Stream Bridge Stream Bridge

NDI browser viewer without NDI Tools

Stream Bridge lets anyone view an NDI source without installing NDI Tools or joining the production network - just a link that opens in a browser, with production audio and controlled access built in.

Signal Flow

4 Simple Steps

  1. Pick an NDI source

    Programme, cameras, multiview, graphics or NDI HX from your NDI network.

  2. Pair the app

    Install Stream Bridge, add a device on the dashboard and enter its connection key.

  3. Share a link

    Send a viewer link, password optional. No port forwarding or network admin needed.

  4. They watch live

    Open it in Chrome, Firefox, Edge or Safari. Direct where possible, via our cloud when not.

How it works

NDI discovery and capture stay on the paired production device - the person watching doesn't need any of that. Pick the source, create a stream, and share a link that opens straight into a browser player.

The same stream can have multiple viewer links for different roles. Each one can carry its own URL, password, branding, controls and audio without touching the underlying NDI source.

The viewer doesn't need access to the NDI LAN, a VPN or a forwarded port. We negotiate a direct connection and use our cloud network automatically when the endpoints can't connect directly.

You stay in control after the link goes out - viewer counts, connection information, device performance and live bitrate changes are all in the dashboard, while the person watching just sees the player.

Technical Breakdown

A closer look at NDI discovery, browser playback, production audio, latency, connection routes and link-level control.

Supported Sources

NDI programme, multiview, camera and graphics sources on the paired device.

Explore details

Stream Bridge works with full-bandwidth NDI and NDI HX sources the paired device can see - cameras, vMix, OBS, PTZ cameras, graphics systems and other NDI sources.

Discovery is controlled per device, so you can turn off input families you don't use, or restrict results to local sources on a busy network.

Audio

Up to 16 channels, plus optional return communication.

Explore details

Stream Bridge can capture up to 16 audio channels from a single NDI source, delivered as individually controllable programme tracks.

Different audiences don't need the same audio. Configure extra tracks and communication tools at the viewer-link level to suit each role.

Performance

Real-time H.264 encoding through NVENC or CPU.

Explore details

Encoding can run on NVIDIA NVENC or the CPU. NVENC generally gives the lowest latency and CPU use; CPU mode is useful on systems without compatible hardware or where GPU capacity is already committed.

Live telemetry makes encoder headroom visible. If load's getting close to the top or frames start dropping, cut back on concurrent work or move the encode to better hardware.

Viewer Quality & Latency

Low-latency playback in Chrome, Firefox, Edge and Safari.

Explore details

This page is about the viewer side; the NDI-to-browser page has the full technical breakdown. Every viewer is a separate connection, and your bitrate applies to each - two viewers at 5Mbps needs roughly 10Mbps upload.

A static presentation and a fast sports camera put very different demands on the encoder, so tune bitrate live while watching device and viewer behaviour.

Networking

Direct connection first, cloud relay as a fallback.

Explore details

There's no manual IP exchange or router forwarding required. Each session negotiates its own route automatically.

Corporate and venue networks sometimes block a direct connection. When that happens, Stream Bridge falls back to relay, and you can drop the bitrate if the longer route has less headroom.

Security & Customisation

Custom links, passwords, branding and controls per viewer.

Explore details

Custom URLs, passwords, colours, logos and controls let you match the viewer experience to its audience. Up to 25 viewer links can be created per stream.

Security isn't just about the connection - keep your dashboard account protected, keep pairing keys private, password anything sensitive, and don't reuse access beyond the event it was made for.

NDI browser viewer

Frequently Asked Questions

Practical answers about NDI Tools, browser support, latency, audio, bandwidth and viewer access.

How it works

No. Only the paired device needs access to the NDI source - remote viewers just open the assigned link in a supported browser.

Chrome, Firefox, Edge and Safari. Chrome's the most reliable for WebRTC, especially where advanced audio features are in use.

Latency's usually in the hundreds of milliseconds rather than seconds. The final figure depends on encoding, browser buffering, network conditions and whether relay's required.

Comparisons & reliability

Yes. Viewer links can include source channels and additional audio feeds, with independent browser controls.

Each viewer is a separate connection - as a planning example, two viewers on a 5Mbps stream need roughly 10Mbps of sender upload before overhead.

Yes. Separate links can carry different URLs, passwords, branding, controls and communication options while using the same underlying NDI stream.
