I used and tested both CrazyEgg and Mouseflow on my SaaS platform and website and in this article, I’ll highlight the differences that stood out to me the most:
CrazyEgg is an excellent tool if you’re looking to optimize user experience with heatmaps and customer surveys. I imagine e-commerce sites would gain the most out of it to improve return visitors’ experience. However, it doesn’t offer any solutions to analyze your customer journey and its session replay feature is painfully slow.
Meanwhile, Mouseflow is built for optimizing conversions by understanding the exact elements users interact with (dynamic heatmaps) and analyzing conversion elements (form analytics). Its strengths are similar to CrazyEgg’s but focused on different use cases, while its weakness is the same: session replay features.
Since both tools lack great session replay for understanding exact user behavior, I included SessionStack in this comparison. It offers detailed error logging, easy-to-use session replay, sitewide user interaction tracking, and real-time co-browsing tools which makes it ideal for product designers, developers, and customer support teams looking to quickly troubleshoot and resolve issues with their SaaS platforms and web apps.
I’ll compare CrazyEgg vs Mouseflow vs SessionStack in six key areas:
I also talk about site loading speed impact and integrations to give you a more complete picture in the overview table below:

In the early-2000s, as internet adoption grew, Asmee Shah and John Butler noticed a very bad trend: most websites offered confusing user experiences. So, in 2006, they started CrazyEgg to provide website owners with actionable insights to improve their online experience.
After pioneering one of the first heatmap technologies, CrazyEgg has added features that help improve your complete online customer experience from browser and mobile experiences to web apps. Tools like the Overlay and Confetti report provide a unique look into how users interact with each element of your webpage. You also have access to unlimited A/B tests and Surveys, letting you experiment with different layouts and optimize your website with direct feedback from your audience. This mix of tools will help you quickly understand what your customers like despite its limiting session recording feature.
E-commerce and utility sites will get the best out of CrazyEgg with direct customer feedback, heatmaps, and A/B tests. That’s reflected in their customer profile which includes companies like CNET, Etsy, and Yahoo.
Mouseflow does this by offering tools like Live Heatmaps, which visualize user interactions on dynamic web page elements like drop-down menus and revolution sliders. You also get access to Form Analytics to track how users find and interact with your web forms. Although its session replay feature is pretty bare-boned, it’s extremely lightweight and doesn’t affect your site speed.
Funnel marketers and landing-page-reliant sites will get the most out of Mouseflow’s dynamic heatmaps and form analytics. That’s why corporate brands like Verizon, Vodafone, Philips, and Etihad use it.
Alexander Zlatkov left his job as a software engineer at Progress in 2016 to create SessionStack: a tool that allowed companies to understand exactly how users interact with their online apps.
SessionStack does this by providing advanced session replay features that offer more value than the others in the market, eventually earning them G2’s “session replay category leader” award in 2023. It essentially lets you join a user’s session in real time by maintaining a latency of under one second. This helped them build a live session support tool called co-browsing. Co-browsing lets you interact with users during a session and take control of their session without installing any third-party software. If you can’t be present in real-time, you can use its advanced error logging and user segmentation tools to identify the most important issues plaguing your website.
Businesses like Kraken.com, Bazaarvoice, and Imagine.ai trust SessionStack because of the tool’s flexibility which caters to most internal teams, including product management, development, and customer support teams.
CrazyEgg is great for user segmentation. Mouseflow is ideal for customer journey analysis. SessionStack makes troubleshooting easier.
Session Replay is an analytics feature that records user sessions on your website, capturing interactions like clicks, mouse movements, scrolls, and page navigation. It’s crucial for understanding user behavior and optimizing the customer experience.
In this section, we will compare the tool’s session replay capabilities on five criteria:
Mouseflow has a simple user interface. I’d say it keeps it too simple by not including an activity or error log.
Instead, it uses different colors to highlight actions (1) like mouse movements, clicks, interactions, etc. Important events are marked using icons (2). For example, ⚠️ for errors and ⚡ for rage clicks, as in the screenshot below. It doesn’t have a console feature with more information about events like SessionStack and CrazyEgg.
CrazyEgg has a very simple design with the video player on the left and the event log on the right. You can jump to an event by simply clicking on its corresponding entry in the event log or on the video player bar. CrazyEgg groups each session by users, making user segmentation and understanding user behavior easier.
