LogRocket vs FullStory: A Definitive Comparison (June 2023)

LogRocket and FullStory are two well-established behavioral analytics tools on the market. Here’s what I learned after using both to analyze visitor interactions:

FullStory is a general-purpose behavioral analytics tool with a focus on providing insights into specific user segments with heatmaps and funnels. However, developers, project managers, and support teams will find that it lacks adequate error tracking and session replay features.

On the other hand, LogRocket’s unique approach to funnels and advanced error tracking make it great for developers that need a powerful console tool and for marketers that need more granular insights into their funnels. However, it’s not optimal if you want to understand how users interact with online platforms due to its limited session replay features.

SessionStack fills in this gap perfectly, which is why I’ve included it in this comparison. With its pixel-perfect session replay, practical error logs, sitewide click trends, and real-time co-browsing tools it enables UX designers, product managers, and customer support teams to get impeccable insights into how users are using SaaS platforms and web apps, letting them quickly identify and resolve frustrations and improve overall user experience.

In this article, I’ll dive deeper into the comparison—LogRocket vs FullStory vs SessionStack—by reviewing the following key areas:

  1. Heatmaps
  2. Error tracking
  3. Customer journey analysis
  4. Session replay & co-browsing

What is LogRocket?
“See the bigger picture through data visualization” 🧐🖼️

Matthew Arbesfeld and Ben Edelstein founded LogRocket in 2016 to help web app owners stay competitive by enhancing their user experience.

Today, LogRocket is equipped with all key web analytics tools. As for user experience analytics, they offer three types of visual heatmaps for viewing aggregate user behavior: click maps, scroll maps, and hover maps. It also has a unique path analysis view for conversion graphs — which doesn’t only show you where users are dropping off in your funnel, but also the alternate routes they’re taking. Out of the three tools, LogRocket has the best performance monitoring and error-tracking features, from a dedicated errors page that lets you view and triage issues, to an advanced dev console for displaying network logs, Javascript errors, DOM elements, and site performance.

LogRocket’s features make it best for understanding general user flows, optimizing retention and conversion rates, and efficiently resolving errors that arise on your site or app. But due to its limited replay features, you can’t view live sessions of users and provide them with real-time support when needed. 

What is FullStory?
“An inside view of your customer’s journey” 🔍🎭

Scott Voigt, a former Google engineer, and his two ex-colleagues founded FullStory in 2014. While working on their own app, the trio needed a tool to track how customers were using it, which led to the creation of FullStory. 

Since then, FullStory has become a major player in the digital experience space. It has the best user segmentation features which makes it easy to define specific customer personas and understand how they interact with your website. FullStory provides a suite of tools – from visual heatmaps to session replays and conversion funnels. The platform records and indexes every user session and interaction, and even enables live viewing. In addition, its funnel conversion view lets you gain deeper insights into user flows by letting you compare each conversion funnel across multiple user segments. 

Although FullStory is a versatile platform, the lack of co-browsing features makes it difficult to identify user frustrations and provide the necessary support. However, if you’re looking for a tool that lets you gain a better understanding of specific user behaviors, then FullStory is your best choice. 

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

During his time as a software engineer at Progress, Alexander Zlatkov noticed a lack of tools to understand user interactions with websites and online apps. He founded SessionStack in 2016 to create a solution that addressed this gap in the market.

SessionStack’s advanced session replay features have earned it G2’s title “session replay category leader” for 2023. It supports live sessions and lets you interact with online users in real time via the co-browsing mode at a remarkably low latency of less than 1 second. It also has a dedicated error tracking tool, which is perfectly synced with session replays for quickly identifying and resolving issues. With its dashboard metrics and user segmentation features, you get a bird’s eye view of the most common user frustrations on your site, enabling you to make targeted and data-driven improvements.

SessionStack’s robust session replay features make it perfect for a wide range of teams (product management, development, customer support, etc.) who are focused on quickly identifying and resolving errors, and user frustrations, and improving the overall experience customers have on their site and web apps.

