Claspo takes 25% off for annual billing against Popupsmart's smaller reduction, which puts it about 10% cheaper over a year. These are the prices each company's pricing page showed on 23 Sep 2026.
Which free plan is better, Popupsmart's or Claspo's?
Whether Popupsmart's or Claspo's free plan is better depends on what runs out first. Claspo's free plan has every feature, A/B testing included, with unlimited widgets and team members, and allows 3,000 pageviews a month. Popupsmart's allows 5,000 pageviews a month and every campaign type, with one popup live at a time. If traffic is your limit, Popupsmart's gets you further; if you want several popups live or A/B testing before you pay, Claspo's does.
Does Claspo have a free plan?
Yes, Claspo has a free plan with no time limit. It covers up to 3,000 pageviews a month on one website, with every feature, unlimited widgets and team members, and a Powered by Claspo badge. Once the limit is reached, Claspo offers a 14-day trial of its paid plan.
Does Claspo work with Zapier?
Claspo's integrations page lists 13 native email and CRM connections and webhooks; Zapier and Make are not on it. Popupsmart connects to both, and to 17 other destinations.
Which integrations does each tool have?
Popupsmart and Claspo both connect natively to Mailchimp, Klaviyo, HubSpot, Salesforce, ActiveCampaign, MailerLite, SendGrid, Brevo, Google Analytics and webhooks. Only Popupsmart lists Zapier, Make, Customer.io, Drip, EmailOctopus, Ontraport, Sendy, Sendloop and Meta Pixel. Only Claspo lists Pipedrive, GetResponse, Omnisend, Beehiiv and Userlist; with Popupsmart those go through Zapier, Make or a webhook.
Do both tools have A/B testing?
Yes, Popupsmart and Claspo both have A/B testing. Claspo includes A/B testing on every plan, the free one too, with confidence scores and AI-drafted variants. Popupsmart includes it from the Advanced plan, $69 a month for 100,000 pageviews.
Do both tools have AI features?
Yes, Popupsmart and Claspo both have AI features. Claspo's AI rewrites copy, translates widgets and drafts A/B test variants. Claspo is also testing an AI CRO service in beta for online stores: three AI agents, working with Claspo specialists during the beta, propose campaigns, build them with their targeting and run their A/B tests, and you approve each launch. Popupsmart's AI popup builder drafts a campaign, and Smart Mode, on paid plans, picks the audience after at least a month of manual targeting.
Can my own AI agent build campaigns in Popupsmart or Claspo?
In Popupsmart, yes. Its MCP server and CLI give an AI agent everything the app does: it generates the popup from a template, sets the targeting and triggers, connects your email tool and publishes, in under a minute, on every plan, the free one included. Inside the app, the Popupsmart AI agent does the same from a chat, on every plan. Claspo's pages list no MCP server or CLI. Its AI agents work inside Claspo, among them the beta CRO service for online stores, where they work with Claspo's specialists.
Which one has more templates?
Claspo, with more than 1,000 on every plan. Popupsmart lists 500+. Most teams adapt a handful of layouts rather than browse a whole catalogue, so check that the campaign types you need are covered before counting.
How do G2 reviewers rate Popupsmart and Claspo?
On 23 Sep 2026, Claspo was rated 4.9 from 81 reviews and Popupsmart 4.5 from 141. Reviewers of both most often praise how easy the tool is to use.

Can I switch from Claspo to Popupsmart?
Yes, you can switch from Claspo to Popupsmart. Popupsmart installs with one embed code on any website, or through its Shopify app or WordPress plugin. Rebuild your live campaign on the free plan first, and upgrade once it converts.
Which one should I choose?
Choose Claspo if price, every feature on every plan or the size of the template library decides it. Choose Popupsmart if your leads go to a tool only Popupsmart connects to, such as Customer.io, Drip, Ontraport, Sendy or anything Zapier or Make reaches, if you want 5,000 free pageviews while you test, if you run click-to-call campaigns, or if you want your own AI agent to build and publish campaigns over MCP or the CLI.
