uFuzzy is a tiny (~7.5KB), zero-dependency JavaScript fuzzy search library for matching a short needle phrase against large lists of short-to-medium haystack strings. It supports out-of-order term matching, typo tolerance, substring exclusions, and exact terms, with no index to build and fast, low-memory searching.

Use cases

• filter a large list as the user types
• add autocomplete or typeahead suggestions to a search box
• fuzzy search filenames, titles, or function names
• tolerate single typos in user search queries
• search with out-of-order terms like 'spac ca'
• exclude substrings from search results like 'fruit -green'

When to choose

• you need fast client-side fuzzy filtering of in-memory string lists
• you want predictable, explainable ranking instead of a black-box relevance score
• startup time and memory footprint matter and building a search index is overkill
• you want a tiny dependency-free library for autocomplete or list filtering

When to avoid

• you need full-text search over large document collections with relevance scoring
• you need Unicode/CJK-heavy text matching out of the box
• you need a server-side search engine with indexing, stemming, or faceting
