CrazyEgg vs SessionStack: A Definitive Comparison [June 2023]

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.

SessionStack 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 SessionStack in five key areas:

  1. Heatmaps
  2. Co-browsing
  3. Session replay
  4. Customer journey analysis
  5. Error logs

I also talk about site loading speed impact and integrations to give you a more complete picture in the overview table below:

What is CrazyEgg?
“Speak to your customers directly” 🧑‍🏫

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.

What is SessionStack?
Create the perfect customer experience” ⭐💻⭐

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, Bazaarvoice, and trust SessionStack because of the tool’s flexibility which caters to most internal teams, including product management, development, and customer support teams.

CrazyEgg vs SessionStack: Session Replay

CrazyEgg is great for user segmentation while SessionStack makes troubleshooting easier

CrazyEgg SessionStack
⭐⭐⭐ ⭐⭐⭐⭐⭐

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:

  1. UI/UX design
  2. User segmentation
  3. Live sessions
  4. Co-browsing

UI/UX design
SessionStack is very user-friendly while CrazyEgg has long load times and a clunky UI.

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).

User Segmentation
Both support user segmentation. SessionStack offers the most relevant options while CrazyEgg segments users automatically.

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. 

Meanwhile, 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. 

Live Sessions & Co-Browsing
CrazyEgg doesn’t offer live sessions, while SessionStack does and provides a real-time support tool called co-browsing.

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:

  • A pointer to highlight elements on the screen without interacting with the page elements.
  • A pen to add annotations on your user’s screen.
  • Control takeover which gives you permission to perform actions on the user’s behalf from your browser.

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 vs SessionStack: Heatmaps   

CrazyEgg measures the performance of clickable elements, while SessionStack helps you identify website issues more easily.

CrazyEgg SessionStack
⭐⭐⭐⭐⭐ ⭐⭐⭐

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 lets you deep-dive into each page element.

CrazyEgg has five different heatmaps to understand user interactions.

  1. Heatmap reports are simple ‘click’ heatmaps to see which parts of the website are getting the most attention.
  2. Scrollmap reports to illustrate how far visitors scroll on your most important web pages.
  3. List report displays every interaction in a tabulated format.
  4. Overlay reports measure the performance of your clickable elements individually.
  5. Confetti map is just a more detailed heatmap report with metrics to assess on-page behavior.

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. 

SessionStack offers insights into the most relevant user interactions.

SessionStack doesn’t offer visual heatmaps. Instead, it provides a sitewide overview of essential user actions and problematic events like:

  • Most clicked elements (1)
  • Elements with the most ‘dead clicks’ (2)
  • Elements with the most ‘rage clicks’ (3)

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: CrazyEgg. Along with click, scroll, and mouse movement heatmaps, it offers more details with list and confetti reports. You also get access to side-by-side session comparisons, which let’s you “AB test” with session replays.

CrazyEgg vs SessionStack: Customer Journey Analysis

SessionStack has funnel analytic tools, while CrazyEgg lets you create and publish surveys.

CrazyEgg SessionStack
⭐⭐ ⭐⭐⭐⭐⭐

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 lets you create unlimited surveys to understand your customer preferences.

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.

SessionStack tracks important event types for a flawless customer journey.

SessionStack lets you create funnels with unlimited steps. 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. It’s a great tool for marketing teams looking to optimize their website conversions.

CrazyEgg vs SessionStack: Error Logs

SessionStack and CrazyEgg have dedicated error-logging pages but SessionStack provides more details for faster troubleshooting

CrazyEgg SessionStack
⭐⭐⭐⭐ ⭐⭐⭐⭐⭐

CrazyEgg doesn’t tell you what the error is.

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’s console makes troubleshooting faster with detailed error information.

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.
