Ensure your API works.

Correctly. Always.

Skybear.NET is a managed platform automating Synthetic HTTP API testing.

DEMO — Show! Don't tell.

Just the tip of the iceberg. From basic tests to multi-step user journeys.

Test authentication protected APIs

GET https://www.skybear.net/_live-demo/secure.json
HTTP 403

GET https://www.skybear.net/_live-demo/secure.json
Authentication: Bearer sample-token-123
HTTP 200
[Asserts]
body == "{\"ok\":true}"
jsonpath "$.ok" == true

JSON response assertions

GET https://www.skybear.net/_live-demo/sample-001.json
HTTP 200

[Captures]
contentType: header "Content-Type"

[Asserts]
# Assert headers.
header "content-type" endsWith "/json"
# Assert variables captured from previous responses.
variable "contentType" endsWith "/json"

# Assert the body as JSON!
jsonpath "$.projects.[0].points" == 2
jsonpath "$.projects.[0].points" isNumber
jsonpath "$.address.street" split " " nth 1 == "Maple"

# Assert the body as raw bytes or plain text!
bytes count < 1000
body contains "Maple"

Assert round-trip latency is low

GET https://www.skybear.net/_live-demo/get.json
HTTP 200

[Asserts]
# Roundtrip should be less than 1 second.
duration < 1000

Basic uptime healthcheck

GET https://www.skybear.net
HTTP 200

Multi-step workflow

# Create a workflow calling multiple remote APIs.
GET https://www.skybear.net/_live-demo/get.json
HTTP 200

[Captures]
var1: jsonpath "$.var1"

# Use captured value from previous response.
POST https://www.skybear.net/_live-demo/set/{{ var1 }}
HTTP 200

# Just send requests, without asserting the response.
POST https://www.skybear.net/_live-demo/set/call-two
POST https://www.skybear.net/_live-demo/set/call/three

As a maintainer of Hurl, I've been really curious about this product (while not affiliated at all)! It has been an interesting journey because I've seen how you can build something like this: first you start with a solid first simple iteration (just an editor of web script files), then slowly you add features around it and expand: a very good documentation, "cron" scripts, email alerts etc...

I'm using Skybear.net at work today to do web sites monitoring (SSL certificates and health check), simple but very effective... impressive for a one man work!

Ensure Every Detail: Comprehensive Assertions Made Easy.

Tired of subtle bugs slipping through? Hurl provides comprehensive assertion utilities to ensure the response is exactly what you expect. Easily verify HTTP response headers and bodies (including JSON, XML, HTML).

Hurl predicates, filters, and exact matching capabilities for powerful assertions — **Just a glimpse** of Hurl captures, predicates, filters, and exact matching capabilities for powerful assertions.

Assert your API responses

After signing up, we will automatically create a script with a variety of assertions for you to edit.

Automate Continuous Monitoring & Ditch Manual Checks.

Schedule your API tests to run automatically at any interval. Get alerted to issues with cron triggers before they impact your users. Perfect for health checks, data validation, and ensuring critical endpoints are always responsive.

Configure your scripts to run periodically with scheduled cron triggers. — Configure your Skybear.NET scripts to run periodically with scheduled cron triggers.

Integrate API Testing into Your CI/CD Pipeline.

Catch breaking changes before they hit production. Use Skybear.NET as a validation step in your CI. Invoke your scripts from anywhere using HTTP Hook triggers and we will run them for you.

# Runs your script, stores the report, returns the results.
curl -X POST \
-H "Content-Type: application/json" \
-d '{"hurlVariables":{"BASEURL": "example.com"}}' \

Test Entire User Journeys & Complex API Interactions.

Simulate real user behavior by codifying entire user journeys. Write powerful multi-step tests with ease, executing hundreds of requests in a single, easy-to-read Hurl script.

Avoid the complexity and cost of other tools as your testing needs evolve.

Create a multi-step API test

After signing up, we will automatically create a script with multiple requests chained for you to edit.

Automate & Orchestrate Any HTTP API Workflow.

Need to chain calls between different services or automate repetitive HTTP tasks? Skybear.NET scripts are perfect for multi-step workflows.
Orchestrate requests across any HTTP API (REST, GraphQL, JSON, XML, and more) with simple, maintainable scripts.
