Overview
SessionStack
SessionStack helps you understand exactly how users interact with your web applications by capturing every click, scroll, and mouse movement. You can watch high-fidelity session replays to identify where users get stuck or why they drop off, allowing you to make data-driven improvements to your conversion funnels. It goes beyond simple analytics by linking user actions directly to technical console logs and network errors.
You can also use the platform for real-time customer support through its integrated co-browsing feature. This allows you to join a user's session instantly to guide them through complex tasks without requiring any software installations on their end. Whether you are a product manager looking for UX insights or a developer debugging production issues, the platform provides the visual and technical context you need to improve your digital experience.
Surfly
Surfly is a high-performance collaboration platform designed to help you provide instant, visual support to your customers. Unlike traditional screen sharing, its proxy-based co-browsing technology lets you jump onto any website or web app with a customer to navigate together in real-time. You can highlight elements, fill out forms, and even sign documents digitally without asking your customers to download software or install browser extensions.
The platform is built with a security-first approach, allowing you to mask sensitive data like credit card numbers while you assist. It is ideal for financial services, insurance, and retail companies that need to bridge the gap between digital self-service and human interaction. You can easily integrate it into your existing tech stack to improve first-contact resolution and boost your conversion rates.
