A fast, precise tool for developers and streaming engineers to test direct video URLs, check CORS configurations, and validate HTTP range request support instantly.
Paste your link below to start streaming immediately in your browser.
Built for speed and privacy — no bloat, no sign-ups, no nonsense.
Validate if your media server has correct Cross-Origin Resource Sharing (CORS) headers configured for browser streaming.
Test your CDN or bucket for 'Accept-Ranges: bytes' to ensure the video supports seekable progressive streaming.
Automatically inspects the Response Content-Type to verify if the file is an MP4, WEBM, or M3U8.
Provides instant feedback on Time to First Byte (TTFB) and buffering performance from the browser's view.
Paste long AWS S3 or Google Cloud presigned URLs to confirm if token signatures restrict browser playback.
Catch HTTP 403 Forbidden or 404 Not Found errors before you deploy your video links to users.
Three steps from link to stream. No friction, no fuss.
Copy the final direct URL of your video endpoint (e.g., from an S3 bucket or a cloud storage provider).
Paste it into the tester. Our browser client will attempt an immediate fetch and partial content load.
If playback succeeds with smooth seeking, your storage configurations and HTTP headers are production-ready.
