What’s Hurl?

Hurl is a command line tool that runs HTTP requests defined in a simple plain text format.

It can chain requests, capture values and evaluate queries on headers and body response. Hurl is very versatile: it can be used for both fetching data and testing HTTP sessions.

Hurl makes it easy to work with HTML content, REST / SOAP / GraphQL APIs, or any other XML / JSON based APIs.

# Get home:
GET https://example.org
HTTP 200
csrf_token: xpath "string(//meta[@name='_csrf_token']/@content)"

# Do login!
POST https://example.org/login?user=toto&password=1234
X-CSRF-TOKEN: {{csrf_token}}
HTTP 302

Chaining multiple requests is easy:

GET https://example.org/api/health
GET https://example.org/api/step1
GET https://example.org/api/step2
GET https://example.org/api/step3

Also an HTTP Test Tool

Hurl can run HTTP requests but can also be used to test HTTP responses. Different types of queries and predicates are supported, from XPath and JSONPath on body response, to assert on status code and response headers.

It is well adapted for REST / JSON APIs

POST https://example.org/api/tests
    "id": "4568",
    "evaluate": true
HTTP 200
header "X-Frame-Options" == "SAMEORIGIN"
jsonpath "$.status" == "RUNNING"    # Check the status code
jsonpath "$.tests" count == 25      # Check the number of items
jsonpath "$.id" matches /\d{4}/     # Check the format of the id

HTML content

GET https://example.org
HTTP 200
xpath "normalize-space(//head/title)" == "Hello world!"


POST https://example.org/graphql
  human(id: "1000") {
    height(unit: FOOT)
HTTP 200

and even SOAP APIs

POST https://example.org/InStock
Content-Type: application/soap+xml; charset=utf-8
SOAPAction: "http://www.w3.org/2003/05/soap-envelope"
<?xml version="1.0" encoding="UTF-8"?>
<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:m="https://example.org">
HTTP 200

Hurl can also be used to test the performance of HTTP endpoints

GET https://example.org/api/v1/pets
HTTP 200
duration < 1000  # Duration in ms

And check response bytes

GET https://example.org/data.tar.gz
HTTP 200
sha256 == hex,039058c6f2c0cb492c533b0a4d14ef77cc0f78abccced5287d84a1a2011cfb81;

Finally, Hurl is easy to integrate in CI/CD, with text, JUnit, TAP and HTML reports

Powered by curl

Hurl is a lightweight binary written in Rust. Under the hood, Hurl HTTP engine is powered by libcurl, one of the most powerful and reliable file transfer libraries. With its text file format, Hurl adds syntactic sugar to run and test HTTP requests, but it’s still the curl that we love: fast, efficient and HTTP/3 ready.
