VDO.Ninja offers specialized testing tools to evaluate your connection quality for video streaming, focusing on metrics critical for WebRTC performance that standard speed tests don't measure.
The Speed Test provides real-time feedback on your WebRTC connection quality:
Tests your camera or screen-sharing streaming performance
Visualizes critical metrics with live graphs:
Bitrate (kbps)
Buffer delay (ms)
Packet loss percentage
Allows testing against different global regions
Provides detailed logs of connection statistics
Supports variable bitrate testing (low/high/default)
This tool is ideal for quick diagnostics and troubleshooting your own setup before important streams.
The Check Test runs comprehensive automated tests of a user's system and connection:
Conducts network bandwidth measurements via Cloudflare
Tests camera and microphone access
Performs automated testing at increasing bitrates (2500 → 4000 → 6000 kbps)
Takes approximately 90 seconds to complete
Automatically stores results on the server for up to 7 days
Generates shareable results links
Pre-checking guests days before a live stream is crucial for identifying and resolving technical issues in advance, preventing embarrassing on-air failures and giving production teams adequate time to implement solutions without the pressure of an imminent broadcast.
Shareable Results: After completion, provides a link to results that can be shared with stream organizers
Pre-assigned IDs: Use ?id=xxx parameter to pre-assign test IDs (example: https://vdo.ninja/check?id=exampleGuest123)
Screening Tool: Ideal as a pre-tech-check for guests before important streams
View comprehensive test results including:
Average video bitrate
Buffer delay (video latency)
Packet loss statistics
CPU/network limitation indicators
Browser and device information
Codec support details
Packet loss is critical for WebRTC video quality but is not measured by standard speed tests. Even small amounts of packet loss can cause:
Video freezing
Audio dropouts
Quality degradation
Increased latency
The VDO.Ninja tests specifically measure packet loss percentages, with ideal results being under 0.1% and problematic levels exceeding 1%.
These tools are essential for properly evaluating streaming readiness, especially when screening multiple participants before important broadcasts.
