What to look for
Easy drag-and-drop
Build and edit pages fast without code or a designer, with templates that convert out of the box.
Built-in follow-up
Email/SMS automation so leads don't go cold the moment they opt in - the difference between a page and a funnel.
Checkout & upsells
Order forms, order bumps and one-click upsells to lift average order value on the same platform.
Page speed
Fast-loading pages convert better and rank better - heavy builders cost you sales and ad spend.
A/B testing
Split-test headlines, layouts and offers to improve conversion over time, not guess.
Total cost
An all-in-one (GoHighLevel) can replace separate funnel + email + CRM bills, often cheaper overall.
The best, ranked
GoHighLevel
GoHighLevel's funnel and website builder rivals ClickFunnels - but it also includes your CRM, email, SMS, calendars and automation in one flat fee, so a lead that opts in is instantly nurtured rather than dropped into a disconnected tool. You can even import ClickFunnels pages in a click. For UK businesses that want funnels and the system to follow up and convert those leads, nothing else offers this much for the money. The builder isn't the absolute fastest and there's a learning curve, but the end-to-end integration is the winning feature. See our ClickFunnels vs GoHighLevel comparison.
Pros
- Funnels + CRM + email + SMS in one
- Flat fee, unlimited funnels
- Imports ClickFunnels pages
- Leads auto-nurtured
Cons
- Learning curve
- Builder can feel sluggish at times
ClickFunnels
The tool that coined 'sales funnel' - polished templates, proven conversion features (order bumps, one-click upsells), and a huge community and training ecosystem. If funnels are your sole focus and you want the most refined, battle-tested editor, ClickFunnels is excellent. You'll pay more and still need separate tools for a full CRM and advanced email, which is why many migrate to all-in-ones, but for pure funnel-building it remains a benchmark.
Pros
- Best-known funnel templates
- Strong checkout/upsell tools
- Big community & training
Cons
- Pricey
- Not a full CRM
Systeme.io
Astonishing value - a genuinely useful free plan covering funnels, email and even courses, scaling to low-cost paid tiers. Perfect for solopreneurs and side-hustles launching their first funnel without spending a penny. Templates are simpler and there's no native SMS, but the all-in-one breadth on a free plan is unmatched, and the learning curve is gentle - the best way to validate a funnel before investing.
Pros
- Capable free plan
- All-in-one on a budget
- Simple to learn
Cons
- Less polished templates
- Fewer advanced features
Kartra
Kartra bundles funnels, email, memberships, helpdesk and a polished checkout into one platform - a strong all-in-one for course creators and coaches who want a refined selling experience without juggling tools. Its membership and checkout flows are particularly well done. It's pricier at entry and less suited to local-service lead-gen than GoHighLevel, but for selling digital products end-to-end it's excellent.
Pros
- True all-in-one
- Great for memberships/courses
- Solid automation
Cons
- Pricier entry point
- Can feel complex
Leadpages
If you mostly need fast, reliable landing pages and lead-capture rather than full multi-step funnels, Leadpages is affordable, easy and conversion-focused, with a big template library and a track record of solid page speed. It's lighter than a full funnel suite and has no built-in CRM, but for getting high-converting pages live quickly on a budget, it's a great fit.
Pros
- Affordable & easy
- Lots of templates
- Good lead-capture tools
Cons
- Limited full-funnel features
- No built-in CRM
Unbounce
Unbounce focuses on squeezing maximum conversion from each page, with AI optimisation (Smart Traffic that routes visitors to the best-performing variant) and strong A/B testing - a favourite of paid-ads marketers who live and die by conversion rate. It's pricier and focused on landing pages rather than full funnels or CRM, but for high-spend ad campaigns where small conversion gains pay for themselves, it's worth it.
Pros
- AI conversion optimisation
- Powerful A/B testing
- Great for paid traffic
Cons
- Higher price
- Landing pages, not full funnels
All-in-one vs dedicated funnel builder
The core decision is whether your funnel tool should also be your CRM and email platform. A dedicated builder (ClickFunnels, Leadpages, Unbounce) gives you the most polished, conversion-focused pages, but the leads then need to flow into separate CRM and email tools you pay for and maintain. An all-in-one (GoHighLevel, Systeme.io, Kartra) builds the funnel and captures, stores and automatically follows up the lead in the same place - which is usually cheaper and means no leads slip between disconnected tools. For most UK businesses whose goal is converting leads into customers (not just collecting opt-ins), the all-in-one approach wins, which is why GoHighLevel tops our list. If you are a specialist who only needs gorgeous landing pages for paid traffic, a dedicated tool like Unbounce can be the better single-purpose choice.
Tips for higher-converting funnels
Whichever builder you choose, a few fundamentals move the needle far more than the tool itself:
- One page, one goal - remove navigation and distractions; every element should push toward the single call to action.
- Lead with the outcome - your headline should promise the result the visitor wants, not describe your product.
- Follow up fast - connect the funnel to instant email/SMS (native in GoHighLevel) - speed-to-lead dramatically lifts conversion.
- Add an order bump or upsell - the easiest way to raise average order value with no extra traffic.
- Test one thing at a time - A/B test headlines and offers; keep what wins and iterate.
