Smartlook vs SessionStack: A Definitive Comparison [June 2023]

Smartlook’s heatmaps, funnels, and session replay features work with websites as well as mobile apps but they’re less detailed and give you more of a general overview of user interactions. Nonetheless, its unique funnel anomalies monitoring feature helps with proactively boosting conversion rates.   

But if you want exact user interaction insights, consider SessionStack. It’s equipped with a powerful suite of tools that include pixel-perfect session replays, live co-browsing, sitewide click insights, and error-tracking features. This makes it easy to quickly resolve site errors and address user frustrations — allowing you to consistently improve the customer experience.

Let’s take a closer at the differences between Smartlook vs SessionStack, and see how they stack up in the following areas:

  1. Heatmaps
  2. Customer journey analysis
  3. Session replays (including live sessions, co-browsing, and error tracking) 

Additionally, in the comparison table below, I’ll discuss the site speed impact and integrations for each tool — so you can select the ideal one for your specific requirements.

What is Smartlook?
“A 360-degree view of your customer’s journey” 🌍👀

In 2016, Petr Janošík, Dušan Kmeť, Vladimír Šandera, and Ondřej Machek joined forces to build Smartlook. Their mission: to help businesses gain better insights into customer behavior across their websites and mobile apps.

Fast forward to today, Smartlook has established itself as a prominent player in the behavioral analytics space. With a comprehensive set of tools including session replays, heatmaps, and funnels, Smartlook offers everything you need to gain a deep understanding of user interactions and behavior patterns. It stands out as the only tool that is fully compatible with mobile apps, allowing you to seamlessly analyze user behavior across multiple platforms. Plus, it allows you to set thresholds and track deviations from funnel parameters.

Smartlook’s suite of tools makes it best for users who want to track web analytics as well as mobile analytics and adopt a proactive approach to funnel tracking and optimization. However, it lacks live co-browsing features and extensive error-tracking tools for pinpointing site errors and user frustrations.

What is SessionStack?
“Become the hero of seamless user experience” 🦸‍♂️💫

Alexander Zlatkov, a former software engineer, recognized the need for a tool to understand how users interact with websites and online apps. This led to the creation of SessionStack in 2016.

SessionStack strikes a perfect balance between simplicity and advanced session replay features, propelling it to the top position of G2’s “Session Replay” category for 2023. It perfectly captures and stores every user session and also registers online users — allowing you to watch their live sessions with super low latency (<1 second). You can switch on the co-browsing mode during live sessions to interact directly with a user’s screen. When you combine these features with SessionStack’s dev console, dedicated error-tracking page, and sitewide click maps, you have a powerful toolkit that ensures no site error or user frustration slips through the cracks.

SessionStack caters to the unique needs of various teams, including product, customer support, developers, and engineering. By providing deep insights into user interactions, facilitating quick issue resolution, and enabling real-time support, it guarantees that websites and online apps consistently deliver an optimal user experience.

Smartlook vs SessionStack: Session Replay

Smartlook only has core replay features and basic segmentation options, while SessionStack takes the cake with live sessions, co-browsing, and dedicated error-tracking

Smartlook SessionStack
⭐⭐⭐ ⭐⭐⭐⭐⭐

Session Replay is a feature that records and plays back user interactions on your website. It captures everything from mouse movements and clicks to scrolling and pageviews. In this section, we’ll dive into each tool’s session replay capabilities and compare them in four key areas.

  1. UI design,
  2. User segmentation,
  3. Live sessions & Co-browsing,
  4. Error logs.

Smartlook vs SessionStack: Session Replay UI

Smartlook feels quite busy, and SessionStack simplifies and speeds up your workflow.

Out of the three tools, SessionStack’s interface is the easiest to navigate. The simple two-column layout and bold icons provide a clear separation between the content area and navigation menu, and make it easy to quickly find any feature you’re looking for. 

As a result, SessionStack has the lowest learning curve for new users, allowing them to quickly become familiar with the platform and start leveraging its insights.

Additionally, SessionStack’s session replay syncs perfectly with the action log (on the left). It also features a well-structured two-column layout that makes navigation feel more intuitive. This speeds up your workflow because you can quickly jump to specific user actions and resolve issues in no time.

Smartlook’s interface has a modern but monotone design with a two-column layout which makes navigation that can feel a bit overwhelming for first-time users to navigate and locate specific features quickly. 

Smartlook vs SessionStack: User Segmentation

Each tool lets you segment users but Smartlook stands out with its extensive date filter options.

Watching every single session replay isn’t practical in most cases. So, by segmenting users based on their actions and other data, you can derive insights from a larger database of site interactions, without having to look at each separate user recording.

Creating user segments is a simple and intuitive process across all three tools. In addition, they cover most of the common filter options you’ll need to build these segments — for example, user ID, device, browser, operating system, visited URL, session duration, and referrer URL. Since the differences in the tools’ filter options are minimal, picking one over the other is a matter of personal preference.

For example, SessionStack is the only tool with filters for browser version, pricing plan purchased, active time, and dead clicks. 

Then there’s Smartlook with unique filters like landing URL, exit URL, number of pages per visit, and the total number of visits. In addition, it has the most extensive date filter (i.e. the pre-made date ranges like last 7 days, last 30 days, etc., and setting custom date ranges with specific time stamps). 

SessionStack vs Smartlook: Live Sessions & Co-browsing

SessionStack stands out from the pack because of its live sessions and co-browsing features.

SessionStack has a dedicated page where you can see all the online users on your site at any given time. From here, you can join their live sessions at super low latency (less than 1 second), which essentially lets you track user interactions in real time. Additionally, you can also see if the user is no longer active on your site or has gone offline. 

