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
