If you pay for clicks, a landing page builder is not really a design tool — it is the place your ad spend either gets measured and improved, or doesn't. Unbounce, Leadpages, Instapage and Carrd take four very different approaches to that job, starting with how they charge you for visitors.
Starter, billed annually. A/B testing starts on Experiment at $112/mo billed annually.
Pro (publishing only). A/B testing starts on Grow at $99/mo, $79/mo billed annually.
Create, billed annually ($99/mo monthly). A/B testing starts on Optimize at $159/mo billed annually.
Pro Standard, billed yearly — there is no monthly billing. That is per year, not per month.
| Unbounce | Leadpages | Instapage | Carrd | |
|---|---|---|---|---|
| Best for | Marketers testing paid-traffic pages and variants | Small businesses that want a predictable bill with testing included | PPC and growth teams managing many campaign pages | Solo creators validating one offer as cheaply as possible |
| Entry price | Starter $29/mo ($22/mo billed annually) | Pro $29/mo (publishing only; annual billing saves 20%) | Create $99/mo ($79/mo billed annually) | Free; Pro Standard $19/year (yearly billing only) |
| Cheapest plan with A/B testing | Experiment $149/mo ($112/mo billed annually) | Grow $99/mo ($79/mo billed annually) | Optimize $199/mo ($159/mo billed annually) | Not offered on any plan |
| How visitors are charged | Metered: 500 / 20,000 / 30,000 / 50,000 visitors per month by tier. Conversions are unlimited | Not metered: unlimited visitors and leads on every plan | Metered: 15,000 / 30,000 / 50,000 unique visitors per month by tier. Pages, conversions and contacts are unlimited | No visitor cap published; plans are priced by number of sites |
| What happens over the limit | Pages keep running; $80 per additional 10,000 visitors or part thereof (rate in effect since Nov 10, 2025) | Nothing — there is no visitor limit to exceed | No published per-visit overage rate. The vendor's help center says accounts can be locked at the limit, and pages may be unpublished if you exceed it across multiple cycles | No published visitor limit |
| Ad-to-page matching | Dynamic text replacement from Experiment; Smart Traffic AI routing on Optimize ($249/mo) | Dynamic text replacement from Grow; Smart Traffic and heatmaps on Optimize ($199/mo) | Dynamic text replacement on Optimize; heatmaps and ad-to-page personalization centered on Convert (custom pricing) | Not offered — one static page per site |
| Free option | No free plan — 14-day trial, no card required | No free plan — 7-day trial, card required | No free plan — 14-day trial, card required, capped at 2,500 visitors | Yes — up to 3 sites on a Carrd subdomain (no forms on the free plan) |
| Checkout on the page | Via integrations | Built-in Stripe checkout | Not built in — via integrations | Payment forms via Stripe Checkout on Pro Plus ($49/year) |
| Trade-off to know | The two cheapest tiers cannot A/B test, and a traffic spike becomes an overage line on your bill | The $29 and $49 tiers publish pages but cannot test them; plan names and prices were overhauled in 2026, so old reviews are stale | The entry tier cannot test, the top features are quote-priced, and exceeding your visitor cap risks a lock rather than a fee | Fast and nearly free, but no testing, no dynamic content and only one page per site |
Prices checked November 2026, in USD before tax, from the vendors' published pricing. Leadpages' on-page card prices have been reported to differ by region and date from its FAQ prices — the figures above follow its FAQ, so confirm the number on your own checkout screen before budgeting. Plans change — always confirm the current price, visitor allowance and what's included on the vendor's site before you buy.
Unbounce is built around a simple split: you can publish pages cheaply, but you pay more — in plan tier and in visitors — as soon as you start optimizing. Starter ($29/mo, $22/mo billed annually) covers 5 pages and just 500 visitors a month. Build ($99/mo, $74/mo annually) raises that to unlimited pages and 20,000 visitors, with popups, sticky bars and custom code — but still no A/B testing. Testing arrives on Experiment ($149/mo, $112/mo annually): unlimited A/B tests, manual traffic splits and dynamic text replacement, which swaps page copy to match the ad or search term a visitor arrived from. Optimize ($249/mo, $187/mo annually) adds Smart Traffic, which routes each visitor to the variant its model expects to fit them best; Unbounce publishes an average improvement figure for it, which we treat as a vendor claim, not a result you should budget on. Every plan includes unlimited conversions — the meter is visitors, charged at $80 per additional 10,000 (or part thereof) if you go over.
People searching for a Leadpages alternative usually land on one of two facts, so here they are plainly: Leadpages does not meter visitors at all, and its current pricing has two halves. The publishing half is Pro ($29/mo) with 25 pages and Business ($49/mo) with 50 pages — both publish pages, popups and sites with unlimited traffic, but neither can A/B test. The testing half starts at Grow ($99/mo, $79/mo billed annually): unlimited pages, manual A/B testing with up to six variants per page, dynamic text replacement and lead enrichment. Optimize ($199/mo, $159/mo annually) adds multivariate testing, Smart Traffic routing and heatmaps. A larger Scale tier is listed in the vendor's FAQ at $399/mo. There is no free plan, and the 7-day trial requires a card. If you are comparing Leadpages with a tool you already use, the honest comparison is not $29 vs. $29 — it is your current testing plan vs. Grow.
