Overview

Product summary

Review the store description, core capabilities, and common use cases.

This is an Open Source SAML debugger for Chrome. It operates as another panel in the Chrome Developer Tools section, which monitors the traffic in the current active tab. This panel is trying to replicate what the Firefox version of SAML Tracer does as there wasn't a good enough one (or any) for Chrome at the time of writing this.

GitHub Repo: https://github.com/milton-lai/saml-chrome-panel

Feel free to branch and help make this even better!

It is designed to display all network traffic, along with the request and response data. If there is a SAML request or response, then it will grab the message, format it nicely and show it to you in another tab.

AI product read

SAML protocol debugger that adds a dedicated panel to Chrome Developer Tools for monitoring, decoding, and displaying SAML authentication requests and responses

Developers and identity engineers debugging SAML-based Single Sign-On (SSO) flows in Chrome lacked a good tool equivalent to Firefox's SAML Tracer. This extension fills that gap by capturing and nicely formatting SAML messages within Chrome DevTools.

User opens Chrome DevTools and navigates to the SAML panel. As they browse or trigger SAML authentication flows, the extension intercepts network requests, detects SAMLRequest/SAMLResponse parameters, decodes the base64/deflated XML payloads, and displays them in a formatted view. Users can toggle between original and formatted SAML views, filter SAML-only traffic, search within messages, and export/import the captured data.

Target users: Web developers implementing SSO/SAML authentication / Identity and access management engineers / IT administrators troubleshooting SAML-based authentication / Security engineers analyzing SAML assertions

Monetization

No paid features detected

This is an open-source extension with no payment logic, subscription code, feature gating, or upgrade UI. The 'pro' keyword matches were all JavaScript prototype/apply calls in vendor libraries (angular.min.js, panel.js). The 'license' matches were BSD/MIT license headers in copyright comments. The store description explicitly states it is open source with a GitHub repo link.

Confidence: 98
Payment platform: --
Source: AI / High
Login required: No
Reason: No login logic exists in the extension. The 'log in' heuristic match was a false positive from CSS styling for CodeMirror dialog components (panel/vendor/assets/stylesheets/codemirror-dialog.min.css). The 'auth' match was just a copyright header in devtools.js line 1. The extension operates entirely locally within Chrome DevTools with no account creation, authentication, or external service login required.
