Rewardful vs FirstPromoter: Which Is Best for SaaS in 2026?

Rewardful and FirstPromoter both charge $49 a month to start, both track affiliates with 60-day cookies by default, and both publish their own comparison pages for this exact search, each with an obvious favorite. This page is the version you would send a friend: the verified numbers, the trade-offs each vendor's page leaves out, a score per criterion, and the one option neither of them mentions.

Quick answer: Rewardful or FirstPromoter?

Rewardful is the better pick for most Stripe and Paddle SaaS in 2026: it includes its REST API on the $49 tier, states a 0% transaction fee plainly, and gives 50% more affiliate-revenue headroom at the entry price. Pick FirstPromoter if you bill through Chargebee, Recurly, or Braintree, or if you need MRR-based commissions and tax forms handled in-product. On the four criteria below, the rubric finishes Rewardful 2, FirstPromoter 1, with attribution a tie — and if you want to skip the subscription entirely, Affitor charges $0/month until your affiliates generate their first $10,000.

Every number on this page was checked against each vendor's live pricing page on July 5, 2026.

Pricing: Rewardful vs FirstPromoter — same floor, different ceilings

Both ladders look identical from a distance: $49, then $99, then $149 and up. The differences live in what each rung caps and what it unlocks. Both vendors meter you by monthly affiliate revenue, meaning the revenue your affiliates generate, not your total revenue.

Rewardful prices like this:

• Starter, $49/mo: up to $7,500/mo in affiliate revenue, 1 campaign, up to 2 team members
• Growth, $99/mo: up to $15,000/mo, unlimited campaigns and team members, branded affiliate portal
• Enterprise, $149+/mo: over $15,000/mo, phone support, 1-click PayPal payouts

Rewardful states a 0% transaction fee on every tier, plainly, on the pricing page. There is a 14-day free trial, and annual billing gets you two months free, so Growth runs $990 a year paid annually instead of $1,188 paid month to month. No free tier.

FirstPromoter uses the same three rungs with different limits:

• Starter, $49/mo: up to $5,000/mo in affiliate revenue, 3 campaigns, 1,000 affiliates, and no API
• Business, $99/mo: up to $15,000/mo, unlimited campaigns and affiliates, API and webhooks, tax form handling
• Enterprise, from $149/mo: above $15,000/mo

The trial is 14 days with no credit card required. No free tier. FirstPromoter's pricing page does not state a transaction fee either way; Rewardful's does. (Rewardful's page, for its part, never says whether its trial needs a card, which is why we only make that claim for FirstPromoter.)

Look past the headline price and the entry tiers ration different things. Rewardful's Starter allows 1 campaign and up to 2 team members but gives you more revenue headroom. FirstPromoter's Starter allows 3 campaigns and up to 1,000 affiliates but takes the API away and caps revenue lower. Which constraint bites first depends on whether your bottleneck is people, programs, or sales volume.

Two honest observations. First, FirstPromoter's $5,000/mo entry cap is the lowest in its peer group, so upgrade pressure arrives earliest: if your affiliates drive $6,000 in sales next month, you are over FirstPromoter's Starter cap and shopping for the $99 tier, while on Rewardful you are still $1,500 under the limit. Second, both ladders meter success. The better your program performs, the sooner you pay more, whether or not your margins moved.

Verdict: Rewardful takes pricing — 50% more affiliate-revenue headroom at the same $49, and the only transaction-fee policy stated in writing. Score: Rewardful 1, FirstPromoter 0.

Attribution: Rewardful vs FirstPromoter — two cookie models, one blind spot

This criterion is closer to a tie than either vendor's marketing suggests.

Rewardful attribution is cookie-based with a default 60-day window, and you can choose first-touch or last-touch credit. That choice matters more than it sounds: first-touch pays the affiliate whose link the buyer clicked first, which protects reviewers and content sites; last-touch pays the most recent click, which tends to favor whoever the buyer touched on the way to checkout.

FirstPromoter sets _fprom_* cookies, also with a 60-day default. The conversion is recorded at signup. Identity does not ride Stripe metadata natively.

