FFF is a fast, typo-resistant file and content search toolkit written in Rust, available as an SDK for Rust, C, Python, Bun, NodeJS, and Lua, plus an MCP server for AI agents. It provides frequency-ranked file access, a background watcher, and an in-memory content index, and originated as a popular Neovim plugin.

Use cases

• fast fuzzy file search in neovim
• give AI agents fast file search via MCP
• search files with typo tolerance in a long-running process
• index file contents in memory for quick grep-like search
• embed file search into a Rust or Python application
• replace fzf and ripgrep roundtrips in editors and shells

When to choose

• you need repeated file searches in a long-running process where spawning ripgrep/fzf each time is too slow
• you want typo-resistant, frequency-ranked file finding
• you're building an AI coding agent or editor that needs fast file search
• you use Neovim and want a fast fuzzy file finder

When to avoid

• you only need a one-off grep or find from the shell
• you need full-text search over huge document corpora rather than code files
• you need a GUI file search tool
