Jellyfish is a Python library for approximate and phonetic string matching, offering algorithms like Levenshtein, Jaro-Winkler, Hamming, and phonetic encoders such as Soundex, Metaphone, and NYSIIS. Core algorithms are implemented in Rust for speed, with Python fallback implementations.

Use cases

  • fuzzy match strings in python
  • compute levenshtein distance between two strings
  • phonetic encoding of names for deduplication
  • fuzzy search over a list of names
  • compare misspelled words for spell checking
  • record linkage and entity matching on names

When to choose

  • you need string similarity or phonetic encoding in Python with fast native performance
  • you want a mature, MIT-licensed library with many standard algorithms in one package

When to avoid

  • you need full-text or vector search rather than pairwise string comparison
  • you need fuzzy matching in a non-Python language
