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}"

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

The Skybear.NET open editor doesn't need an account and can be used for quick adhoc testing.

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!

You want your API to be online, and correct, right?

Focus on shipping features, and let Skybear.NET validate that your API works as expected. Codify requests and verify the responses.

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

Create your first test script

After signing up, we will automatically create a script for you to edit.

Do you need exhaustive assertions?

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.

Tired of manual checks? Need reliable continuous monitoring?

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

Do you want to validate deployments before breaking 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"}}' \

Codify entire user journeys for complete testing?

Write powerful multi-step tests with ease, executing hundreds of requests within a single script.

Stop using tools that become increasingly complex and expensive as your needs grow.

Create a multi-step API test

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

Just want to automate and orchestrate a bunch of HTTP APIs?

Skybear.NET scripts are perfect for multi-step workflows too.
Orchestrate requests across any HTTP API (REST, GraphQL, JSON, XML, HTTP, more).

# Create a workflow calling multiple remote APIs.

Orchestrate an HTTP workflow

After signing up, we will automatically create a script workflow for you to edit.

What's that? You prefer running and iterating on your scripts locally?

Run your Hurl scripts locally using the powerful Hurl command line tool.

hurl --report-json out/ demo.hurl
