Systeme.io vs CartFlows
Pick Systeme.io if you want a hosted suite where funnels, email, courses and a checkout run behind one login, on a genuinely free plan with no sales fees; pick CartFlows if you already run a WooCommerce store and want a better checkout with order bumps, upsells and A/B testing without leaving WordPress.

Quick answer
Systeme.io is our top pick for most people. Systeme.io is the pick if you are starting lean and want a genuinely free way to run funnels, email and courses on one login. It is not built for paid-traffic direct response, where same-URL split testing and payment routing matter more.
- Systeme.io. Best for beginners and solo creators who want a truly free way to run funnels, email and courses in one place. Has a free tier.
- CartFlows. Best for WooCommerce store owners who want a better checkout with order bumps, upsells and A/B testing without leaving WordPress. Has a free tier.

Systeme.io and CartFlows both promise a better funnel with order bumps, one-click upsells and A/B testing, and that overlap is the only reason they land on the same shortlist. Look at what each one actually is and they answer different questions. Systeme.io is a hosted suite you log into: funnels, email, online courses, a membership area, an affiliate program and a checkout, all behind one login, with nothing for you to host. CartFlows is a WordPress plugin that upgrades the checkout on a WooCommerce store you already run. If you are genuinely down to these two, the deciding question is not whose feature list is longer. It is where your business lives: on a platform you rent and never touch a server for, or on a WordPress store you own and manage yourself.
What each one actually is
Systeme.io comes at this from the hosted-platform side. One login covers sales funnels and landing pages, unlimited marketing email, online courses, a membership area, an affiliate program and a checkout, so a solopreneur or course creator stops paying for and wiring together five or six separate tools. It has run since 2018, the vendor says it serves more than 15,000 businesses, and every plan takes 0% of your sales and includes unlimited email sends. The genuinely useful part for a first-timer is the free plan: three funnels, one automation rule and 2,000 contacts at $0 with no card and no expiry. What it is not is a paid-traffic tool. The checkout connects a single payment processor, there is no same-URL split testing, and there is no routing across merchant accounts. Long-term users also flag two soft limits: the design flexibility is basic, and the automation has no conditional branching, so it holds up until you need if-this-then-that logic in an email sequence.
CartFlows comes at the funnel from the other end. It is a plugin from Brainstorm Force, the team behind the Astra theme, and the vendor says more than 800,000 stores run it. Instead of hosting your store it sits on top of WooCommerce and fixes its weakest link, the default checkout. It swaps in a modern multi-step checkout, adds order bumps and true one-click post-purchase upsells and downsells, and runs A/B split testing on any funnel step, from the checkout layout to an upsell offer. It works with the page builder you already use, Elementor, Bricks, Divi, Beaver Builder or the block editor, so there is no second builder to learn. There is a real free version on WordPress.org and a 14-day money-back guarantee on the paid plans. What it is not is a hosted platform or a payment engine: you supply the WordPress hosting, and payments run through whatever single WooCommerce gateway you connect.
Where each one wins
For a coach, consultant or course creator who does not already run WordPress, Systeme.io wins, and it is not close on how quickly you can start. If you are beginning from nothing and want funnels, email, a checkout and a place to host courses without assembling them yourself, buying one hosted login beats bolting a checkout plugin onto a WooCommerce site you would first have to build and secure. Systeme.io is hosted, so there is no WordPress to keep patched, no plugins to keep compatible, and no theme conflict to debug the night before a launch. It also starts free and never charges a cut of your sales, which is a real edge when your revenue is still small. CartFlows has no course player, no email tool and no free-forever hosted funnel, because it was never trying to be the whole business in one place.
For a store already running on WordPress and WooCommerce, CartFlows wins just as clearly. If your catalog, your theme and your content already live on WordPress, moving to a hosted suite like Systeme.io means rebuilding the site somewhere else and carrying courses and memberships you may never use. CartFlows lets you keep the site you have and simply upgrade the checkout, with the two levers that actually raise average order value, order bumps and one-click upsells, plus A/B testing on the funnel steps. Buying a whole hosted platform to fix a WooCommerce checkout would be renting a marketing suite to solve a plugin-sized problem. The deciding question is not which is better software. It is whether you want a platform to run your whole business on, or a better checkout on the store you already own.
