  "account": "Sentinel-IR Playground has launched in beta, offering developers a browser-based interface to analyze their code for structural information. It allows users to paste code or upload files, with no need to install anything, open terminals, or send their source code elsewhere. The tool runs locally in the browser using WebAssembly, preserving the privacy of the developer's code. It supports JavaScript, TypeScript, TSX, and Python, providing risk levels, security signals, imports, routes, operations, and compact information that AI agents can utilize. The playground's design prioritizes privacy, with no server-side application code, analytics, or source-code upload mechanisms. Results are tested alongside the Node.js package to ensure consistency, and the application is built with a Content Security Policy to restrict connections to only the application's own origin. However, the beta release is not a complete security auditing platform and has certain limitations, such as not guaranteeing that a low risk level or an empty list of signals means the program is safe.",
