Quick answer
Which free plan fits you?
Three affiliate tools have genuinely free plans: UpPromote (free to $3,000/mo in referral revenue, then 1% to 2% of sales), BixGrow (free to 50 referral orders and 30 affiliates) and Endorsely (free until $1,000/mo in affiliate revenue, then $39). Referly has no free plan. It is $75/mo after a 14-day trial.

UpPromote
Shopify store, under $3,000/mo in referral sales. Free, then a 1% to 2% cut.

BixGrow
Shopify store, want to stay flat-fee forever. Free, then $14.99/mo.

Endorsely
Pre-revenue SaaS. Free until your affiliates earn $1,000/mo.

Affonso
Ready to pay, want the smallest bill. €15/mo billed annually.

Rewardful
Stripe-only and past free. $49/mo, the cheapest known name.
Referly
Past a cap, or you need Stripe and Shopify in one program. $75/mo.
What free costs
Read the cap, not the price
A percentage is cheap while the program is small and the biggest line on the bill once it works. UpPromote's cut passes Referly's flat fee near $3,500/mo.

The shortlist
Six options, three of them free
Free plans first, cheapest paid tier next, ours last. This page is about free, and Referly is not.

UpPromote
The only free plan with a real Shopify install behind it.
- Free to $3,000/mo in referral revenue
- Deepest Shopify-native experience here
- Their directory promotes your program
Limitation: Every paid plan takes 1% to 2% of your referral sales, and the free plan allows one coupon per affiliate. The moment it works, you choose between a cap and a cut.
Best for Shopify stores under $3,000/mo in referral sales.

BixGrow
The cheapest path from free to paid, with no percentage anywhere.
- No per-sale fee on any tier
- $14.99/mo is the cheapest paid tier in the category
- Free plan covers a first program
Limitation: Shopify only, and the free plan caps at 50 referral orders and 30 affiliates.
Best for Shopify stores that want flat pricing forever.

Endorsely
Free until your affiliates generate $1,000/mo. You pay only once it works.
- The best free-plan structure in the set
- Aimed at Stripe-billed SaaS
- Small, clean, nothing to learn
Limitation: Their own published numbers disagree with each other. Trust the pricing page, not the docs.
Best for pre-revenue SaaS testing whether a program converts.
Open-source WordPress plugins
Self-hosted tracking inside your own WordPress. No licence, your data.
- No subscription, no meter
- Full data ownership
- Extensible if you have developers
Limitation: You host, secure, update and support it yourself. No payouts, no tax forms, no support desk. The cost moves from the invoice to your calendar.
Best for teams with WordPress developers and spare time.

Affonso
Not free, but cheaper than most free plans' first paid tier. €15/mo annually.
- The cheapest paid entry anywhere
- 14-day trial first
- Covers a Stripe program's basics
Limitation: Not free, and the Launch plan caps affiliate revenue at $1,000/mo.
Best for founders who decided to pay but want the smallest bill.
Paid. On this page for one honest reason: it is where free plans send you when they run out.
- Direct import from eight tools, so leaving free is painless
- Coupon tracking and fraud checks on every plan
- Stripe and Shopify in one program
Limitation: No free plan. $75/mo, with a $10,000/mo affiliate revenue cap on Startup. If free is a hard requirement, three tools above qualify and this one does not.
Best for programs that outgrew a free tier's cap.
Before you pick
What free actually costs
What is the meter?
Revenue, orders or affiliates. Whichever breaks first is the real price.
Percentage or flat?
2% of $30,000/mo is $600/mo. Flat wins past roughly $3,750/mo.
Can you get your affiliates out?
No export means the free plan is the trap, not the offer.
Who pays the partners?
Most free plans track referrals and leave the payouts and W-8s to you.
What does support look like at $0?
A community Discord is not an SLA, and affiliate disputes spread.
