Datasette Apps launch: Host custom HTML apps securely within Datasette

By PulseAugur Editorial · [1 sources] ·

Simon Willison has launched Datasette Apps, a new plugin for Datasette that allows users to host custom HTML and JavaScript applications within a sandboxed iframe. These applications can execute read-only SQL queries against data in Datasette, and with proper configuration, can also run write queries. The system utilizes a combination of iframe sandboxing and Content Security Policy (CSP) headers to ensure security, preventing unauthorized access to cookies, localStorage, and external HTTP requests. This feature is inspired by concepts like Claude Artifacts and aims to provide a powerful way to integrate custom frontends with relational database backends. AI

IMPACT Enhances the integration of custom frontends with relational databases, potentially influencing how AI agents interact with data.
