About fff

A file search toolkit for humans and AI agents. Really fast. Typo-resistant path and content search, frequency-ranked file access, a background watcher, and a lightweight in-memory content index. Way faster than CLIs like ripgrep and fzf in any long-running process that searches more than once. Powers file search in opencode, nushell, and many more amazing projects! Originally started as Neovim plugin people loved, but it turned out that plenty of AI harnesses and code editors need the same thing: accurate, fast file search as a library. That is what fff is.