But that’s not all… SessionStack builds on its low-latency live feature with co-browsing — meaning not only do you get to see real-time interactions on your site, but you can directly interact with users via their screen. And guess what? You don’t need to download any external software to make this work. 

NOTE: Co-browsing is not the same as screen sharing — it doesn’t require any third-party installation to work and it only gives you access to the single browser tab where the user has opened your site. You can learn more about this in our article on screen sharing vs co-browsing.

When you activate the co-browsing mode during a live session, you get access to the following tools:

  • A pointer: Highlight screen elements to draw a user’s attention to it.
  • A pen: Draw on a user’s screen to annotate or illustrate a point. 

Control takeover: Gain user consent to carry out actions on their behalf.

The combination of live and co-browsing features is perfect for product managers and customer support teams who want to offer real-time, personalized support to users — quickly resolving user issues and improving their experience.

SessionStack vs Smartlook: Error Logs

Smartlook has basic dev tools in session replays, SessionStack takes it a step further with a dedicated error-tracking page.

Smartlook includes dev tools features in their session replays, which log all errors recorded during a session. However, finding the errors isn’t straightforward — imagine how tedious it would be to have to watch individual session replays to find them. 

This is why SessionStack has a dedicated error-tracking page for compiling sitewide errors. And the best part? Each error recorded on this page directly links to the specific timestamp of the session replay where it occurred — no time wasted searching for it. 

So if you choose to watch a session replay, it plays automatically and stops right at the mark where the error occurred. This helps you better understand the specific user action that led to the error. From here, you can open the console to get a better understanding of the error details. 

Winner: SessionStack. It has everything for everyone. For example, product and customer support teams would love its pixel-perfect session replays in addition to the live and co-browsing features. Technical teams like developers and engineers will appreciate its dev console and error tracking page.

SessionStack vs Smartlook: Heatmaps

Smartlook gathers page-specific insights, while SessionStack gives you a comprehensive overview of sitewide performance

SmartlookSessionStack
⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐

Heatmaps are a visual and quantitative representation of general user behavior on your site. They can be grouped under three main categories: mouse maps show cursor movement patterns, scroll maps show scrolling behavior, and click maps show areas that attract the most clicks.

Smartlook lets you capture clicks, moves, and scrolls for static page elements.

Smartlook enables you to view all the heatmap types (click, scroll, and move maps), and filter the heatmaps by device type (desktop, tablet, and mobile) and users (all, new, and returning).

While visual heatmaps are great tools for getting a feel of aggregate user behavior, keep in mind that their accuracy is greatly impacted if you’re dealing with sampled data or when analyzing low-traffic websites.

SessionStack’s unique approach to action maps surfaces site-wide elements that get the most attention and cause the most frustration.

Unlike Smartlook, SessionStack doesn’t have visual heatmaps and, as a result, sidesteps the limitations that come with them. Instead, it scans your entire site and highlights the top elements (static and dynamic) that are either performing well or need attention — and groups them into three categories:

  1. Most clicked elements: Elements with the most clicks.
  2. Dead clicks: “Un-clickable” elements that were at least clicked once.
  3. Rage clicks: Elements that received multiple clicks at a go because they didn’t produce an outcome that users expected. 

Similar to Smartlook, you can filter these elements to display more contextual insights using SessionStack’s extensive filter options.

This feature (+ the error tracking page + dev console) makes SessionStack a powerful tool for a wide range of tech teams (developers, engineers, etc.) to quickly identify site errors and user frustrations — so they can prioritize their optimization efforts and achieve the best user experience. 

Verdict: Smartlook is best for analyzing high-traffic sites with little to no dynamic elements and SessionStack’s unique approach is perfect for all sites that benefit from quickly resolving user frustrations and proactively maintaining an optimal user experience.

Smartlook vs SessionStack: Customer Journey Analysis

Smartlook lets you monitor funnel anomalies but SessionStack’s funnel features give you the most comprehensive insights.

Smartlook SessionStack
⭐⭐⭐⭐⭐ ⭐⭐⭐⭐

A customer’s journey is the step-by-step path they take while moving through your site (eg. URL visits, clicks on specific elements, etc.)  — and the funnel feature helps you track, visualize, and analyze those journeys.

SessionStack’s insights cover a wide range of scenarios including form analysis and user frustrations.

SessionStack lets you add an unlimited number of steps to your funnel. For each step, you can specify any of these five event types: 

  1. Visited URL,
  2. Clicked element,
  3. User input,
  4. Dead click, and
  5. Rage click.

These event types give you the flexibility to monitor a wide range of scenarios from cart abandonment and form analysis to friction points and user frustrations.

Another recent addition is the ability to display funnels of different user segments. This effectively lets you A/B test how different user groups behave in your funnels based on their segmentation metrics as shown in the screenshot below.

SessionStack also covers key funnel analysis features — these include conversion and drop-off rates, and their linked session recordings to dive deeper into the “why” behind a user’s conversion or drop-off. This is very helpful for an in-depth understanding of user behavior and fine-tuning your conversion funnels to boost conversion rates.

Smartlook has the key funnel features in SessionnStack however, setting up events is not straightforward and may be confusing, especially for new users.

However, it has a unique “anomalies monitoring” feature that notifies you whenever anomalies are detected in your funnels — for example, if there is a sudden spike in conversions or drop-off rates along your funnel. 

While this proactive approach allows you to closely monitor and optimize the user experience, setting it up requires some level of technical expertise.

Verdict: SessionStack excels at creating detailed funnels and identifying user struggles and Smartlook helps to stay on top of your user experience with a more proactive approach to funnel monitoring and analysis.