On the checkout itself
This is the part worth slowing down on, because it is where the two are more alike than their marketing suggests. Both give you order bumps and one-click post-purchase upsells, both handle subscriptions and coupons, and both run through a single payment processor you connect yourself. Neither rotates a whole checkout server-side against traffic, and neither sends different traffic sources to different merchant accounts. Systeme.io keeps its 0% sales fee across every plan and connects Stripe, PayPal and a handful of regional gateways; CartFlows gives you a modern multi-step checkout and step-level A/B testing inside WordPress. For most sellers the checkout mechanics are close enough to call a wash, and the deciding factor is everything around the checkout, not the checkout itself.
If you run paid traffic: a third name to weigh
There is a gap both of these leave, and for a media buyer it can decide the whole thing. Neither Systeme.io nor CartFlows rotates funnel variants server-side under a single campaign link. Systeme.io does its A/B testing across separate pages, and CartFlows tests across separate funnel steps and URLs, so every time you try a new angle the ad platform can read it as a new page and reset its optimisation, and a fresh URL can send the ad back through review. Neither one routes payments across more than one merchant account either: Systeme.io is single-processor, and CartFlows runs whatever single WooCommerce gateway you connect. If cold paid clicks are how you make your money, those two gaps are the ones that cost you, and ElasticFunnels is the name to put beside these two.
ElasticFunnels is a funnel platform built for teams that live on paid traffic. Same-URL split testing is its lead feature and it is the one both other tools lack: variants rotate server-side under one link, so Meta, Google and TikTok keep their learning and a new test never trips ad review. It is not only a testing tool. It builds the pages, with an AI builder that generates one from a prompt or clones one from a URL, and its checkout runs order bumps, one-click upsells, subscriptions and routing across several merchant accounts, so it covers the payment-routing ground neither of the other two reaches while building and testing pages the way neither of them does. The click, the order, the rebill and the refund land on one timeline with a CRM and attribution, which is the reconciliation work a paid-traffic team usually splits across four separate tools. Every feature is on every plan, and the plans differ by traffic: $97 a month on Starter, $197 on Growth and $497 on Scale, with a 14-day trial and no card required. EF-hosted checkouts carry a 0.5% fee on the revenue you route through them, and sales you run on outside platforms and networks are not charged.
The honest catch is age. ElasticFunnels is newer than either Systeme.io or CartFlows, and there is very little independent third-party review coverage to check its claims against, so until you push real volume through it you are largely taking the vendor's word for it. That is what you would expect of a platform this recent, and it is the one place Systeme.io's years of reviews and CartFlows' 800,000-store install base count for more. It is also why the no-card trial matters here: you can prove the same-URL split testing and the checkout on your own traffic before you move any spend, rather than deciding on the strength of the marketing. The thin outside coverage limits how far you can lean on other people's reviews today. It does not change what the pages, the routing and the split testing do once your own numbers run through them. Our ElasticFunnels review has the full picture.
Pricing, tier by tier
The two do not price the same way, so comparing stickers misleads. Systeme.io bills as a flat monthly subscription with a free plan under it, and every tier keeps unlimited email sends and a 0% sales fee. Free is $0 for 3 funnels, 1 automation rule, 1 custom domain and 2,000 contacts, with no card and no expiry, and it is a working plan rather than a teaser. Startup is $17 a month for 10 funnels, 10 automation rules and 5,000 contacts. Webinar is $47 for 50 funnels, 100 automation rules and evergreen webinars. Unlimited is $97 for unlimited funnels, contacts and automations plus free migration. You still pay your own payment processor's rate on top, but Systeme.io itself never takes a cut.
CartFlows bills annually, not monthly, which a monthly comparison cannot show. There is a free version on WordPress.org for basic funnels. Starter is $99 a year and renews at $149, but it is funnels and checkout only. Pro, at $199 a year renewing at $299, is the tier that actually adds the order bumps, one-click upsells, A/B split testing and smart routing most people come for; a one-time lifetime licence is $699. Suite is $299 a year, renewing at $449, and bundles five more plugins. On top of the licence you still pay your WooCommerce gateway's own rate on every sale, and you pay for WordPress hosting. The billing is the recurring complaint in long-term reviews: licences auto-renew and the refund policy rules out refunds on renewals, so a missed cancellation date can cost a full year. Set a calendar reminder.
