If you are comparing session recording tools, the real question is not which has the prettiest replay player. It is which one will actually surface a fixable problem on your site before your budget or your patience runs out. Hotjar, Microsoft Clarity, and FullStory all record sessions and draw heatmaps, but they sit at very different points on price, depth, and who they are built for. This is a practical breakdown of the three, with a session recording tool verdict by team size at the end. Pricing in this space changes often, so confirm current numbers on each vendor’s page before you buy.
The short version
Clarity is free and surprisingly capable. Hotjar is the friendliest for marketers who want recordings, surveys, and feedback in one place, though it is now part of Contentsquare and its plans have shifted over time. FullStory is the heavyweight: deep behavioral data, strong search, and an enterprise sales process to match. If you only read one paragraph, read this one: start with Clarity, graduate to Hotjar if you need feedback tooling, and look at FullStory only when you have a product or CX team that will live in the data.
1. Microsoft Clarity: the free baseline
Clarity gives you session recordings, heatmaps, rage-click and dead-click detection, and basic funnels with no traffic cap and no price tag. That is the headline, and it genuinely holds up. Microsoft funds it as part of its wider ecosystem, so the tradeoff is less about cost and more about depth: the filtering is simpler, the survey and feedback features are limited, and you will not find the same polish in reporting that paid tools offer.
Best for: Small teams, early-stage B2B sites, and anyone who needs to prove the value of session replay before asking for budget.
2. Hotjar: the marketer-friendly middle
Hotjar built its reputation on being easy to set up and easy to explain to a non-technical stakeholder. Recordings, heatmaps, on-site surveys, and feedback widgets live in one interface. It has a free tier with a small daily session allowance, and paid plans scale by session volume. Since the Contentsquare acquisition, pricing and packaging have moved around, so check the current plan structure rather than trusting old comparison tables. Where Hotjar earns its price over Clarity is the survey and feedback layer, which turns “users dropped off here” into “users told us why.”
If you are also tuning pages through experiments, pair it with the testing tools in our A/B testing and CRO tools roundup, since recordings tell you what to test and experiments tell you whether the fix worked.
Best for: Marketing teams and agencies that want qualitative feedback alongside replays without involving engineering.
3. FullStory: the enterprise-grade option
FullStory captures a much richer picture of behavior. Its search lets you find sessions by what users did, such as everyone who hit an error and then abandoned checkout, which is far more useful than scrubbing through random recordings. It also leans into frustration signals, journey analysis, and integrations aimed at product and support teams. The catch is cost and commitment: paid plans are typically quote-based, and the tool rewards teams with someone who owns the analysis. A small marketing team will likely pay for depth it never uses.
Best for: Product-led companies, ecommerce at scale, and CX or engineering teams that need to debug real user friction.
Where the three differ in practice
On pricing, Clarity is free, Hotjar is self-serve and usage-tiered, and FullStory is usually negotiated. On privacy and compliance, all three offer masking of sensitive fields, but you should still audit what gets captured, especially on forms, and confirm consent handling for EU visitors. On data depth, FullStory leads, Hotjar is adequate for most marketing questions, and Clarity covers the basics well. On feedback tooling, Hotjar clearly wins. On performance impact, any tracking script adds weight, so test your page speed before and after, ideally alongside the checks in our guide to heatmap and session recording tools for B2B websites.
Verdict by team size
Solo founder or team of 1 to 5: Use Clarity. It costs nothing, and the main risk is spending money before you have a habit of watching recordings.
Marketing team of 5 to 30: Run Clarity first, then add Hotjar if you want surveys and feedback widgets tied to the same pages. Do not pay for both to do the same job.
Product or ecommerce team with dedicated analysts: Evaluate FullStory with a real trial against a real problem, like a checkout drop-off. If you cannot name the question you want answered, you are not ready to pay for it.
Setup, privacy, and the gotchas nobody mentions
All three install with a script tag or a tag manager, and a basic setup takes under an hour. The slower part is governance. Decide up front which pages and fields get masked, who is allowed to watch recordings, and how long you keep them. Login pages, payment forms, and anything containing personal data should be excluded by default. Also watch for sampling: some plans record only a slice of sessions, which can hide the rare, expensive failures you most want to see. Finally, recordings are easy to over-trust. Ten sessions show you a pattern, not a statistic, so use replays to form a hypothesis and your analytics or an experiment to confirm it.
How to pick a session recording tool without regret
Set a single success test before you install anything: find one concrete UX issue on a high-value page within two weeks. Watch ten recordings of visitors who abandoned a pricing or demo form, note what repeats, ship one fix, and measure the result. If a free tool gets you there, you have your answer. If you keep wishing you could filter by behavior or collect survey answers, that is the signal to move up a tier. The best session recording tool is the one your team will actually open every week.
