Free engineer tools
11 live tools. Zero signup.
Every tool runs in your browser and measures the real thing. No marketing number in place of a measurement. Start with the job you are trying to do.
Test your connection
Is this link broadcast-ready? Sustained throughput, loss and jitter, measured the way a live encoder sees it.
Streaming Connection Diagnostic
Bandwidth, latency, packet loss, jitter, measured in about 20 seconds. Free.
Streaming Speedtest
Upload, download, and stability tested against what a live stream needs.
Packet Loss Test
Measure packet loss in your browser. The #1 cause of stuttering, frozen, and dropped live streams.
Jitter Test
Measure timing variance between packets. High jitter = unstable streams.
Check the network path
Will the stream get through? Inbound reachability, NAT behaviour, TURN reachability and who is on the other end of your IP.
Inbound Port Reachability
Can the internet reach a TCP port at your location? For listeners and port forwards. Outbound streaming does not need it.
NAT Type
Detect NAT type and symmetry. Critical for WebRTC peer-to-peer setup.
TURN Test
Verify TURN server reachability for WebRTC and remote-director workflows.
IP Checker
Public IP, ASN, geolocation. Useful for whitelist setup and routing checks.
Set up your stream
Get the ingest and playback plumbing right before it hits the encoder.
URL Builder
Parse and validate SRT, RTMP, and WHEP ingest URLs before they hit your encoder.
HLS Analyzer
Pull an HLS manifest, validate variant tracks, segment durations, codec strings.
RTSP Tester
Test an RTSP stream URL end-to-end. Connects, reports codec + framerate.
Stream Key Tester
Validate stream keys against ingest endpoints before going live.
Align the programme
A wall-clock timecode in the picture to measure glass-to-glass latency and line up cues on the recording.