LogRocket vs FullStory vs SessionStack: Session Replay

LogRocket and FullStory are similar and stand out with extensive user segmentation options, while SessionStack shines with its live co-browsing and error-logging features.

LogRocket FullStory SessionStack
⭐⭐⭐ ⭐⭐⭐⭐ ⭐⭐⭐⭐⭐

Session Replay is a “video-like” playback of user interactions (e.g. page visits, window resizing, cursor movements, clicks, etc.) on your website. In this section, we’ll compare the following areas of each tool’s session replay feature:

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

Session Replay’s UI design
FullStory’s UI feels complex and overwhelming, LogRocket’s is similar but more intuitive, while SessionStack’s is simple and easy to navigate.

SessionStack’s interface is designed with the user in mind, featuring a simple two-column layout, bold icons, and large buttons that make navigation intuitive and effortless.

The synchronized action log on the left allows you to easily follow and pinpoint specific user actions during session replays. This design ensures workflows remain fast and efficient, even for long sessions — you can quickly jump to specific user actions, and find issues in little to no time.
FullStory has a very modern and polished interface, however, it’s jam-packed with features that make it feel cluttered and clunky.

Meanwhile, LogRocket‘s interface is very similar to FullStory’s but it lacks the helpful commenting and navigation features that make it easy to highlight specific areas in session replays and switch between them seamlessly.

There’s also no option for slowing down a replay which can make it difficult to analyze complex user interactions at your own pace.

AI-Augmented Session Replays
SessionStack’s AI-powered session replays offer concise session summaries and actionable optimization insights.

On the left-hand toolbar of SessionStack’s session replay tool, you’ll spot a “Get Summary” button. Using this feature prompts the AI to curate a summary of the session recording. This summary is written in three parts:

  • Session description: A short recap of the user’s activities throughout the session.
  • Noteworthy events: A ten-point bullet list of the most important events during the session.
  • Optimization strategies: Proposals for fine-tuning the user journey based on the events that happened during the session.

User Segmentation
All three tools let you create segments with user, session, and event filters but LogRocket and FullStory are the most equipped with customization options.

User segmentation (aka ‘audience segmentation’) is a feature that lets you categorize your site users based on various criteria including their demographics, hardware and software, and the actions they take on your site. It’s an essential tool for gaining a deeper understanding of how users interact with your website.

With SessionStack, creating user segments is a breeze for both technical and non-technical users. You can easily build and save multiple customer segments by setting up specific user, session, and event filters to gain a comprehensive understanding of user behavior and engagement on your app.

Compared to SessionStack, LogRocket and FullStory have more extensive options for nuanced customer segments. The only difference between them is that LogRocket has a “Recents” feature which makes it easier and faster to re-use your most common segmentation filters.

Live Sessions

FullStory has live session viewing, SessionStack does it better with very minimal delays, while LogRocket doesn’t have the feature.

Live sessions are the sessions of users who are currently active on your site, and you can choose to view these sessions in real-time. It’s a very handy tool for teams in charge of providing support and assistance to their site users.  

FullStory lets you view the sessions of active users on your site, in addition to the following user states once you hit “go live” (shown in the image below):

  • User is active: The user is actively engaging with your site.
  • User is inactive: The user has left the cursor in one spot for a long time.
  • Tab is unfocused: The user has minimized the tab or moved to a different one. 

The major downside to FullStory’s live sessions is the large latency in registering live users (measured average of 3 minutes) and viewing their interactions in real-time (measured average of 8 seconds), leading to lengthy and frustrating troubleshooting sessions.

On the other hand, SessionStack’s live sessions are super low latency — it shows live users almost immediately after hitting the refresh button on the “live users” page and the live session latency is consistently less than 1 second.

This low-latency environment allowed SessionStack to add a very unique and handy tool for customer support teams — co-browsing.

SessionStack is the only tool that builds on top of its live session feature with co-browsing.

Looking for a way to offer real-time guidance to site users during live sessions? Co-browsing is the solution. With this feature, you can join and engage in user sessions without the need for any additional software, plugins, or add-ons.


