Searches eleven English–Ukrainian dictionaries at once, including technical ones.
Details
A volunteer project that queries around a dozen English-Ukrainian dictionaries simultaneously and shows the results side by side, which is genuinely useful when a word has several plausible translations and you want to see which sources agree. It leans scholarly and includes specialised and technical vocabularies you will not find in app dictionaries. The sister site r2u.org.ua does the same for Russian-Ukrainian and hosts a spelling checker. Free, but the interface is utilitarian and Ukrainian-only.