A 60-day window is generous: a click on July 5 still credits the affiliate if the signup lands by early September. For the common case, one browser, one device, a signup inside the window, both systems work.

The shared weakness is that cookie-based attribution breaks on cookie loss, and the failure is silent. The buyer switches devices, clears cookies, or converts after the window closes; the affiliate loses credit, and no dashboard shows you the miss. Neither vendor is worse than the other here. It is the same model with the same blind spot, so do not let either compare page convince you tracking is the reason to switch between these two.

Verdict: a tie — the same 60-day cookie model with the same silent failure mode; tracking is not the reason to pick either. Score: Rewardful 1, FirstPromoter 0, one tie.

API and integrations: Rewardful vs FirstPromoter — day-one API vs broader billing

Rewardful includes its REST API on every tier, including the $49 Starter. It is built for Stripe and Paddle billing, and its setup is the simplest in the category for a Stripe SaaS.

FirstPromoter covers five billing providers (Stripe, Paddle, Recurly, Chargebee, Braintree), but gates the API and webhooks to the $99 Business tier. The $49 plan is dashboard-only.

That gives you two clean decision rules. If your integration is code-first and your budget is $49, Rewardful is the only one of the two that gives you an API at that price. If you bill through a provider Rewardful does not support, Rewardful is off the table and FirstPromoter is not — billing fit overrides every other criterion on this page, because a tracker that cannot see your invoices tracks nothing.

Worth knowing if you automate with AI agents: neither product ships an agent-completable integration path. As of the June 2026 audit, no official MCP server was found for either, and neither publishes a runbook an agent could execute and then verify on its own. Both APIs are human-developer surfaces.

Verdict: Rewardful takes the API criterion — programmatic access from the first dollar, where FirstPromoter charges $99 to open the same door; but if your billing is not Stripe or Paddle, FirstPromoter wins this section by default. Score: Rewardful 2, FirstPromoter 0, one tie.

Payouts and tax: Rewardful vs FirstPromoter — the back office decides

FirstPromoter has the deeper back office. Commissions can be MRR-based, which fits subscription pricing well. Tax form handling is included from the $99 Business tier, fraud detection is part of the product, and automatic payouts arrive on Enterprise.

Rewardful keeps this surface smaller. On its pricing page, payout automation appears as 1-click PayPal payouts on the $149+ Enterprise tier, and no payout automation is listed below that.

For a program with more than a handful of affiliates, the tax-form question is not cosmetic: someone has to collect the paperwork before payouts go out, and doing it in a spreadsheet is exactly the kind of chore that stops happening by month three.

One caution while you research: FirstPromoter's own compare pages knock Rewardful for basic fraud protection and limited email functionality. Those claims come from a competitor's marketing page, so weigh them accordingly, and apply the same skepticism to the Affitor section below.

Verdict: FirstPromoter takes payouts and tax — MRR-based commissions, in-product tax forms from $99, and fraud detection make it the stronger back office. Final score: Rewardful 2, FirstPromoter 1, one tie.

Who should pick which

Pick Rewardful if you bill through Stripe or Paddle, want API access from the first dollar, and value a transaction fee that is stated as 0% rather than left unsaid. It is the default "cheap and simple" pick for Stripe SaaS and carries the strongest brand recognition among indie hackers. Its Starter cap gives you 50% more affiliate-revenue headroom than FirstPromoter's at the same price.

Pick FirstPromoter if you bill through Chargebee or another provider beyond Rewardful's Stripe/Paddle pair, want MRR-based commissions, or want tax forms handled inside the product instead of in a spreadsheet. It is also the only one of the two that gives you more than one campaign at $49, with three on Starter against Rewardful's one. Budget $99/mo from the start if you need the API, and expect to outgrow the $5,000/mo Starter cap first if you do not.

Neither choice is a mistake at this price. Both are mature products aimed squarely at subscription SaaS, and for many teams the deciding factor is simply which billing provider they already use. If you are also weighing the rest of the field, the best Rewardful alternatives for SaaS compares five tools side by side.