Co-browsing is not the same as screen sharing. One key difference is that co-browsing guarantees user file protection because you only get access to the single browser tab where they’re active on your site. And it also doesn’t require both parties to install any third-party application for it to work. You can read this article on screen sharing versus co-browsing to better understand the key differences between the two.

SessionStack’s co-browsing mode is super fast and smooth on both ends and is equipped with three key tools to enhance the overall experience:

  • A pointer: Highlights various elements on a user’s screen, without interacting with the page itself.
  • A pen: Annotates a user’s screen with pen strokes.
  • Control takeover: Gain complete control of a user’s screen (with their permission) while they’re on your site, and perform actions on their behalf.

Co-browsing works great for customer support teams during onboarding or problem-solving, as it allows them to assist customers over a phone call, chat session, or email conversation, offering prompt and personalized service in real time. While SessionStack doesn’t have a built-in chat feature, it has direct integrations with established chat tools like Intercom and Zendesk.

Winner: SessionStack. It is the go-to tool for users such as product managers, developers, and customer support teams, who need an easy-to-use, comprehensive, and robust session replay feature. SessionStack has all the key features in LogRocket and FullStory, in addition to having the best live and co-browsing features.

LogRocket vs FullStory vs SessionStack: Error Tracking

SessionStack’s dev tools track console & network logs and errors, FullStory has the most filter options, while LogRocket equips devs with the most holistic console of the three.

LogRocket FullStory SessionStack
⭐⭐⭐⭐⭐ ⭐⭐⭐ ⭐⭐⭐⭐

Error tracking is the process of identifying and resolving errors that occur on a website or web application. Errors can range from user interface glitches to critical issues that prevent site users from achieving their intended goals. 

This feature works alongside session replays so that, not only do you see the error message, but also the exact sequence of user actions and events that led to that error, and the site or application’s response to it. 

With FullStory‘s dev mode for session replays, developers can easily view log and error events that occurred during a user’s interaction, and the filters and search bar enable quick access to relevant data at any moment for efficient debugging.

Unlike FullStory, SessionStack has a dedicated logs and error tracking page which shows you when each listed event first and last occurred, the number of occurrences, and the affected users. Each of the events is also linked to a specific time stamp in a session replay, which makes it super fast and easy to dive in-depth into the source of an error.

So when you open the session replay, it plays and stops right at the point where the error occurred (marked as “1” in the screenshot above). From here, you can pull up the dev tool (marked as “2”) to show more details about the console or network error (marked as “3”).  

Similar to SessionStack, LogRocket has an “Issues” page for tracking JavaScript and network errors. You can manually or automatically group errors on this page as high impact, low impact, or ignored — a helpful feature for prioritizing your team’s efforts in resolving issues that drive the most impact.

Additionally, LogRocket balances its developer-friendly dev mode with additional features that let you view DOM elements and the performance of specific sessions.

Winner: LogRocket. It combines key features in SessionStack and FullStory with more advanced options, making error tracking and management a breeze, especially for developers and engineering teams.

LogRocket vs FullStory vs SessionStack: Heatmaps

LogRocket and FullStory gather page-specific insights, while SessionStack gives you a bird’s eye view of site-wide insights.

LogRocket FullStory SessionStack
⭐⭐⭐⭐⭐ ⭐⭐⭐⭐ ⭐⭐⭐⭐

Heatmaps are visual summaries of the interactions captured in session replays. They show you areas with the most activity (clicks, scrolls, and mouse movements) so you can identify the strengths and weaknesses of the user experience.

Mouse maps (aka hover maps) show the areas where users frequently move their cursors, scroll maps show how far down users go on a page, and click maps tell you the elements users click on the most. These clicks can be filtered by dead clicks and rage clicks. 

Dead clicks are all the “non-clickable” elements users clicked on while rage clicks occur when users click on an element multiple times in quick succession, usually signaling frustration. Read more on this in our article about click trends.

FullStory’s heatmaps track page-specific clicks and scrolls.

With FullStory, you can view the click maps and scroll maps on single pages based on all user data or specific user segments.

