Direct Video Link Tester & Validator
A fast, precise tool for developers and streaming engineers to test direct video URLs, check CORS configurations, and validate HTTP range request support instantly.
CORS Checking
Validate if your media server has correct Cross-Origin Resource Sharing (CORS) headers configured for browser streaming.
HTTP Range Requests
Test your CDN or bucket for 'Accept-Ranges: bytes' to ensure the video supports seekable progressive streaming.
Format Auto-Detection
Automatically inspects the Response Content-Type to verify if the file is an MP4, WEBM, or M3U8.
Latency Testing
Provides instant feedback on Time to First Byte (TTFB) and buffering performance from the browser's view.
Presigned URL Verification
Paste long AWS S3 or Google Cloud presigned URLs to confirm if token signatures restrict browser playback.
Error Diagnostics
Catch HTTP 403 Forbidden or 404 Not Found errors before you deploy your video links to users.
How It Works
Input the Raw Endpoint
Copy the final direct URL of your video endpoint (e.g., from an S3 bucket or a cloud storage provider).
Run the Validator
Paste it into the tester. Our browser client will attempt an immediate fetch and partial content load.
Evaluate Results
If playback succeeds with smooth seeking, your storage configurations and HTTP headers are production-ready.
