I want a heuristic grammar checker, but obviously don’t want to use Grammerly. Is there an open source alternative that can compete in the depth of corrections provided, and preferably does its processing locally, which Grammerly doesn’t?

    LanguageTool is at least partially open source.
    You can use it with their server or run it on your own machine.

    Their Browser extension used to be open source, but their new one isn’t any more.

    I used LanguageTool for a while with firefox. First, I tested it by running a service locally, but I noticed that with time it used more and more RAM and I had to restart once in a while. But then I moved it to the cheapest instance on DigitalOcean, and it’s running fine so far. I’m assuming it’s the Java garbage collector that just didn’t bother to clean up if it had more RAM available. Not sure, maybe it can be configured but I didn’t look into it.

    Other than that, I pretty much liked it. It’s pretty easy to self-host, and you can also use it in google docs documents if you use that.

    In addition to LanguageTool, you can also check out RedPen. Be warned; it has a lot of false positives, and isn’t very intelligent.

    grammar checker is one the best alternative of grammarly. I personally use this site and it help you to find your grammar, spelling mistakes.