Instapage aims at teams that run many campaigns at once: reusable Instablocks so a section is built once and updated everywhere, real-time collaboration, and server-side A/B testing, which avoids the flicker some browser-side tests show visitors. The pricing, though, gates almost all of that. Create ($99/mo, $79/mo billed annually) includes 15,000 unique visitors a month and unlimited pages — but no A/B testing at all. Optimize ($199/mo, $159/mo annually) is where testing, dynamic text replacement and multi-step forms start, at 30,000 visitors, with an expanded 50,000-visitor version at $299/mo ($239/mo annually). Heatmaps, global blocks and 1:1 ad-to-page personalization are centered on Convert, which is quote-priced. The trial lasts 14 days, needs a card, and stops at 2,500 visitors — exceed that and the trial converts to a paid plan. On paid plans there is no published overage rate: the vendor's help center says an account at its limit can be locked, so the risk on a spike is interruption, not a fee.
Carrd makes one-page sites, and its pricing is in a different universe from the other three: Pro Standard is $19 per year (not per month), covering 10 sites with a custom domain, forms, widgets, embeds and third-party analytics. Pro Lite ($9/year) removes branding but has no custom domain and no forms, and Pro Plus ($49/year) covers 25 sites and adds advanced forms — including payment forms routed to Stripe Checkout — plus password protection and redirects. The free plan publishes up to 3 sites on a Carrd subdomain, but with no forms it works as a link page, not a lead page. What Carrd does not do, on any plan, is the optimization half of this category: no A/B testing, no dynamic text replacement, no heatmaps, and no built-in lead management beyond what you embed or connect yourself. That is a fair trade while an offer is unproven and ad spend is near zero. It stops being one once you are paying for enough traffic that testing would pay for a dedicated builder.
At 5,000 visitors a month, every tool here fits. At 25,000, Unbounce's testing plan is Experiment ($112/mo billed annually), Leadpages is still Grow ($79/mo), and Instapage is Optimize ($159/mo). At 60,000 in a peak month, Unbounce Optimize ($187/mo) plus one $80 overage block comes to about $267 for that month, Leadpages is still $79, and Instapage is past its published 50,000-visitor tier altogether. Choose for the spike, not the quiet month.
At an illustrative $2 cost per click, 25,000 visitors means roughly $50,000 of monthly ad spend — against which a $79–$159 builder is 0.16–0.32% of the budget. At that scale, running ads to a plan that cannot test is usually the expensive option, whatever the subscription says. At near-zero ad spend, the same math runs the other way, and Carrd's $19/year is the rational starting point.
Three different answers: Unbounce charges you ($80 per 10,000 extra visitors, rounded up) and keeps serving. Leadpages does nothing — there is no cap. Instapage publishes no overage rate and its help center describes accounts being locked at the limit. Decide in advance which failure mode you can live with.
Unbounce offers 14 days without a card; Instapage 14 days with a card and a 2,500-visitor trial cap; Leadpages 7 days with a card. Send a small, real slice of ad traffic to a page built in your trial — not a demo page — and check load behavior in PageSpeed Insights and the full path from click to lead in your CRM before you commit.
It depends on why you're leaving. If you want testing at a similar price without a visitor cap, compare the other tools' testing tiers directly: Unbounce Experiment ($112/mo billed annually, 30,000 visitors) is the closest like-for-like builder, and Instapage Optimize ($159/mo billed annually) suits larger PPC teams. If price itself is the reason, Carrd ($19/year) covers a single static offer — without any testing. Note that Leadpages itself has no visitor cap, so "unlimited traffic" alone is not a reason to switch away from it.
Because hosting and serving your pages costs the vendor more as traffic grows, and because advertisers' willingness to pay scales with traffic. Unbounce and Instapage meter unique monthly visitors; Leadpages and Carrd don't. Metering is not unfair in itself — what matters is the overage rule: a published per-visit fee (Unbounce), no fee because there is no cap (Leadpages), or no published fee with a possible account lock (Instapage).
For a first test of one offer, yes — a Carrd Pro Standard page ($19/year) with a form and an external analytics tag can collect leads from a small campaign. The ceiling is learning: with no A/B testing, no dynamic text replacement and one page per site, you can't systematically improve the page your ads pay to fill. Once monthly ad spend reaches the point where a single-digit percentage change in conversion is worth more than a builder subscription, a dedicated tool earns its price. No tool on this page guarantees that improvement, though — testing only tells you which version performs better.
No. Features like Unbounce's Smart Traffic and Leadpages' Smart Traffic automate the allocation step — sending each visitor to the variant the model favors — instead of splitting traffic evenly until a test concludes. They still need you to create meaningfully different variants, and the improvement figures attached to them are vendor-reported averages, not promises for your campaign. Both sit on higher tiers, so price them as upgrades, not defaults.
None of the four publishes a guaranteed load-time figure we could verify, so we don't rank them on speed claims. In practice, your page weight — image sizes, embedded scripts, number of tracking tags — dominates. Whichever builder you pick, run the published page through Google PageSpeed Insights before sending paid traffic, and re-check after adding pixels and embeds.
Because this guide is compiled from the vendors' published specifications and pricing, not from hands-on testing. Where a judgment appears — for example, that overage rounding makes small spikes expensive — it is arithmetic on the published prices and caps, shown next to it so you can check it yourself.