But, there are some kinks that I noticed while I was using the tool. The most frustrating one is the long load time (~20 seconds). Also, the console blocks the video player when you open it, restricting your view of the session replay – something you won’t see with SessionStack.
SessionStack’s session replay tool is more user-friendly. It has a video player on the right and an action log (1) on the left-hand side of the screen. As the video plays, the timestamp corresponding to each event is highlighted in the activity log, making it easier to track events as they occur. You can get more information on each event by clicking on the drop-down arrow.
You will also find the console (2) below the video player providing detailed logs on each action, making troubleshooting easier. You can find the exact action you’re looking for using the filters (3).
You’ll notice a “Get Summary” option in the left toolbar of the session recording. Clicking this will trigger the tool’s AI assistant to provide a summary of the entire session recording. This summary consists of three segments:
EDITOR’S NOTE: What is user segmentation?
User segmentation (or ‘audience segmentation’) is the process of categorizing your users based on their demographic, behavior, interactions, and type (new vs returning). Segmenting users is a great way to identify how you can improve your website’s or app’s UI/UX to maximize conversions.
CrazyEgg automatically segments your visitors by assigning each one a unique user ID. Sessions are grouped based on these unique IDs. You can go a step further by filtering your audience according to visitor details, session information, and ad campaign. You can also create up to five custom variables to track trends specific to your business.
Mouseflow provides basic user segmentation filters like device type, session length, location, user action, etc. Although it doesn’t support user profiles, it lets you analyze specific trends by creating custom variables and tags for ad campaigns or events like order amounts, abandoned carts, etc.
SessionStack keeps things very simple. It simplifies user behavior analysis by providing filters covering important segmentation criteria like users, sessions, and events. If you are looking for something different, you can create and save custom user segments that align with your specific needs.
EDITOR’S NOTE: What are live sessions?
Live sessions give you a real-time view of how users interact with your website. It’s a great tool for product, development, and customer support teams looking to resolve customer issues when they are raised.
SessionStack is the only platform offering truly real-time live sessions with a latency of less than one second. Using this, they were able to develop co-browsing – a real-time customer support tool.
Co-browsing lets customer support teams and account managers guide users in real time without installing any plug-ins, software, or add-ons. You get access to three tools in co-browsing mode:
SessionStack protects a user’s privacy by hiding sensitive information like passwords, credit card details, etc. Most of the information is hidden by default. But you can also set your own parameters.
NOTE: Co-browsing is not the same as screen sharing where you can access the user’s computer. Co-browsing only allows access to the shared tab and nothing else. You can read more about co-browsing here.
Winner: SessionStack. Both customer support and product development teams will appreciate its real-time co-browsing feature and faster load times.
CrazyEgg measures the performance of clickable elements, Mouseflow tracks the performance of dynamic elements, while SessionStack helps you identify website issues more easily.
Heatmaps visually represent visitor interactions on your website by highlighting areas that get the most clicks, movements, and scrolls. They can be used to identify the elements users interact with the most, receive the most attention, and frustrate the user.
CrazyEgg has five different heatmaps to understand user interactions.
It offers basic filters like date ranges, device types, etc. You can also compare sessions side-by-side, making it great for evaluating A/B test performances.
Apart from click, scroll, and movement heatmaps, Mouseflow offers dynamic heatmaps to track interaction with dynamic elements like drop-downs, revolution sliders, parallax scrolling, etc. It overlays the data directly on the website to show you exactly how users interact with your website – a feature missing in CrazyEgg.
SessionStack doesn’t offer visual heatmaps. Instead, it provides a sitewide overview of essential user actions and problematic events like:
It simplifies troubleshooting by compiling the most interacted-with elements and frustration signals in one space — cutting down on time spent analyzing the webpage.
Winner: Mouseflow. Along with click, scroll, and mouse movement heatmaps, it offers live heatmaps to help you visualize how users interact with dynamic page elements. You also get access to filters to derive some granular insights.
Mouseflow and SessionStack have funnel analytic tools, while CrazyEgg lets you create and publish surveys.
Customer journey refers to how users navigate your website and interact with content (webpages, blogs, articles, social media posts, etc). You can track the customer journey using funnels (a step-by-step process of how you think visitors interact with your website). Funnels help you understand visitor behavior and let you segment them according to their interactions.
CrazyEgg doesn’t have a funnel analytics tool. But you can use its survey tool to get feedback directly from your visitors, rate their website experience, and gauge your net promoter score (NPS).
