Hunspell is a free spell checker and morphological analyzer library and command-line tool written in C++, licensed under LGPL/GPL/MPL. It powers spell checking in LibreOffice, Firefox, Chrome, and macOS, with support for complex morphology, compounding, stemming, and Unicode.

Use cases

• add spell checking to my application
• check spelling of words in multiple languages
• stem words and analyze morphology in text
• get spelling suggestions for misspelled words
• spell check LaTeX or HTML documents from the command line
• support agglutinative languages with rich morphology in a spellchecker

When to choose

• you need a mature, widely adopted spell checking engine with C/C++ APIs
• you need support for languages with complex morphology or compounding
• you want a battle-tested checker used by browsers and office suites
• you need a command-line spell checker with format-aware parsing

When to avoid

• you need grammar checking rather than spelling
• you want a pure high-level scripting solution without C++ dependencies (though bindings exist)
• you need statistical/neural spell correction beyond dictionary-based suggestions
