Internet Explorer 11, Chrome [1], Firefox [1] (not in a private window), Edge [1], Safari [1] and any mobile versions of these. It will probably also work on any derivatives of these.
1: Because of #230, only more recent versions are supported.
TorBrowser ships a crippled IndexedDB implementation and will not work. At some point we should support a memory store as a fallback, but that will still give a sub-par experience with end-to-end encryption.
It used work in pre-webkit Edge, to have it work on Windows Phone, but that support has probably bit-rotted as it isn't tested anymore.
The following browser extensions are known to break Hydrogen
- uBlock Origin (Some custom filters seem to block the service worker script)
- Try locating the filter that is blocking the service worker script in the uBlock Origin logger, and disabling that filter. Otherwise, the easiest solution is to disable uBlock Origin for the Hydrogen site (by opening the uBlock Origin popup and clicking the large power button symbol). It is possible to re-enable it after logging in, but it may possibly break again when there is an update.
You can install Hydrogen as a PWA using Chrome/Chromium on any platform or Edge on Windows. Gnome Web/Ephiphany also allows to "Install site as web application". There is no Electron build of Hydrogen, and there will likely be none in the near future, as Electron complicates the release process considerably. Once Hydrogen is more mature and feature complete, we might reconsider and use Tauri if there are compelling use cases not possible with PWAs. For now though, we want to keep development and releasing fast and nimble ;)
If you can't find an easy way to locate the feature you are looking for, then the anwser is usually "no, not yet" :) But here are some things people have asked about in the past:
That's not yet a feature, as hydrogen just uses a single line text box for message input for now.
You can only verify by comparing keys manually currently. In Element, go to your own profile in the right panel, click on the Hydrogen device and select Manually Verify by Text. The session key displayed should be the same as in the Hydrogen settings. You can't yet mark your Element session as trusted from Hydrogen.
Published builds can be found at https://github.com/vector-im/hydrogen-web/releases. For building your own, you need to checkout the version you want to build, or master if you want to run bleeding edge, and run yarn install and then yarn build in a console (and install nodejs >= 15 and yarn if you haven't yet). Now you should find all the files needed to host Hydrogen in the target/ folder, just copy them all over to your server. As always, don't host your client on the same origin as your homeserver.
Hydrogen aims to be usable as an SDK, and while it is still early days, you can find some documentation how to do that in SDK.md.
