The verdict
For a founder or small B2B team who wants to see what is happening on the site without a budget conversation, start with Microsoft Clarity. It is free forever with no usage limits, installs alongside GA4 and Google Tag Manager, and surfaces the signals that matter , rage clicks, dead clicks, scroll depth , with zero setup tax.
Reach for Contentsquare when watching sessions stops being enough and you need to quantify the friction: funnel and journey analysis, product analytics, and custom dashboards that tie behaviour back to conversion. Contentsquare also offers a free tier, so you can trial the depth before its Growth plan (from 40 USD/mo) or sales-led Pro and Enterprise tiers come into play.
The honest read: most lean teams over-buy here. Clarity covers the 80% case at no cost. Move to Contentsquare when you have a specific analytical question Clarity cannot answer , not before.
