    With Google Translate, we can translate any language to any language. Apertium only allows the translation of specific languages to other specific ones. Eg.: Portuguese to only Catalan, Spanish and Galician, but not English, French or German like Google Translate does.

    GPLed, free-libre open-source software. So, not ending in the same problems as with Google (which is the case for DeepL).

    Wiktionary vs Google Translate opinions
    This alternative is disputed. Wiktionary is still a legitimate alternative to Google Translate, but it might have issues that some users think are important.

    All in one dictionary with references in all other languages including old and rare ones.

    It's not a translator, but if you used google translate to translate single words into other languages instead of whole sentences, it works just fine as an alternative.
