Also considered, not yet listed

  • Justuno: A list-growth tool for ecommerce brands, priced by visitors, with no free plan and a done-for-you plan. It fits stores more than the self-serve teams Claspo serves, and we haven't read every one of its reviews yet.
  • 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.
  • Claspo's own paid plans: If the free plan is what you've outgrown, its paid plans keep every feature and start at $39 / mo for 50,000 pageviews, with a 14-day trial once the free limit is reached.

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 Claspo 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; Claspo's on 23 Sep 2026. Claspo's pricing page opens on annual billing, so its monthly prices were read with the switch set to monthly. 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. G2 labels every Claspo review organic. Sleeknote has too few G2 reviews to read alone, so we also read its Capterra and Trustpilot reviews. 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 Claspo alternative?
The best Claspo 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 leads going to Zapier or Make, Popupsmart. For the same every-feature model with a bigger free plan, OptiMonk. For popups and email from one company, Poptin, or Privy for an online store that wants SMS too. For a Shopify store that wants AI or a team to run its popups, Alia. For campaigns a strategist builds for you, Wisepops. For forms inside your pages, OptinMonster. For a WordPress site on a budget, Popup Maker's free plugin. For many websites with phone support, Sleeknote.
Is there a free alternative to Claspo?
Claspo's own free plan covers 3,000 pageviews a month with every feature. OptiMonk (10,000 pageviews), Popupsmart (5,000 pageviews) and Poptin (1,000 visitors) also start free, and Popup Maker's core plugin is free with no traffic limit, on WordPress only. Privy, Alia, Wisepops, OptinMonster and Sleeknote don't: they offer a trial or a money-back guarantee instead.
Is Claspo cheaper than Popupsmart?
Claspo is cheaper than Popupsmart only on annual billing. The monthly list prices are the same at every tier, $39 a month for 50,000 pageviews on both, and level above that. Claspo takes 25% off for annual billing, which puts it about 10% below Popupsmart over a year. What differs is what the price buys: Claspo puts every feature on every plan, and Popupsmart covers 3 websites on its 50,000-pageview plan and sends leads to Zapier and Make. The full price table is in Popupsmart vs Claspo.
Can I move my Claspo popups to another tool?
Claspo popups don't carry over to any of these tools, so each campaign is rebuilt. If you move to Popupsmart, our team rebuilds your Claspo 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. Your email list stays in your email platform, so connecting the new tool to it keeps new leads going to the same place.
Does Claspo work with Zapier?
Claspo's integrations page lists 13 native email and CRM tools and webhooks; Zapier and Make aren't on it. Popupsmart connects to both on every plan, and Sleeknote lists Zapier among its direct integrations.
Does Claspo have an AI agent?
Claspo's AI rewrites copy, translates widgets and drafts A/B test variants. In a beta for online stores, three AI agents, working with Claspo specialists, propose campaigns, build them and test them, and you approve each launch. Its pages list no MCP server or CLI for your own agent. In Popupsmart, the AI agent builds and publishes a whole campaign from a chat, and the MCP server and CLI let your own agent do everything the app does, on every plan, the free one included.
Why do people look for Claspo alternatives?
In our reading of every Claspo review on G2, most reviewers name nothing they dislike. The complaints that do come up are settings that are hard to find at first, missing features, integrations that take setup and a plan structure that confuses. Its reviewers praise its ease of use above everything else, and G2 labels every one of its reviews organic. Other reasons come from its own pages: no Zapier or Make, and one website on the free plan.
