## What it is
DotnetSpider is a .NET Standard web crawling and scraping framework that is lightweight, efficient, and cross-platform. It supports distributed crawling with pluggable storage backends like MySQL, Redis, PostgreSQL, MongoDB, and RabbitMQ.

## Use cases
- scrape data from websites in .NET
- build a distributed web crawler in C#
- extract structured data from web pages
- schedule recurring web scraping jobs
- crawl sites and store results in a database
- collect data for downstream analytics pipelines

## When to choose
- you are building scrapers in C#/.NET and want a high-level framework
- you need distributed crawling with queue and storage integrations
- you want cross-platform crawling on .NET Core

## When to avoid
- you work primarily in Python (Scrapy may fit better)
- you only need a one-off simple HTTP fetch
- you need a headless-browser-first scraping solution

## Facets
- artifact type: framework
- maturity: active
- function: web-scraping, etl, parser, http-client
- domain: crawlers
- platform: cross-platform, dotnet
- tags: crawler, distributed-crawling, csharp, scraping, data-engineering, automation, docker
