AgentQL

AI-powered query language for web data extraction – write natural language queries to extract structured data from any webpage.

Each tool is evaluated against our methodology using public docs, vendor demos, and hands-on testing.

Agentic extraction tools use AI models (often vision-language models) to autonomously understand and interact with web pages. Instead of writing CSS selectors or XPath queries, you describe what data you want in natural language and the AI figures out how to get it. This approach is more resilient to website changes and can handle complex, multi-step extraction workflows.

Editorial assessment

The query language approach is a clever middle ground between CSS selectors and full natural language – more precise than prompts, more flexible than XPath. Still building mindshare in a category with many competitors. The custom query language adds a learning curve that pure natural language tools avoid. Best for teams wanting structured precision.

How AgentQL compares

ScrapeGraphAI

ScrapeGraphAI uses pure natural language prompts, lower learning curve but less precision.

Diffbot

Diffbot auto-detects structure without any query language, but at enterprise pricing.

Stagehand

Stagehand's act/extract/observe API is simpler for TypeScript developers building agent workflows.
