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.

    The platform is easy to navigate, making it accessible for users who may not be experienced with analytics tools.

  • Cross-Platform Support
    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 CodeKitHub and Smartlook.

What makes your product unique?

CodeKitHub's answer

  • No sign-up, no upload โ€” every tool runs entirely in your browser via JavaScript. Nothing you paste, type or upload ever touches a server, which matters for anything sensitive (passwords, personal photos, private notes).
  • No daily usage caps โ€” most competing free tool sites throttle you after a few uses per day or push you toward a paid tier. CodeKitHub doesn't.
  • 13 languages โ€” most free tool aggregators are English-only; CodeKitHub covers English, Spanish, French, German, Japanese, Korean, Chinese and more.
  • 120+ tools in one place โ€” JSON formatting, encoding/decoding, image and PDF conversion, QR codes, unit/date calculators, and more, without bouncing between a dozen single-purpose sites.

Why should a person choose your product over its competitors?

CodeKitHub's answer

Compared to single-purpose sites like JSONFormatter.org or CodeBeautify that only handle one task, CodeKitHub covers the same ground plus image, PDF, QR, and calculator tools in one place โ€” useful if you regularly switch between different tool types during a workday.

Unlike FreeFormatter (which recently shut down its service), CodeKitHub's tools require no backend at all โ€” everything runs as static, client-side JavaScript, so there's no server cost pressure driving ads, paywalls, or future shutdowns of the kind that killed similar sites.

If you need a tool site in a language other than English โ€” Spanish, French, German, Japanese, Korean, Chinese, and others โ€” CodeKitHub is one of the few free tool sites that actually localizes the full interface rather than just running it through machine translation on top of an English-only tool.

How would you describe the primary audience of your product?

CodeKitHub's answer

CodeKitHub serves two overlapping groups:

  • Developers who need a quick JSON formatter, Base64/URL encoder, hash generator, or regex tester without installing a CLI tool or opening a full IDE โ€” the kind of task that comes up mid-workflow and just needs a fast, no-friction answer.
  • Everyday users handling one-off tasks like compressing a photo before uploading it somewhere, generating a QR code, converting units, or running a quick date/percentage calculation โ€” people who don't want to install an app or sign up for an account just to do something once.

Traffic data shows both groups in practice: technical tools (QR generator/decoder, Base64 encoder, JSON tools) draw developer-heavy referral sources like Hacker News and ChatGPT, alongside broader organic search traffic for everyday utility tasks.

What's the story behind your product?

CodeKitHub's answer

CodeKitHub started as a small set of browser-based developer utilities and grew into a 120+ tool collection covering JSON formatting, encoding, image/PDF processing, calculators and more. The core principle from the start was that every tool should run entirely client-side โ€” no backend, no data leaving the user's browser โ€” which keeps the tools fast, private, and cheap enough to run without ads getting in the way. The site has since expanded to 13 languages to serve users beyond English-speaking markets.

Which are the primary technologies used for building your product?

CodeKitHub's answer

  • Astro โ€” static-site framework, used to generate all tool pages and handle the multi-language routing (13 locales)
  • Vanilla JavaScript/TypeScript โ€” every tool's actual logic runs client-side, no backend or API calls involved
  • Cloudflare Pages โ€” static hosting and deployment
  • Google Analytics 4 โ€” the only external service the site talks to, for traffic analytics