You can also break down click maps using the rage click and dead click filters. This feature is great for identifying how users interact with a single page but isn’t great for finding the most pressing issues across your site.

LogRocket has page-specific click, hover, and scroll maps.

Similar to FullStory, LogRocket has click maps and scroll maps but it also has hover maps which give you another layer of data on how users interact with a page. Sure, clicks are the most important engagement data points, but understanding where users hover can help you identify whole new optimization opportunities.

However, unlike FullStory’s heatmaps, LogRocket’s are embedded within session replays, so loading and switching between them is very slow and time-consuming. Also, its heatmaps can’t be filtered by user segments, which makes it difficult to get a better understanding of specific user behaviors and patterns.

SessionStack’s unique approach to heatmaps gives you a better grasp of site-wide health and performance.

Unlike FullStory and LogRocket, SessionStack doesn’t have visual heatmaps and therefore isn’t limited to only capturing data on static elements. Instead, you get a sitewide overview of the top HTML elements across your entire site or app that need attention, grouped in the following categories:

  • Most clicked elements,
  • Dead clicks, and
  • Rage clicks.

Since SessionStack tracks user interactions with individual HTML elements, it also logs interactions with dynamic elements that aren’t visible on visual heatmaps (drop-down menus, pop-ups, and accordions). Another advantage of this approach is that you don’t have to spend a bunch of time going through individual pages, looking at erratic color patterns.

Verdict: LogRocket is best for visualizing user actions with click, scroll, and hover maps. FullStory is perfect for gathering better insights based on specific user segments. SessionStack stands out by giving you the best overview of site-wide hotspots and friction points.

LogRocket vs FullStory vs SessionStack: Customer Journey Analysis

SessionStack lets you create and track funnels, FullStory gives you the best customization, while LogRocket gives deeper insights.

LogRocket FullStory SessionStack
⭐⭐⭐⭐⭐ ⭐⭐⭐⭐ ⭐⭐⭐⭐

You can analyze customer journeys on your site using the funnels feature in all three tools. Funnels can be set up to track user progress through specific steps (e.g. clicking a target element), allowing you to identify pain points and make informed decisions about site improvements. An example of a funnel is shown below:

SessionStack’s funnel creation and conversion tracking is simple and straightforward.

SessionStack lets you add unlimited steps to your funnel with the following four event types: viewed a page, clicked an element, rage click, and dead click.

Additionally, you can easily track conversions at each stage of your funnel with graphs, and view the session recordings of users who either converted or dropped off at each step of your funnel. This is very useful for identifying areas of friction within your design and taking prompt action to remove them. 

FullStory has the most options for funnel creation and conversion tracking.

FullStory’s funnel features are very similar to SessionStack, however, FullStory has much more options for creating highly customized funnels. 

In addition, you can view funnel conversions based on different user groups (e.g. country, device, browser, etc.) and also view side-by-side comparisons of up to 4 user segments. These are very helpful for uncovering common user patterns and differences, allowing for targeted improvements to be made to any given funnel.

LogRocket has multiple views for viewing conversion graphs. 

LogRocket has multiple views for conversion graphs, the most notable one being “path analysis”. This gives you a visual summary of all the different paths users take when they deviate from the sequence of steps outlined in your funnel. It creates these alternate routes organically (as shown in the image below), without the need for any manual setup.

The path analysis view helps you identify the distracting elements that turned users away but also understand where they went and what prevented them from reaching the end of your funnels.

So it’s a great tool for testing your marketing funnel thesis’ because you get to see the other side of it.

For example, if you’re trying to understand where readers go from your blog posts with FullStory, you either have to set up tracking on each link on your page, or you have to use session replays to find out where users are going. You can imagine how annoying that would be if you want to analyze 100 blog posts… but that’s not a problem with LogRocket.

Verdict: SessionStack is best for creating simple yet effective funnels and conversion graphs for quick decision-making, FullStory is best for gaining deeper insights into specific user groups for making targeted improvements. And LogRocket’s path analysis view is very helpful for fixing potential distractions preventing users from moving through a funnel.
