GrowSurf
Referral programs priced by participant
GrowSurf runs a refer-a-friend program for a product rather than a one-off giveaway: every participant gets a link, the rewards fire automatically, and the tax paperwork on the payouts is handled. It bills on how many people are in the program rather than on how many you refer, which is unusual and worth understanding before you launch.
Our note
The pricing model is the thing to think hardest about: paying per participant is generous if your referrals convert and punishing if they do not. Run the trial with real traffic before committing to a year.
Viral Loops
Referral programs from templates, per campaign
Viral Loops ships templates for the referral mechanics that already worked for somebody else, a waiting list, a milestone giveaway, a straight refer-a-friend, and lets you run one without building it. Participants import and export as a list, so it plugs into whatever you already send email with. Pricing rises with the number of participants rather than with features.
Our note
Why people weigh these two
- Viral Loops instead of GrowSurf
- Viral Loops builds the same refer-a-friend programs from templates and bills per campaign, starting at $35 a month against GrowSurf's $125.
- GrowSurf instead of Viral Loops
- GrowSurf also prices by participant, but starts at $125 against Viral Loops' $35, a bigger commitment aimed at bigger programs.
Which one should you pick
Pick GrowSurf if the referral program needs to be wired into your own product with custom triggers. Startup is $125 a month, billed yearly at $1,504, for up to 2,500 participants and two referral programs, with rewards that fire on events you define and a 14-day trial that costs nothing.
Pick Viral Loops if you want a mechanic that already worked for somebody else rather than one you design. Plans run $35, $99, $159 and $279 a month, with 30 percent off for annual billing, and every tier includes import and export so the participant list stays usable elsewhere. The trial is free but capped at ten participants, enough to prove the flow works and not enough to run a real campaign.
Common questions
- Is Viral Loops cheaper than GrowSurf?
- At the entry tier, yes: Viral Loops starts at $35 a month, with 30 percent off for annual billing. GrowSurf's Startup plan is $125 a month, billed yearly at $1,504, more than three times Viral Loops' listed starting price.
- Does Viral Loops give me a working referral mechanic without building one?
- Yes, that is its whole approach: templates for a waitlist, a milestone giveaway or a refer-a-friend, ready to launch. GrowSurf gives you the pieces, a link, automatic rewards, an API, but expects you to define the events that trigger them.
- Can I test either one with real participants before paying?
- Not fully on Viral Loops: its 14-day trial is capped at ten participants, enough to check the flow but not to run a campaign. GrowSurf's 14-day trial has no such cap and includes the paid features.
- Which one has the full API on its cheapest plan?
- GrowSurf. Its REST API and webhooks are included on Startup, the entry tier. Viral Loops holds its full API back until the second plan, so the $35-a-month tier does not include it.
