What hackers pick instead
- ripgrepA much faster grep replacement for searching codebases, also widely used by AI coding agents; the main caveat is its default skipping of gitignored and hidden files.122recommend
- ast-grepA syntax-aware command-line tool for searching and refactoring code without regex headaches, which people also expose to AI agents as a skill. Some report mixed results.21recommend
- SembleDevelopers recommend Semble for fast local code search that needs fewer tokens and queries than grep. Critics question how the token savings are measured.20recommend
- Graft (Claude Code hooks)People recommend it for giving coding agents a map of the code that searches inside files rather than by names, cutting tokens and latency. Critics say the benchmarks are thin and the README reads as generated.13recommend
- Lat.mdRecommended as a Markdown knowledge graph that helps AI agents search code faster than grep. Main caveat: critics want proof of better performance.11recommend

For the performance improvements when reading files.

results in better results to me, but even that is debatable
Recommends · Jul 2026 · in “Stop Using OpenCode”
They have prebuilt binaries now for fff
Recommends · Feb 2026 · in “Fff.nvim – the first ever typo resistant code search”
But not a plain binary, which is the main way ripgrep is directly used (...at least by humans), and compared with.
