Frequently asked questions

What is the best popup tool for SaaS?

For lightweight popups — website lead capture plus in-app announcements, NPS, polls, and upgrade nudges — TinyPopups is the best popup tool for most small SaaS teams. It installs with one script tag, starts at $19/mo, and does not require a CRM or CDP.

Are website popup builders the same as in-app popup tools?

No. A website popup targets anonymous visitors for lead capture. An in-app popup tool targets logged-in users by plan, event, or page. TinyPopups does both from one script.
