?
Some do. Refersion adds 3% (Launch) or 2% (Growth) of affiliate-driven sales, UpPromote adds 1 to 2% on paid plans, and ReferralCandy charges a success fee up to 10.5% on Basic. Modash and the flat-fee SaaS referral tools don't take a percentage of your referral revenue.
Does GrowSurf handle affiliate payouts and taxes?
GrowSurf files tax forms and holds payouts until tax info is complete, but you remain the payer of record. Modash takes the opposite approach as vendor of record, handling invoicing and international tax compliance across 180+ countries so the liability sits with them.
Can any of these find new influencers, not just activate existing users?
GrowSurf, Viral Loops, Referral Factory, and most referral tools work off people who are already your customers. Modash is the one that finds and vets new creators inside the same tool that tracks and pays them.
Start with your growth motion. If you're a SaaS or subscription business activating existing users, a referral tool close to GrowSurf's model fits best: Rewardful if you're on Stripe or Paddle, Viral Loops if you want template-based campaigns, Referral Rock if you want advisor support to run it for you.
If you're an ecommerce brand and the job is customer referral, ReferralCandy and Refersion cover Shopify tracking and payouts well, and UpPromote runs it all natively inside your store. Friendbuy makes sense when you want referral and loyalty on one platform.
If your growth is creator-led, though, GrowSurf's user-refers-friend model isn't the shape you need. Modash finds the creators, attributes their Shopify sales at the order and discount-code level, and pays them across 180+ countries as vendor of record, all in one workflow. Try Modash free and see whether it fits your program before you commit.
