TL;DR: Carrd fits simple one-page sites at $0, then $9/$19/$49 per year β custom domains start at Pro Standard $19/year, not at $9. Unbounce fits paid-media teams that will buy Build or Experiment and will pay for traffic envelopes and testing. Leadpages fits creators who want a published self-serve landing-page ladder. Instapage fits teams that will pay Instapage rates for experimentation and personalization rather than a $19-a-year page.
A landing page builder is the tool that publishes a campaign URL and measures conversion. It is not a full website builder (see that comparison) and it is not an ecommerce platform.
Every entry uses the same fields: published pricing, testing, traffic envelope, domain/branding and the main limitation. The order below is not a quality ranking. Carrdβs $0 then $19/year custom-domain row sits first. Unbounce, Leadpages and Instapage follow as paid media tools.
Landing page builders compared at a glance
| Provider | Published pricing | Testing | Best for | Link |
|---|---|---|---|---|
| Carrd | Free (3 sites, carrd.co URL). Pro Lite $9/year. Pro Standard $19/year (custom domain, forms). Pro Plus $49/year | No Unbounce-style A/B product | Simple one-pagers and link pages | Visit β |
| Unbounce | Build / Experiment / higher rows on unbounce.com/pricing. Third-party reads in 2026 put annual Build around the mid-$70s/mo; confirm the live toggle | A/B and Smart Traffic sit on Experiment+, not on the cheapest Build row | Paid-media landing pages with tests | Visit β |
| Leadpages | Published self-serve plans on leadpages.com/pricing | Plan-gated | Creators and small marketing teams | Visit β |
| Instapage | Published and sales-assist plans on instapage.com/pricing | Experimentation is the commercial story | Teams personalising many campaign URLs | Visit β |
Carrd plan names and yearly prices were read from Carrdβs own Pro docs on 14 September 2026. Unbounce dollar amounts move with monthly/annual toggles β use the live page, not a screenshot from March.
One product is $19 a year for a custom domain. The others are monthly media tools.
A page is not an experiment
Carrd publishes a page. Unbounce Experiment publishes variants and allocates traffic. If the brief is βship a URL this afternoon,β Carrd or Leadpages is the shape. If the brief is βbeat control by week four,β you are buying Unbounce/Instapage.
The four providers in detail
1. Carrd
$0 THEN $19/YEAR FOR A REAL DOMAIN
Best for: a single offer, waitlist or personal page when you do not need A/B testing as a product.
| Published pricing | Free: 3 sites on a carrd.co URL. Pro Lite $9/year (branding off, still check domain rules). Pro Standard $19/year: custom domain, forms, analytics. Pro Plus $49/year: advanced forms, downloads |
| Testing | None as a built-in experimentation suite |
| Traffic envelope | Carrd does not sell a 20k-visit cap the way Unbounce Build does |
| Free plan / trial | Permanent Free with vendor URL and footer |
| Main limitation | Pro Lite $9 is widely mis-sold as βcustom domain.β Standard $19 is the domain row on Carrdβs docs |
- Budget $19/year if you care about yourdomain.com.
- Forms that start a CRM workflow may still need Zapier/Make on top.
- Do not put a 12-variant paid campaign on Carrd and expect Unbounce reports.
2. Unbounce
BUILD VS EXPERIMENT
Best for: performance marketers who will pay a monthly envelope for pages, popups and tests.
| Published pricing | unbounce.com/pricing β Build is the page row; Experiment adds unlimited A/B and Smart Traffic. Annual vs monthly changes the number |
| Testing | The reason to leave Carrd. Not on the cheapest Build row |
| Traffic envelope | Printed unique-visitor caps per plan. Overage is how bills jump |
| Free plan / trial | 14-day style trial. Not a $0 production page like Carrd |
| Main limitation | Buying Build then discovering tests live on Experiment is the classic miss |
- If you will not run tests, Carrd or a website builder is cheaper.
- Count unique visitors from ads, not βthe internet.β
- Smart Copy / AI features follow the plan grid β read it.
3. Leadpages
CREATOR LADDER
Best for: small marketing teams and creators who want templates, pop-ups and a published self-serve bill.
| Published pricing | leadpages.com/pricing β self-serve named plans |
| Testing | Plan-gated. Confirm before you assume Unbounce-level experiments |
| Traffic envelope | Read the live cap. Leadpages has historically used visitor or conversion gates |
| Free plan / trial | Trial. Production is paid |
| Main limitation | Not Instapage personalization. Not Carrdβs $19/year |
- Use Leadpages when the team already likes the template library.
- Check whether paid ads volume fits the cap in month one.
- Website-builder overlap: if you already pay Wix/Squarespace, you may not need a fourth page tool.
4. Instapage
PERSONALIZATION AT PAID-MEDIA SCALE
Best for: teams running many campaign URLs that must change by source, audience or experiment.
| Published pricing | instapage.com/pricing β mix of published and sales-assist rows |
| Testing | Core product story |
| Traffic envelope | Plan-gated; read before you point paid traffic |
| Free plan / trial | Trial / demo. Not Carrd Free |
| Main limitation | You do not buy Instapage to save money versus Carrd |
- Shortlist Instapage only if personalization is in the brief.
- Ad-ops integration quality matters more than template count.
- Compare Experiment Unbounce vs Instapage on the testing line, not on the logo.
Kurums Match: which one fits your situation
I need a URL this afternoon for $0β$19/year
Carrd Free or Pro Standard.
We run ads and will test two variants
Unbounce Experiment (not Build) or Instapage. Size the visitor cap.
We already pay Wix or Squarespace
Use that builderβs landing page first. Add Unbounce only if testing is the gap.
We personalise dozens of paid URLs
Instapage.
Buying tip: write expected unique visitors from paid in month one. That number kills the wrong plan faster than a template gallery.

Carrd Pro docs and vendor pricing pages, 14 September 2026. Unbounce dollar bands referenced as βconfirm liveβ because toggles move. No paid placement. Kurums did not run an ad test on all four.
Order is cheapest published production path first. No badge reflects a commercial relationship.
Frequently asked questions
Does Carrd $9 include a custom domain?
Carrdβs own Pro docs put custom domains on Standard ($19/year), not Lite ($9/year).
Is Unbounce Build enough?
For shipping pages, yes. For A/B and Smart Traffic, the public grid points at Experiment and up.
Should this replace our website builder?
No. Campaign URLs and the company site are different jobs.
What about Framer?
Framer is closer to a website builder. It is not in this four-product landing-page set.
Did we measure conversion lift?
No. Run your own control vs variant.
