All-in-one platform

API Testing Platform

An API testing platform combines request building, load testing, traffic monitoring, and AI analysis in one workspace—so your team is not juggling a client, a script runner, and a separate monitor.

  • Functional REST testing in the browser
  • No-code load tests with live latency charts
  • Traffic monitoring for production endpoints
  • AI insights for slow or failing responses

Free tier available. No credit card required to start.

What is an API testing platform?

A single-purpose tool might only send HTTP requests. An API testing platform covers the full loop: validate contracts, stress endpoints under load, watch production traffic, and explain failures—without switching products.

  • One account for testing, load, and monitoring
  • Shared collections and environments for teams
  • Free tier to start; Pro from $5/month
  • No desktop install or credit card for free use

Request builder that stays out of your way

Compose GET, POST, PUT, PATCH, and DELETE requests with headers, query params, JSON bodies, and auththen inspect status, timing, and formatted JSON responses.

  • Bearer, API key, and Basic auth in the UI
  • Environment variables for staging vs production
  • Save requests into collections and folders
  • Export as cURL, Python, or fetch snippets

Load testing and monitoring in the same workspace

After functional checks pass, stress-test endpoints and monitor real trafficwithout switching to another product.

  • No-code load tests with live charts
  • Traffic monitor script for production sites
  • AI explanations for slow or failing APIs
  • Free tier to start; Pro from $5/month

From solo debugging to team workflows

Organize APIs into collections, share folders with teammates, and re-run the same requests after every deploy.

  • Collections and folder tree in the Test Lab
  • Import OpenAPI specs to bootstrap collections
  • Workflows to chain requests in order
  • History of runs with response previews
