Hacksplaining is a web-based security training platform designed specifically for web developers. The platform provides free, self-paced educational content covering a broad range of security vulnerabilities that developers are likely to encounter in their work. The core learning methodology involves hands-on exercises where users interact with real, vulnerable applications directly in the browser. After exploiting a vulnerability, learners are then shown how to write secure code to remediate the issue. This approach combines practical attack simulation with defensive coding guidance. The platform covers 39 distinct vulnerabilities in detail, including content aligned with the OWASP Top Ten — a widely recognized reference list of critical web application security risks. Hacksplaining also addresses compliance-related training, with specific content mapped to PCI DSS requirements. In addition to its free individual offering, Hacksplaining provides enterprise licensing for organizations that want to train development teams at scale. The platform reports over 523,000 registered users and more than 500 paying customers. The target audience is primarily software developers and development teams, as well as security-conscious engineering managers. The content is framed as practical and actionable, aimed at developers who need to understand and address security issues without extensive security backgrounds.
