Smartlook is a qualitative analytics solution for web and mobile helping over 250,000 businesses of all sizes and industries answer the โ€œwhysโ€ behind usersโ€™ actions โ€” why do users churn, or why arenโ€™t they using a feature, or why are they skipping onboarding? Now you can eliminate the guesswork.

With a unique feature set, Smartlook gives you a way to finally understand user behavior at the micro level. Always-on visitor recordings show you what every last visitor does on your website or app, and heatmaps give you mass data about where most people click and scroll. Automatic event tracking lets you know how (and how often) your visitors do specific things, while conversion funnels take those events and show you how much success you're having with conversions.

Started in 2016, Smartlook has grown into a complete solution for qualitative analytics, making guesswork a thing of the past. Stop wondering why, and start getting answers today.

Witnes is a performance monitoring tool that gives you a per-session breakdown of how your website actually loaded for each visitor. Unlike aggregate metrics that hide outliers, Witnes records every page load individually โ€” showing you the frontend rendering time, backend response, network conditions, and payload size in one view. It's built for modern web apps where traditional analytics fall short: SPAs, hybrid frameworks, and pages with deferred content that make standard Web Vitals misleading. When a customer reports that your site was slow, Witnes gives you an X-ray link to see exactly what they experienced โ€” no guessing, no reproducing in-house.

Smartlook features and specs

    The tool supports web, iOS, and Android platforms, enabling businesses to track user behavior across different devices seamlessly.
  • Advanced Filtering
    Users can apply advanced filters to their data, which helps in segmenting users and understanding specific behaviors more accurately.
  • Integrations
    Smartlook integrates with various third-party tools like Google Analytics, Slack, and others, providing a more versatile analytical environment.
  • Session Recordings
    Smartlook provides detailed session recordings for mobile apps, allowing teams to watch real user interactions, see exactly how users navigate through the app, and identify usability issues or friction points in the user experience.
  • Heatmaps for Mobile
    The platform offers touch heatmaps specifically designed for mobile apps, helping teams visualize where users tap, scroll, and interact most frequently, enabling data-driven UI/UX design decisions.
  • Event-Based Analytics
    Smartlook allows you to track custom events and user actions without requiring extensive coding, making it easier to monitor funnels, conversions, and key user behaviors within the mobile app.
  • Crash and Anomaly Detection
    The tool helps identify crashes and anomalies by linking session recordings to error events, enabling developers to see exactly what the user was doing before a crash occurred, which significantly speeds up debugging and issue resolution.

Possible disadvantages of Smartlook

  • Data Privacy Concerns
    Recording user sessions could potentially raise privacy issues if not managed correctly, requiring strict adherence to data protection regulations.
  • Learning Curve
    Even with a user-friendly interface, new users might still encounter a learning curve when trying to utilize all features effectively.
  • Cost
    While offering a free tier, the costs can add up for premium features or advanced usage, which might be a constraint for smaller businesses.
  • Performance Impact
    The presence of session recording scripts can sometimes slow down website performance, affecting the user experience negatively.
  • Limited Free Plan
    The free plan comes with limitations in terms of data retention and the number of sessions that can be recorded, which might not be sufficient for larger businesses or detailed analysis.
  • Privacy and Compliance Concerns
    Capturing session recordings on mobile apps raises significant privacy concerns. Teams must carefully configure data masking and ensure compliance with GDPR, CCPA, and app store privacy policies, which adds complexity to implementation.
  • Data Sampling at Scale
    For apps with high traffic volumes, Smartlook may sample data rather than capturing every session, which means some user interactions could be missed and analytics may not represent the full picture of user behavior.
  • Learning Curve for Advanced Features
    While basic session playback is straightforward, setting up advanced features like custom event tracking, funnel analysis, and proper data filtering requires technical knowledge and time investment, which can slow down initial adoption.

Questions & Answers

As answered by people managing Smartlook and Witnes.io.

What makes your product unique?

Witnes.io's answer:

Per-session visibility โ€” instead of aggregate metrics that hide outliers, every individual page load is recorded so you can look up exactly what a specific user experienced, including a full network waterfall breakdown.

While it's also built for modern web applications.

Why should a person choose your product over its competitors?

Witnes.io's answer:

Most performance tools show you averages and percentiles โ€” useful, but they can't tell you why this customer had a bad experience. Witnes records every session individually so you can pull up any page load and see exactly what happened, without needing to reproduce it or wait for it to happen again.

How would you describe the primary audience of your product?

Witnes.io's answer:

Development teams and customer support staff at companies with modern web apps who need to diagnose specific user-reported performance issues.

What's the story behind your product?

Witnes.io's answer:

Built after spending a week trying to diagnose why customers kept reporting slow page loads, while all the metrics said everything was fine. The problem turned out to be that standard analytics weren't built for modern web apps โ€” they measure server delivery but miss what happens after the JavaScript bundle lands. Witnes was built to close that gap.

Which are the primary technologies used for building your product?

Witnes.io's answer:

The core is its javascript tracker, which is added on every page load. The backend is supported by c# dotnet 10 and postgresql at its core. The frontend is built using Astro and React
