If you just want to know whether Morrowind in a browser is a real play path or a novelty tab, this is the decision guide. OpenMW-Web can run a free demo world or your own legal install inside desktop Chrome. It is not a Bethesda cloud stream, and it is not a replacement for a native OpenMW install if you care about long campaigns and heavy mods.
What OpenMW-Web actually is
OpenMW-Web is Virtastic's WebAssembly build of OpenMW, the open-source Morrowind engine. The hosted play page is morrowind.virtastic.app. The engine runs client-side. It reads data from your machine. There is no game data bundled for the full campaign.
There are no plugins and no streaming service. The engine runs locally and reads game data from your machine.
That line is from the project's README. The same docs also state the project is not affiliated with or endorsed by Bethesda or ZeniMax. There is no official Bethesda browser client here.
How to try it in five minutes
Open desktop Chrome or Chromium (the README marks Firefox, Safari, and mobile as unsupported).
Go to morrowind.virtastic.app.
Start the example world if you only want a free demo island with NPCs and creatures. No Morrowind purchase required.
Or choose Bring your own Morrowind and point the picker at a legal Data Files folder that contains Morrowind.esm and Morrowind.bsa. Tribunal, Bloodmoon, and nearby .esp / .esm / .bsa mods in that folder are detected automatically.
