easy to use, easy to update.

Does the thunderstore launcher install bepinX or I have to do it manually like with Vortex?

(I know it's easy, but i'm a special kind of lazy)

no it does not, you have to find it and download it as well, but Thunderstore also can grab dependencies. its simple to use.

I prefer to use r2modman[valheim.thunderstore.io] (found, somewhat ironically, through the Thunderstore website) when doing modded maps. It's more-or-less Thunderstore's mod manager, but without third-party overhead. Also automatically locates and installs dependencies on your mods (so you don't have to go after BepinEx itself - if one of your mods needs it to run, the manager will download and install it for you), though that really seems to come down to Thunderstore apparently being better at keeping track of such things for the mods they host.

EDIT: And I see sarteck managed to ninja me on mentioning r2mm (and providing a better overview of what you can do with it).
