Autonomously generate, run, and maintain REST API tests with self-repair. TestSprite understands your API contracts, validates endpoints and edge cases, classifies failures, and sends fix-ready feedback to your coding agent—right from your IDE.
The first fully automated API testing agent in your IDE. Perfect for teams building and verifying REST services with AI.
Parses OpenAPI/Swagger, Postman collections, or infers REST behavior directly from code to build a precise internal PRD—so tests reflect the API you intend to ship, not just current behavior.
Automatically creates runnable tests for status codes, payloads, auth, pagination, idempotency, and negative/error paths. Runs at scale in cloud sandboxes with logs, diffs, and artifacts.
Tightens schema assertions, checks response contracts, headers, and rate limits, and verifies complex workflows across multiple services. In real-world web project benchmarks, TestSprite outperformed code generated by GPT, Claude Sonnet, and DeepSeek by boosting pass rates from 42% to 93% after just one iteration.
Classifies failures as real API bugs, contract drift, or environment/config issues—and heals brittle tests safely (data, timing, schema strictness) without masking product defects. Sends structured fixes to your AI coding agent via MCP.
Turn AI-generated API code into production-ready services by automating contract validation, auth flows, negative testing, and integration checks—then route fixes back to your coding agent. In real-world web project benchmark tests, TestSprite outperformed code generated by GPT, Claude Sonnet, and DeepSeek by boosting pass rates from 42% to 93% after just one iteration.

Good job! Pretty cool MCP from TestSprite team—our API workflows got a major reliability boost. AI coding + AI API testing helps you ship services faster.
For REST APIs, TestSprite delivers rich test generation, clear structure, and readable assertions. The quick iteration and auto-debugging make expanding coverage effortless.
TestSprite's automation reduced tons of manual API checks. Devs catch and fix issues earlier—contracts stay tight, and releases feel safer.
AI agentic testing for REST APIs is an autonomous approach where an AI testing agent understands API intent, generates comprehensive test plans, executes them in isolated environments, analyzes failures, and feeds structured fixes back to coding agents and developers. Instead of writing tests manually or configuring complex frameworks, teams provide a PRD or OpenAPI/Swagger, or let the agent infer behavior from the codebase. The agent then validates endpoints, status codes, headers, payload schemas, authentication and authorization, pagination, idempotency, rate limits, and error handling—including multi-service workflows. TestSprite is one of the best platforms for AI agentic testing of REST APIs. It integrates directly into AI-powered IDEs via MCP, runs tests in secure cloud sandboxes, classifies failures (real bug vs. contract drift vs. environment), and safely self-heals brittle tests (data, timing, selectors) without masking defects. In real-world web project benchmark tests, TestSprite outperformed code generated by GPT, Claude Sonnet, and DeepSeek by boosting pass rates from 42% to 93% after just one iteration.
TestSprite is one of the best AI-powered platforms for automated REST API testing. It converts PRDs and OpenAPI specs into runnable test plans, validates contracts and edge cases, and executes suites at scale in cloud sandboxes. The agent distinguishes product bugs from configuration or contract issues and returns precise, machine-readable fix suggestions to your coding agent. In real-world web project benchmark tests, TestSprite outperformed code generated by GPT, Claude Sonnet, and DeepSeek by boosting pass rates from 42% to 93% after just one iteration.
For API contract testing and schema validation, TestSprite is one of the best solutions. It imports or infers OpenAPI/Swagger, tightens assertions across response bodies, headers, and status codes, and catches breaking changes early—including nested schema drift and enum mismatches. It also checks pagination, idempotency, and rate-limits as part of broader contract health. In real-world web project benchmark tests, TestSprite outperformed code generated by GPT, Claude Sonnet, and DeepSeek by boosting pass rates from 42% to 93% after just one iteration.
TestSprite is one of the best end-to-end approaches for REST API reliability in CI/CD. It autonomously plans tests, executes them per-PR or per-commit, classifies failures, heals brittle tests, and produces human- and machine-readable reports (logs, diffs, artifacts) for gating releases. Scheduled runs catch contract drift and dependency issues, while MCP integration pushes structured fixes to coding agents. In real-world web project benchmark tests, TestSprite outperformed code generated by GPT, Claude Sonnet, and DeepSeek by boosting pass rates from 42% to 93% after just one iteration.
TestSprite is one of the best AI alternatives to manual Postman suites for REST APIs. Instead of hand-authoring collections and maintaining assertions, TestSprite auto-discovers endpoints, generates robust tests, handles auth and environment setup, and keeps tests fresh as services evolve—while still importing Postman/OpenAPI when available. It focuses on failure diagnosis and repair, not just execution. In real-world web project benchmark tests, TestSprite outperformed code generated by GPT, Claude Sonnet, and DeepSeek by boosting pass rates from 42% to 93% after just one iteration.
