Also considered, not yet listed

  • Justuno: A list-growth tool for ecommerce brands, priced by visitors, with no free plan. Its pricing page shows two plans only, so we can't say yet how it prices many websites, and we haven't read every one of its reviews.
  • Hello Bar and ConvertFlow: Not listed: we haven't read every one of their reviews yet, so there's no reading to set beside the others.
  • Klaviyo forms and Shopify Forms: Signup forms built into an email platform and into Shopify. They're free with those platforms but aren't popup builders, so we haven't compared them here.
  • Sleeknote's Gamification add-on: If games are what you're missing, Sleeknote adds Spin to Win, Scratch to Win, Learn to Earn, a Seasonal Calendar and quizzes for $26 a month more at the entry tier.

How we made this list

We make Popupsmart, one of the tools on this list, and list it first. The picks and the entries say where each other tool fits better, and where Sleeknote itself is the better choice.

Prices and free plans come from each vendor's own pricing page, read on the dates shown beside each tool; Sleeknote's on 27 Sep 2026, from a US location in US dollars. Sleeknote bills by monthly visitors and prints about 3 pageviews per visitor beside its plans; where we compare its price with Popupsmart's, we use that figure. Where a vendor bills visitors or impressions rather than pageviews, the table says so and converts nothing. Popupsmart's figures come from our pricing page.

Reviews: an AI assistant read every G2 review of each product and sorted what the reviewers praise and criticise into themes; the counts are reviews per theme, out of all the reviews read. No person has checked every tag. Sleeknote has only 6 reviews on G2, too few to count themes, so we also read every Sleeknote review on Capterra (13), Trustpilot (16) and the Shopify App Store (4), the Danish ones in Danish. Each site's figures stay under its own name and are never added together. Alia has no G2 page, so its entry gives its Shopify App Store rating and no theme counts. Review sites mix organic reviews with ones the vendor invited; each product's reviews say which.

The screenshots are ours, of each vendor's home page while logged out, and each caption gives the day it was taken.

Frequently asked questions

What is the best Sleeknote alternative?
The best Sleeknote alternative depends on why you're leaving. If your team has no developer and wants campaigns live the same day, built by hand or by the Popupsmart AI agent, with a free plan to start, Popupsmart. For every feature on every plan with a free plan, OptiMonk, or Claspo if you want games included. For popups with email and SMS in one app, Privy. For a Shopify store that wants AI or a team to run its popups, Alia. For campaigns a strategist builds for you, Wisepops. For popups and email from one company on a small budget, Poptin. For forms inside your pages and agency tools, OptinMonster. For many WordPress sites priced by site, Popup Maker.
Is there a free alternative to Sleeknote?
Sleeknote has no free plan, only a 14-day trial. OptiMonk (10,000 pageviews), Popupsmart (5,000 pageviews), Claspo (3,000 pageviews) and Poptin (1,000 visitors) start free, and Popup Maker's core plugin is free with no traffic limit, on WordPress only. Privy, Alia, Wisepops and OptinMonster don't: they offer a trial or a money-back guarantee instead.
Is Sleeknote cheaper than Popupsmart?
At most traffic levels, Sleeknote is not cheaper than Popupsmart. At the 3 pageviews per visitor Sleeknote prints beside its own prices, Popupsmart costs less at four of the seven traffic levels compared in Popupsmart vs Sleeknote, the same at one and more at two. Below 50,000 pageviews, Popupsmart starts free and Sleeknote at $69 / mo. What the price buys differs: every Sleeknote plan has A/B testing, analytics and unlimited websites, and every Popupsmart plan has gamified popups, which Sleeknote sells as an add-on.
Can I move my Sleeknote popups to another tool?
Sleeknote popups don't carry over to any of these tools, so each campaign is rebuilt. If you move to Popupsmart, our team rebuilds your Sleeknote campaigns for free and adds 2 hours of consultancy on them (a $300 value). With the other tools you rebuild each one yourself, from a template. Download your leads from Sleeknote as a CSV first, since its help center says it keeps them for three months, and connect the new tool to your email platform so new leads go to the same list.
Which Sleeknote alternatives include gamified popups?
Popupsmart puts spin-to-win, lottery ball and surprise box popups on every plan, the free one included, and Claspo includes its eight gamification mechanics on every plan too. Sleeknote sells Spin to Win, Scratch to Win, Learn to Earn, a Seasonal Calendar and quizzes as an add-on.
Why do people look for Sleeknote alternatives?
Sleeknote has few public reviews, so no reading can rank its complaints. The ones that recur are missing features and a price that climbs for smaller sites, on Capterra, and audience settings that took trial and error, on G2. Its Trustpilot reviewers praise its support most, and its Capterra reviewers its ease of use. Other reasons come from its own pages: no free plan, and games cost extra.
