## What it is
Livegrep is a tool for interactive regex search over gigabyte-scale source code repositories, inspired by Google Code Search. It consists of a codesearch backend that indexes and searches code over gRPC, and a stateless web frontend.

## Use cases
- search regex across large monorepos interactively
- self-host a code search server for my organization's repositories
- index gigabyte-scale source code for fast lookup
- grep source code from a web browser
- build a reusable code index file for offline searching

## When to choose
- you need fast interactive regex search over very large codebases
- you want a self-hosted code search service with a web UI
- you need index files that can be reused without access to the original repos

## When to avoid
- you only need simple grep on a small codebase
- you want semantic or symbol-aware code navigation rather than regex search
- you cannot build C++ projects with bazel
