SSE Inspector
Chrome DevTools extension specifically designed for Server-Sent Events (SSE), making SSE debugging more efficient and convenient.
What Problem Does It Solve?
Difficult to find SSE requests — Manually searching through numerous requests in the Network panel is time-consuming.
Message content scattered — SSE messages are spread across multiple EventStream records, making it hard to get a complete picture.
JSON formatting trouble — Need to manually copy content and paste it into another tool to format JSON.
Multiple connections mixed — Multiple SSE connections are mixed together, making them hard to distinguish.
Cannot search history — No support for searching through historical messages.
History lost on refresh — Historical records are lost after refreshing the page.

Privacy Policy
Last Updated: January 14, 2026
Introduction
Welcome to SSE Inspector. This Privacy Policy explains how we handle your information when you use our browser extension. We are committed to protecting your privacy and ensuring transparency about our data practices.
Information We Collect
SSE Inspector is designed with privacy as a core principle. The extension:
- Does not collect personal information — We do not gather any identifiable information about you
- Does not track your browsing history — Your web activity remains completely private
- Does not use analytics or tracking tools — No third-party services monitor your usage
- Processes data locally only — All SSE stream monitoring happens within your browser
How We Use Information
The extension accesses the following data solely for its core functionality:
Network Request Monitoring
SSE Inspector monitors network requests to identify and display Server-Sent Events (SSE) streams. This monitoring occurs entirely within your browser's developer tools and is temporary — data is only held in memory while the DevTools panel is open.
Local Storage
The extension may use browser local storage to save your preferences and settings. This data never leaves your device and is stored securely within your browser's sandboxed environment.
Data Sharing and Third Parties
We want to be crystal clear:
- We do not sell your data
- We do not share your data with third parties
- We do not have servers that receive your data
- No external analytics or advertising services are integrated
Since all processing happens locally in your browser, there is no data transmission to any external entity.
Permissions Explained
SSE Inspector requires certain browser permissions to function. Here's why:
Data Security
All data processed by SSE Inspector remains within the secure, sandboxed environment of your browser. We follow browser extension security best practices to ensure:
- No unauthorized access to your data
- Isolation from other extensions and web pages
- Compliance with browser security policies
Your Rights and Control
You have complete control over the extension:
- Disable or Remove: You can disable or uninstall the extension at any time through your browser settings
- Clear Data: You can clear any locally stored preferences by removing the extension
- Transparency: The extension's source code behavior is transparent through the browser's extension inspection tools
Children's Privacy
SSE Inspector is a developer tool and is not directed at children under 13 years of age. We do not knowingly collect information from children. Since we don't collect any personal information at all, this risk is inherently minimized.
Changes to This Privacy Policy
We may update this Privacy Policy from time to time to reflect changes in the extension or legal requirements. When we do, we will update the "Last Updated" date at the top of this page. We encourage you to review this policy periodically.
Continued use of the extension after changes constitutes acceptance of the updated policy.
Open Source and Transparency
We believe in transparency. The extension's code can be inspected through your browser's extension management interface, allowing technically inclined users to verify our privacy claims.
