junegunn/fzf

This is a high-performance fuzzy finder and general-purpose interactive filter, rewritten in Go to replace a previous Ruby implementation. It provides a modern terminal user interface with advanced rendering, mouse support, and ANSI escape sequence parsing. The system includes shell integration for Bash, Zsh, Fish, and Nushell, along with a Vim plugin and tmux helper scripts for seamless workflow integration. It also features optimized fuzzy matching algorithms and security hardening via OpenBSD pledge.

About this page

  • The description of this project is derived from its own commit history, not from its README.
  • The score is its highest published measurement, taken on 1 August 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
  • Measured at commit 3337be9d45 — the exact code this score is about.
  • Scored under rubric rubric-2026.08.18. Score the same commit under that rubric and you get the same number.
