For translations which is the simplest tool.
Do you mean, a tool to add translated names for OSM items?

IMHO the
OSM.org editor (iD) is simple enough, for casual editing. If
you're looking for mass additions, it might be useful to look for
alternative methods: for instance, maybe it's comparatively easy to
patch the tile generator so that it fetches alternative names from
Wikidata when connected?
