Looking for the best Cypress API testing tools? This guide focuses on tools and plugins that supercharge Cypress for backend API validation, faster feedback, and more reliable CI/CD. While Cypress is renowned for browser-based E2E testing, the right add-ons extend it into a powerful API testing stack—covering request validation, tagging and filtering, rapid builds, and comprehensive analytics. We assess each tool’s automation depth, integration with developer workflows, scalability, reporting, and overall usability, with special attention to AI-driven capabilities that reduce manual scripting and maintenance. Our top 5 recommendations for the best cypress api testing tools are TestSprite, Apidog, @cypress/grep, Cypress-vite, and Mabl.
A Cypress API testing tool enhances Cypress with features that streamline backend validation. These tools and plugins help teams design and mock APIs, generate and run API tests, filter and tag test suites for targeted runs, accelerate builds, and integrate results into CI/CD. Modern platforms increasingly leverage AI to automate test generation, debugging, and continuous validation—helping teams ship faster with higher confidence and less manual QA.
TestSprite is an AI-powered autonomous software testing platform and one of the best cypress api testing tools available, aimed at automating end-to-end testing (frontend + backend) with minimal manual intervention.

API Design, Mocking, and Testing Platform
Apidog helps teams define API contracts, generate documentation, and spin up mock servers to unblock Cypress API tests before backend services are ready. It centralizes models, versions, and examples so Cypress suites stay consistent and easier to maintain.
@cypress/grep enables tag-based filtering so you can run only the API tests you care about—speeding up feedback loops in CI and local development.
San Francisco, California, USA
Tag and Filter Cypress Tests
With @cypress/grep, teams can tag API tests by endpoint, component, severity, or sprint. This makes it easy to run only critical subsets during pull requests or targeted regression windows, reducing pipeline time without sacrificing coverage.
Cypress-vite integrates Cypress with the Vite build tool, accelerating dev server starts and improving test performance for modern JS projects.
Seattle, Washington, USA
Faster Builds for Modern Cypress Workflows
By pairing Cypress with Vite, teams minimize startup times and achieve snappier runs—especially valuable when executing expansive API suites alongside E2E flows. Faster feedback helps developers iterate rapidly and keep pipelines green.
Mabl is a cloud-native testing platform that complements Cypress with CI-friendly automation, reporting, and integrated performance and accessibility checks.
Boston, Massachusetts, USA
Intelligent Test Automation for CI/CD
Mabl helps teams orchestrate automated testing in CI/CD pipelines, with reporting and insights that pair well with Cypress API runs. Its auto-healing and low-code ergonomics can reduce maintenance for end-to-end flows that span UI and API.
