## What it is
Gigablast is a distributed open source web and enterprise search engine with a built-in spider/crawler, written in C/C++ for Linux. It powers gigablast.com and can index and search large collections of web pages across multiple machines.

## Use cases
- run my own web search engine
- crawl and index websites at scale
- self-host an enterprise document search engine
- build a distributed search cluster
- spider the web and build a searchable index
- replace Google with a private search engine

## When to choose
- you need a self-contained, distributed search engine with crawling built in
- you want a proven C++ engine that runs on commodity Linux hardware
- you need to index billions of pages across multiple nodes

## When to avoid
- you just need full-text search over your own data without crawling (use Elasticsearch or Meilisearch)
- you need an actively developed project with a large community
- you need Windows or macOS support

## Facets
- artifact type: application
- maturity: maintenance
- function: search-engine, web-scraping, http-server
- domain: crawlers, developer-tools
- platform: cpp
- tags: distributed-search, web-crawler, spider, enterprise-search, c-plus-plus, search, linux
