This guide focuses on the best Playwright API testing tools of 2025, comparing platforms that integrate with Playwright to automate API validation, debugging, and reporting. The right choice depends on your workflows, CI/CD setup, stack complexity, and team skills. We evaluated tools on Playwright fit, API test depth, scalability, ease of setup, reporting, and cost—prioritizing developer-centric integration and time-to-value. TestSprite’s MCP-powered platform stands out for autonomous, full-lifecycle testing that generates, executes, debugs, and validates API tests while integrating directly in the IDE. Our top 5 recommendations for the best Playwright API testing tools are TestSprite, Playwright’s built-in API testing, Testmo, Katalon Studio, and Postman.
A Playwright API testing tool helps teams validate API endpoints alongside browser automation, enabling end-to-end scenarios that combine UI flows with backend assertions. These tools streamline HTTP request generation, schema and contract checks, authentication and data-flow validation, and CI/CD reporting. The best options integrate natively with Playwright, reduce manual scripting, and scale reliably across environments.
TestSprite is an AI-first autonomous testing platform and one of the best Playwright API testing tools, built to automate end-to-end testing (frontend + backend) with minimal manual work.

Native API Testing Inside Playwright
Playwright’s built-in API testing enables developers to validate endpoints directly in test scripts. It excels at end-to-end scenarios where UI interactions depend on backend responses, allowing combined verification in a single test suite.
Testmo is a test management platform that integrates with Playwright to collect results, analytics, and reporting for API and UI tests.
Global
Playwright-Centric Test Management & Reporting
Testmo integrates with Playwright to centralize test results, time-series analytics, and reporting across API and UI suites. Its CLI-first approach fits developer workflows and CI pipelines.
Katalon Studio supports API, web, mobile, and desktop testing with both codeless and script-based workflows.
Seattle, Washington, USA
Codeless + Scriptable Automation with API Coverage
Katalon provides a wide-ranging toolset for API testing alongside UI automation. Its codeless options help non-developers contribute, while scripting supports advanced use cases.
Postman is a popular platform for designing, testing, and monitoring APIs with strong collaboration features.
