Every sale starts with a lead, and a landing page is where a click becomes a lead. This is the top-of-funnel capture layer of your revenue stack: standalone tools built to turn traffic into email subscribers. This is a comparison of the four worth buying, judged on opt-in conversion and speed to publish. Here’s what to buy.
Landing-page coverage usually gets buried inside broad “funnel builder” or “website builder” posts. That mixes jobs. A lead-capture page has one purpose: get the email address. So I judge these on conversion features (forms, popups, A/B testing), how fast you can publish, and whether you need a separate email tool. Everything else is decoration.
The bottom line (buy / skip)
Best free option: Kit (formerly ConvertKit). Unlimited landing pages and forms free up to 10,000 subscribers — and it’s a full email platform, so capture and nurture live in one tool. Unbeatable for a solopreneur starting out.
Best cheapest paid: Carrd. $19/year gets you a one-page opt-in with a real form and custom domain. Nothing is cheaper.
Best pure conversion optimizer: Unbounce — AI Smart Traffic routing and unlimited conversions, if you drive real paid traffic.
Best dedicated page builder with A/B testing: Leadpages — but the full plan now starts at $99/mo.
What makes a lead-capture tool convert
Four things matter for turning traffic into subscribers:
- Forms and popups. Inline forms, modals, slide-ins, exit-intent — the more capture surfaces, the more leads.
- Opt-in conversion features. A/B testing, dynamic text, AI variant routing. Small lifts compound.
- Speed to publish. How fast from idea to live page? Momentum matters for a solo operator.
- Do you need a separate ESP? Some capture the lead but can’t email it. That’s a hidden second bill.

Kit: capture and nurture in one free tool
Here’s the number that matters: 10,000 subscribers, free. Kit’s free Newsletter plan gives you unlimited landing pages and forms, unlimited email broadcasts, and tagging/segmentation — up to 10,000 subscribers, at $0. That’s not a crippled trial; it’s a real business tool.
- Free: unlimited landing pages and forms, broadcasts, tagging, up to 10,000 subscribers.
- Creator — $33/mo monthly ($390/yr) at 1,000 subscribers: unlimited visual automations and sequences, SMS, A/B subject-line testing.
The reason Kit tops this list: it’s the only one that captures and nurtures. Every other tool here grabs the lead and then needs a separate email platform to do anything with it — a second subscription. Kit wires your opt-in forms straight into automations at no cost. Tightest capture-to-nurture loop of the four, and free to start.
Who it’s for: any solopreneur building an email list who wants capture and email in one tool. Who it’s not for: people who need heavy design control or standalone CRO features.
Carrd: the cheapest real opt-in page
Carrd is dead simple and absurdly cheap. It builds one-page sites, and with the right tier, real opt-in forms.
- Free: up to 3 sites — but no custom domain and no forms.
- Pro Lite — $9/year: removes branding — but still no forms or custom domain.
- Pro Standard — $19/year: this is the one you want — adds forms, custom domains, and embeds.
Important: for actual lead capture you need Pro Standard at $19/year, not the $9 Pro Lite (which has no forms). At $19 for a whole year, it’s the cheapest way to put a real opt-in page online. Carrd has no native email, so you connect an ESP — it integrates with Mailchimp, Kit, ActiveCampaign, and others. For a single high-converting opt-in page on a shoestring, nothing beats it.
Who it’s for: budget solopreneurs who want one clean opt-in page fast. Who it’s not for: anyone needing multiple pages, popups, or built-in email.
Unbounce: the conversion optimizer
Unbounce is for people who spend on traffic and want to squeeze every conversion out of it. Its edge is AI-driven optimization.
- Starter — $29/mo monthly, $22/mo annual: 5 pages, up to 500 traffic volume, 1 user.
- Build — $99/mo monthly, $74/mo annual: unlimited pages, up to 20k traffic, popups, sticky bars, multi-step forms, AI copywriting.
- Optimize — $249/mo ($187 annual): AI Smart Traffic routes each visitor to the variant most likely to convert.
Note the 2026 changes: the old “Launch” plan is now “Build,” and — a genuine win — conversions are now unlimited on all plans (no more conversion caps). Pricing is by monthly traffic volume. Unbounce isn’t an email tool; it captures and pushes to your ESP. It’s overkill for someone just starting a list, but if you’re running paid ads, Smart Traffic can pay for itself.
Who it’s for: marketers driving paid traffic who need serious CRO. Who it’s not for: early-stage solopreneurs (too much tool, too much cost).
Leadpages: the dedicated page builder
Leadpages is a focused landing-page and lead-gen builder with a big 2026 restructure — the old $37 “Standard” plan is gone.
- HTML Pub Starter — $10/mo ($8 annual): a lighter publishing product, 5 pages, 1 domain.
- Grow — $99/mo ($79 annual): unlimited pages, manual A/B testing, dynamic text replacement, lead enrichment.
- Optimize — $199/mo ($159 annual): Smart Traffic AI routing, heatmaps.
Every plan has unlimited traffic with no visitor caps — nice. A/B testing starts at the Grow tier ($99/mo), and the AI Smart Traffic routing is at Optimize. Like Unbounce, it captures leads and hands them to your ESP; it’s not an email tool itself. It also shows up in my ClickFunnels alternatives comparison, but there it’s framed as a funnel builder — here the job is pure list-growth pages.
Who it’s for: people who want a dedicated page builder with testing and don’t mind $99/mo. Who it’s not for: budget starters (Kit or Carrd win) or those needing native email.
So which lead-capture tool should you buy?
- Building an email list from scratch → Kit. Free up to 10k subs, and it emails them too. My pick for most solopreneurs.
- Cheapest single opt-in page → Carrd Pro Standard. $19/year, done.
- Running paid ads, need CRO → Unbounce. Smart Traffic earns its cost on real traffic.
- Want a dedicated page builder with testing → Leadpages Grow.
Then close the loop. Capture is step one — the lead only pays off when you nurture it. Send new subscribers into an email platform built to sell, and hand sales-ready leads to your CRM. A list you capture but never email is just a bigger spreadsheet.