The option neither compare page mentions

Rewardful's comparison article and FirstPromoter's compare pages measure the two against each other and a few look-alikes. Neither mentions Affitor, so here is that section, written with the same rules as everything above.

Affitor drops the subscription entirely. It costs $0/mo with $0 setup, and you pay nothing until your program earns its first $10,000 through affiliates, then 3.5% on affiliate-driven sales only. There is no tier ladder to outgrow because there are no tiers, and no revenue cap that turns your affiliates' good month into your upgrade email.

Attribution works differently too. Instead of a cookie window, attribution rides Stripe metadata: the click ID and customer key travel on the Stripe Checkout Session itself, anchored to a signup-based identity chain (click, then hashed email, then Stripe customer) that survives cookie loss.

And the integration is agent-verifiable, shipped and live today, not roadmap: a skill.md runbook an AI agent can complete end to end, an affitor CLI, and a self-verify loop that fires a synthetic click, lead, and sale, then returns integration_verified: true from the readiness endpoint. As of the June 2026 audit, no other platform in this comparison ships an equivalent. The full Stripe wiring is walked step by step in How to create a Stripe affiliate program.

Program operations follow the same keep-it-small idea: one flat partner table holds active partners, applications, and pending invites, and partner invites come pre-written from your program's real terms (commission rate, attribution window, payout threshold) — paste emails or import a CSV and send.

Now the trade-offs, because this page promised them:

• Affitor is Stripe-native. If you bill through Chargebee or another provider, FirstPromoter covers more rails than Affitor does.
• Percentage fees flip at scale. At $15,000/mo of affiliate-driven revenue, Affitor's 3.5% works out to $525/mo, while Rewardful Growth is a flat $99 with a 0% fee. A flat subscription is cheaper for a large, predictable program. Paying $0 until the program works is cheaper for a new one that might earn nothing. Do the math for your own volume before choosing.

FAQ

Is Rewardful cheaper than FirstPromoter?

They cost the same on paper — both start at $49/month and step to $99 and $149+ (as of July 5, 2026) — but Rewardful gives you more for it at the entry tier: a $7,500/month affiliate-revenue cap versus FirstPromoter's $5,000/month, and API access that FirstPromoter reserves for its $99 plan. FirstPromoter gives you 3 campaigns at $49 where Rewardful allows 1.

Does FirstPromoter charge transaction fees?

FirstPromoter's pricing page does not state a transaction fee either way (as of July 5, 2026). Rewardful, by contrast, states a 0% transaction fee on every tier explicitly. Neither page shows any per-transaction charge on top of the subscription.

Which is better for a Stripe SaaS, Rewardful or FirstPromoter?

Rewardful is the better pick for most Stripe or Paddle SaaS: it has the simplest setup in the category, includes its REST API on the $49 tier, and gives 50% more affiliate-revenue headroom at the entry price. FirstPromoter wins when you bill through Chargebee, Recurly, or Braintree, or need MRR-based commissions and tax forms.

Does FirstPromoter have an API on the $49 plan?

No. FirstPromoter's $49 Starter tier is dashboard-only; the API and webhooks are gated to the $99 Business tier and up (as of July 5, 2026). Rewardful includes its REST API on every tier, including the $49 Starter.

Is there an alternative to both Rewardful and FirstPromoter?

Affitor drops the subscription both of them charge: $0/month with a 3.5% fee on affiliate-driven sales that starts only after your first $10,000 in affiliate revenue. It anchors attribution to the signup and Stripe customer record instead of a 60-day cookie, so referrals survive cookie loss.

How do Rewardful and FirstPromoter track referrals?

Both use cookie-based attribution with a 60-day default window: Rewardful lets you choose first-touch or last-touch credit, and FirstPromoter sets _fprom_* cookies with the conversion recorded at signup. Both share the same blind spot — when the cookie is cleared, blocked, or the buyer switches devices, the affiliate silently loses credit.

What's next

If you are choosing between the two names in the title, take both 14-day trials, wire up one real affiliate link in each, and see which dashboard your team actually opens in week two. The caps, the API gate, and your billing provider will make the decision for you faster than any comparison page.
