A web application is a streaming service accessed through a browser, with no install required. It's the most universally reachable OTT surface — any device with a modern browser can play, making it the default entry point for many services.
Enveu take
The web app is your zero-friction front door — no store, no install, instantly shareable by link — which is exactly why it's often where discovery and first playback happen.

What it is
A web application delivers streaming through the browser using HTML5 video, Media Source Extensions for adaptive bitrate, and Encrypted Media Extensions (EME) for DRM. It requires no download or store approval, runs on desktop and mobile browsers alike, and is the most frictionless way for viewers to reach a service.
- Browser-based via HTML5/MSE/EME
- No install or store approval
- Runs across desktop and mobile browsers
Why it matters
The web app reaches the widest possible audience: anyone with a browser, on any OS, via a shareable link and no install. It's often where viewers first discover and try a service, and it's the easiest surface to update. Strong browser playback (adaptive streaming, DRM via EME) makes the web a first-class OTT platform, not just a fallback.

Frequently asked questions
What is a web application in OTT?
A web application is a streaming service accessed through a browser with no install required — the most universally reachable OTT surface across devices and OSes.
Can browsers play DRM-protected video?
Yes — modern browsers support Encrypted Media Extensions (EME) with DRM systems like Widevine, PlayReady, and FairPlay, plus adaptive streaming via Media Source Extensions.
What's the difference between a web app and a PWA?
A web app runs in the browser; a PWA adds installability, offline support, and push notifications on top of the web app, making it feel more like a native app.
Does a streaming web app need DRM?
If you license premium content, yes — rights holders generally require multi-DRM (Widevine, PlayReady, FairPlay) via Encrypted Media Extensions. For owned or non-premium content, AES-encrypted HLS with signed URLs and token auth is often sufficient.
How do I make a streaming web app SEO-friendly?
Server-render or pre-render title and category pages so crawlers see real HTML, give every title a unique URL with descriptive metadata, and add VideoObject schema. Keeping playback behind auth is fine — it's the discovery pages that need to be indexable.
