>https://languagetool.org https://languagetool.org for sure. Europe-based, can host your own server. Plus, it's the only one that doesn't seem to eat my Mac's battery. >Some (might be all, actually?) parts are open source as well. I was pretty impressed with languagetool and set up my own server (as I'm not interested in sharing with random strangers). I used it for a while (local server, Firefox addon), but haven't used it for a while. Yesterday I noted that the Firefox addon was chewing a goodly portion of CPU (perhaps because the local server is down?). As such, I removed the addon and won't be going back -- not because languagetool is bad, it works quite well actually -- but because it didn't add enough value to me (note that only applies to me) to make the CPU load worthwhile. That said, I heartily recommend self-hosted implementations of languagetool!