With unlimited storage for surveys, you have the freedom to create as many surveys as you like. You get access to two layout types: pop-up and external link. You can also use custom settings and logic to create a dynamic quiz that asks your visitors only relevant questions while minimizing drop-off.
Mouseflow combines historical and real-time data to provide insights on increasing your conversion rate. But, Mouseflow’s funnel analysis tool ignores some important information:
Without this information, you won’t get all the insights you need to make an informed decision.
SessionStack lets you create funnels with unlimited steps. It also provides a more complete solution compared to Mouseflow by including users who complete the conversion step. You can track two important event types: ‘dead clicks’ and ‘rage clicks’. Understanding when and where these events occur can help you resolve them and create a smoother customer journey.
Winner: SessionStack because it lets you create funnels with unlimited steps and addresses the issues with Mouseflow. It’s a great tool for marketing teams looking to optimize their website conversions.
Mouseflow has basic error-logging features, while SessionStack and CrazyEgg have dedicated error-logging pages.
CrazyEgg also has a dedicated error page similar to SessionStack. It automatically detects and lists errors along with important debugging details like full stack trace, visitor information, and application version. Once it’s resolved, you can update its status so your team knows the error has been dealt with. But, unlike SessionStack, CrazyEgg can’t tell you what the exact error is.
SessionStack has a dedicated errors page that provides a comprehensive overview of each error with important debugging information (1). You can also view the related session recording (2) to make troubleshooting easier.
It also highlights errors in the session replay tool (1), making it easier for you to troubleshoot errors. You can use filters to identify specific errors (rage clicks, dead clicks, u-turns, etc.) during a session – something CrazyEgg’s error log doesn’t have. You also access the console feature (2) to get more information about each error.
Winner: SessionStack makes troubleshooting errors faster with its dedicated error page. Development teams will benefit from its great error-tracking and logging features.
Mouseflow and CrazyEgg’s starting plans are cheaper, but SessionStack plans offer the most value for money in the long term.
CrazyEgg offers a 30-day free trial on all its plans with full access to full functionality. Once the trial period ends, you continue with the same paid plan. But, you always have the option to change your plan at any time.
NOTE: CrazyEgg doesn’t offer a monthly subscription plan.
Mouseflow has a 14-day free trial with access to all features and 500 monthly sessions per month for one website. After the trial period, you can opt for the Free Forever plan with access to one heatmap, one funnel, one form, and one feedback survey.
SessionStack gives you access to all features with its free plan. It limits you to 1500 user sessions per month, 3 team seats, and 10 live and co-browsing sessions which is very small-business-friendly.
CrazyEgg’s paid plans start at $29/month. Every plan gives you access to unlimited surveys and responses, websites, and A/B tests but limits you in terms of page views, snapshots, and recordings. But the number of recordings with each plan is the least of the three, starting at 100 recordings per month.
NOTE: Its pricing is based on page views, and not sessions. It only tracks visits to pages you WANT to track, and not total visits to your entire website.
CrazyEgg has based its pricing on websites that focus on conversions. It is perfect for eCommerce and Shopify websites where tracking clicks and interactions on each page provides the most value.

Priority support + Onboarding & training
If your website relies on providing engaging content, you should consider Mouseflow. Its paid plans start at $39/month and give you access to all its features (including forms and feedback surveys). But, it limits how much you can use them.
It does set itself apart from CrazyEgg by allowing unlimited page views. Overall, it’s perfect for review or lifestyle websites that want to provide a great user experience and maximize your ad revenue by keeping them on their site.

SessionStack starts its pricing at $79/month for 10,000 monthly sessions, which is less compared to CrazyEgg and Mouseflow. But it doesn’t place any limits on the number of websites and supports more recordings. It’s ideal for tracking user behavior on web apps and SaaS platforms where you only have a limited number of users. Also, it offers the most value for money with unlimited projects, error tracking, and advanced filters, and user segments.
10,000 sessions/mo + Unlimited projects + Advanced filters and user segments
Launch features + 25,000 sessions/mo + Data export via REST API
Scale features + Unlimited sessions + Dedicated support teams
Verdict: SessionStack is perfect for platforms of all sizes that need an over-the-shoulder view of each individual user. Mouseflow works best for review and lifestyle websites with a large audience. And, CrazyEgg is ideal for e-commerce and Shopify stores tracking conversions.
