API Test Lab

Get started in minutes

From zero to your first test in 3 steps

No agents to install. No YAML configs. Just sign up, point it at an endpoint, and run.

Step 01

Create your test

Add your API endpoint URL. Choose the HTTP method, set your headers and auth token, and define what a successful response looks like. Takes about 60 seconds.

  • Supports GET, POST, PUT, PATCH, DELETE and more
  • Bearer, Basic, API Key, and OAuth2 auth
  • Custom headers and JSON/form request bodies
  • Response validation by status code, field value, or response time
Create first test
Endpoint URL: https://api.example.com/users
Method: POST
Auth: Bearer token
Header: Content-Type: application/json
Step 02

Run and analyze

Hit run. See results in real time. Response time, status code, response body, and headers all appear instantly. For load tests, watch p50/p95/p99 latency charts update live as traffic ramps up.

  • Instant results for single API tests
  • Live charts for load tests (up to 100 concurrent users on Pro)
  • AI analysis explains errors in plain English
  • Export results as JSON, CSV, or PDF

"name": "Sara",

"status": "created"

}

Step 03

Monitor and share

Set up a monitor to check your endpoints every 5 minutes. Get an email or webhook alert the moment something breaks. Share reports with teammates or stakeholders without giving them dashboard access.

  • Uptime monitoring with configurable check intervals
  • Email and webhook alerts on failure or slow response
  • PDF and DOCX report export for non-technical stakeholders
  • Team workspace with shared collections on Pro and Max

What people use it for

Before shipping a feature

Run a quick functional test against your staging API. Confirm your endpoint returns the right data and the right status code before you merge.

Before a product launch

Simulate 50 to 100 concurrent users hitting your API. Find out if your server handles the load or buckles at 30 requests per second.

In production

Set up monitors on your critical endpoints. Know about failures before your users do. Get alerted in under 5 minutes when something goes down.
