Hurl is a command-line tool that executes HTTP requests defined in straightforward plain text format. It enables developers to chain requests, capture response values, and validate headers and body content with powerful query capabilities.

The tool works with HTML content, REST/SOAP/GraphQL APIs, and any XML/JSON-based services. Whether you're fetching data or running comprehensive HTTP test suites, Hurl provides a lightweight, efficient solution.

Key capabilities include:

Request chaining - Execute multiple requests in sequence with captured values flowing between them
Response assertions - Validate status codes, headers, body content using XPath, JSONPath, and regex patterns
Multiple API types - Native support for REST, GraphQL, SOAP, and standard HTTP/XML/JSON APIs
Form and file handling - Submit form data, multipart uploads, and binary files
Authentication - Built-in BasicAuth, cookies, and custom headers
Performance testing - Measure response duration and validate speed requirements
Retry logic - Automatic retry with configurable intervals for polling operations
CI/CD integration - Generate text, JUnit, TAP, and HTML reports for pipeline automation

Written in Rust and powered by libcurl, Hurl delivers fast execution, IPv6 support, and HTTP/3 compatibility. The single binary installation requires no runtime dependencies, making it ideal for both local development and continuous integration environments.
