Overview
Glassbox
Glassbox gives you a complete view of how customers interact with your digital products by capturing every click, scroll, and hover in real-time. You can watch high-fidelity session replays to see exactly where users struggle, allowing you to fix bugs and friction points before they impact your bottom line. It automatically surfaces technical errors and performance issues, so your engineering and product teams can stop guessing and start solving.
The platform goes beyond simple replays by providing AI-driven insights into user behavior and journey mapping. You can quantify the financial impact of specific site issues and prioritize your roadmap based on actual user data. Whether you are managing a complex e-commerce site or a high-traffic mobile app, it helps you create smoother digital experiences that keep your customers coming back.
PostHog
PostHog gives you a complete suite of product tools in a single platform, so you don't have to stitch together multiple different services. You can track how users move through your application, identify where they get stuck using session recordings, and test new ideas with built-in A/B testing. It helps you understand the entire user journey from the first click to long-term retention.
Because it is open-source and offers a self-hosting option, you maintain full control over your data privacy and compliance. Whether you are a solo founder or part of a large engineering team, you can deploy features faster and make data-driven decisions without waiting for a data analyst to run manual queries for you.
