SAML Response Diff is a lightweight, client-side web application designed to help developers and identity engineers compare and analyze SAML Assertions (responses sent to SP). It provides a side-by-side comparison of key fields and an interactive XML explorer.

- Field-by-Field Comparison: Automatically extracts and compares critical SAML elements like Issuer, Subject (NameID), Audience, and Attributes.
- Namespace Agnostic: Works seamlessly with different SAML prefixes (saml:, saml2:, or none) and various Identity Provider formats (Okta, Azure AD, Ping, etc.).
- Interactive XML View: A syntax-highlighted XML explorer with collapsible branches to easily navigate deep structures.
- Customizable Labels: Rename your assertions (e.g., "Production" vs "Staging") for clearer reports.
- Privacy First: 100% client-side processing. Your sensitive SAML data never leaves your browser and is never sent to a server.
- Portable: A single HTML file with no build step required.
