What is good for spell checker? Google spell checker or Hunspell

问题

For my asp.net website, I need spell check functionality. I found some interesting solutions to do it.

1. Google spell checker
2. Hunspell.
Both are free. For my understanding I realized some cons and pros for both approach.

For Google spell checker, it gives much more correct word for incorrect word but Hunspell gives several suggestions. And Google has up to date suggestions but Hunspell,it depends on Open Office dictionary.

In my case, I need only one suggestion. For cons, I have to depend on Google for spell checking. If Google service is down, it will effect for my site too.

So, what will be suitable for my site. Is it good idea to choose Google spell checker? Is there are any non free solutions for spell checking?

I think, it's good to use Hunspell

Reason for using Hunspell

NHunspell is based on Hunspell and brings the Open Office spell checking, hyphenation and thesaurus to the Microsoft® .NET Framework. NHunspell is a .NET (C#, VB) library and wraps the native libraries Hunspell, Hyphen and MyThes.

The integrated libraries are used in OpenOffice and work with the dictionaries published on OpenOffice.org.

NHunspell is licenced under: GPL/LGPL/MPL. Free use in commercial applications is permitted according to the LGPL and MPL licenses. Your commercial application can link against the NHunspell DLLs.
