CSP Builder: a small tool that solves a specific problem

CSP Builder is a visual tool that simplifies creating Content Security Policies, reducing the risk of XSS and code injection. It provides a form-based interface to compose directives, catching syntax errors and common missteps. The output is a syntactically valid policy header ready for deployment. This tool lives in the browser, ensuring privacy and no signup is required. It's a valuable addition to DevTools, a collection of 200+ free browser utilities.
