About the project

What is Cross Check?

A SaaS Chrome extension designed to simplify QA, bug reporting, and testing workflows for development teams. Traditional bug reporting is often slow, unclear, and filled with back-and-forth communication. The extension solves this by enabling instant session replays, annotated screenshots, and effortless bug sharing, helping QA testers, developers, and project managers collaborate. The goal is to eliminate friction in bug reporting while maintaining scalability, speed, and ease of use.

Objectives

Build a SaaS-based bug reporting tool with strong focus on QA workflows. Provide team collaboration through sharing and integration with tools like Jira/ClickUp. Enable instant replay and screenshot capture for precise bug documentation. Ensure high performance, scalability, and security for a growing user base.
