What is Deepscan?

DeepScan is a static code analysis tool designed to improve JavaScript and TypeScript code quality. It goes beyond traditional linting tools like ESLint by employing data-flow analysis to understand the execution flow of your program, accurately identifying potential errors and code issues without requiring the code to be run. This allows developers to catch mistakes early in the development cycle, before they are committed. The platform integrates seamlessly with GitHub, continuously analyzing team projects as commits are pushed. It provides an overall quality status for teams, tracks issues over time even with code changes, and assigns a simple 'Poor', 'Normal', or 'Good' grade to projects to motivate maintaining clean code. DeepScan supports modern web technologies including ECMAScript specifications, React, Vue.js, and Astro, making it suitable for individual developers and teams working on contemporary web applications. DeepScan is ideal for development teams and individual developers who want to maintain high code quality, reduce bugs, and ensure best practices are followed in their JavaScript and TypeScript projects. Its continuous analysis and grading system provide ongoing insights into project health, increasing confidence before code deployment.
