Four new applications have been introduced to the GitHub Marketplace to enhance code review, security, and monitoring processes. AccessLint integrates automated web accessibility testing into development workflows by reviewing pull requests for accessibility issues, providing timely feedback. Dependabot helps manage Ruby, JavaScript, Python, and PHP dependencies by identifying outdated requirements and opening pull requests to update them. Greenkeeper offers real-time monitoring for npm dependencies, ensuring safety and consistency by sending actionable pull requests and issues. LogRocket provides a unique monitoring solution by allowing developers to replay problems with a video recording that captures user interactions, console logs, network requests, and application states.
