AI companies typically use a mix of crawl, scrape, and index tools to collect web data. The exact stack varies, but common categories include:
1. Web crawlers
These automatically discover and fetch pages across the web.
- Scrapy — popular open-source crawling framework
- Apache Nutch — large-scale crawler
- Heritrix — archival-grade web crawler
- Custom crawlers — many companies build their own for scale and control
2. Scraping tools
These extract content from pages after they’re fetched.
- Beautiful Soup — HTML parsing
- lxml — fast HTML/XML parsing
- Playwright — browser automation for dynamic sites
- Selenium — browser automation, especially for JavaScript-heavy pages
- Puppeteer — Chrome automation
3. Data pipeline and ETL tools
Used to clean, deduplicate, filter, and normalize collected web data.
- Apache Spark
- Apache Beam
- Airflow
- Kafka
- Custom data processing systems
4. Web archives and datasets
Companies also license or ingest existing large web corpora.
- Common Crawl
- Wikipedia dumps
- Internet Archive
- Public domain or licensed datasets
5. Search/index infrastructure
Used to store and query the collected content.
- Elasticsearch
- OpenSearch
- Solr
- Vector databases for downstream retrieval
6. Anti-bot and rendering infrastructure
Because many sites block automated access, companies often use:
- Headless browsers
- Rotating proxies
- IP reputation management
- CAPTCHA solving services, sometimes
- Rate limiting and politeness systems
7. Internal proprietary systems
Large AI labs often use custom systems for:
- Large-scale crawling
- Deduplication
- Quality scoring
- Language detection
- Content classification
- Policy/compliance filtering