Count it against your situation rather than the headline number. For a creator with no site yet, Systeme.io's free plan lets you launch a funnel, an email list and a checkout without spending anything, and its paid tiers stay cheap while charging nothing on your sales. For a store already paying for WordPress hosting, CartFlows Pro at $199 a year is a small add-on to a stack you already run, and moving it all to a hosted platform would mean rebuilding the site. The cheapest way in is Systeme.io's free plan; the cheapest answer depends on whether you were going to run WordPress anyway, and on whether you need courses and email in the same login.
The short version
These two rarely stay on the same shortlist for long, because they fit different businesses. Pick Systeme.io if you want a hosted suite where funnels, email, courses and a checkout live behind one login, nothing is yours to host, and a free plan lets you start at zero with no sales fees; you can live with basic design control and automation that has no conditional branching. Our Systeme.io review covers where the builder and the automations stop. Pick CartFlows if you already run a WooCommerce store and want a better checkout with order bumps, upsells and A/B testing without leaving WordPress; the CartFlows review has the detail on the annual billing and where the free version stops. And if your traffic is cold paid clicks, weigh ElasticFunnels alongside them, because it is the one of the three that split-tests the whole funnel under a single URL and routes payments across accounts. All three, and the rest of the field, are in the full ranking.
Systeme.io: strengths and trade-offs
What works
- A free plan that is not a trial in disguise: 2,000 contacts, three sales funnels, unlimited email sends and no credit card, and it never expires. You can validate an offer end to end before paying a cent.
- One login replaces a stack. Funnels, email, courses, an affiliate program and a checkout come already connected, which for a solo founder cuts both the monthly bill and the wiring work.
- It takes 0% on your sales on every plan, including the free one, so beyond your payment processor's own fees the platform adds nothing per transaction.
- The checkout ships the two levers that raise revenue per sale, order bumps and one-click upsells, plus built-in A/B testing, even on the cheap tiers.
What to watch
- It is not built for cold paid traffic. There is no same-URL split testing, so its A/B test splits visitors across separate URLs and can reset an ad platform's optimisation, and the checkout runs a single processor with no routing across several merchant accounts.
- Design flexibility is basic. The builder is quick to learn but limited, so a premium brand look or a complex layout is where long-term users say it breaks down.
- Automation has no conditional branching. Simple trigger-action rules and tags are fine, but buyers who need if/then email logic or lead scoring tend to outgrow it and move their email to a dedicated tool.
- Email sends run through shared sender pools, so new accounts and cold or imported lists need domain authentication and warm-up, and users report sends being delayed or held when copy trips the spam checks.
CartFlows: strengths and trade-offs
What works
- It upgrades WooCommerce's weakest link. A modern checkout, order bumps and true one-click upsells replace the default checkout, and long-term users credit it with a real lift in average order value.
- It works with the page builder you already use. Elementor, Bricks, Divi, Beaver Builder and the block editor are all supported, so there is no second page builder to learn.
- A/B split testing is built in. You can test any funnel step, from the checkout layout to an upsell offer, and keep the version that converts.
- There is a genuine free version and a 14-day money-back guarantee on the paid plans, so you can build a basic funnel and watch it work before you spend anything.
What to watch
- No same-URL split testing. Its A/B test serves variants that ad platforms can read as separate pages, which can reset campaign learning. That matters most to media buyers optimising cold traffic, and far less to a store selling to an organic or email audience.
- Payments run through a single WooCommerce gateway with no routing across merchant accounts. High-risk and high-volume sellers who spread payments across several MIDs will need a different platform for that; a store on one Stripe account will not miss it.
- The billing is the sore point. Licences auto-renew and the refund policy rules out refunds on renewals, so a missed cancellation date can cost a full year. Set a calendar reminder before your renewal.
- It is WooCommerce-only. CartFlows needs WordPress and WooCommerce running, so it is not an option off that stack, and it is one more plugin to keep updated and compatible with your theme and blocks.
