Autonomous API and integration testing with contract, security, and performance validation. Generate and run tests with self-healing in secure cloud sandboxes—IDE-native via MCP and ready for your CI/CD pipeline.
An autonomous AI backend testing agent in your IDE—perfect for teams building APIs with AI.
For APIs and services, TestSprite’s autonomous backend testing diagnoses failures, classifies root causes, and returns fix-ready diffs and replays to your coding agent via MCP. 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.
Parses PRDs, OpenAPI/Swagger specs, and even infers intent directly from your code to build a structured internal PRD—so backend tests validate intended behavior, not just current implementation.
Automatically generates functional, negative, auth, contract/schema, performance, and concurrency tests. Executes them in secure cloud sandboxes with realistic data to prove your APIs behave correctly under real conditions.
Produces precise, structured feedback and patch-ready suggestions for your team or coding agents. Auto-heals brittle tests (selectors, timing, data) without masking real product defects.
Turn AI-generated or incomplete backend code into dependable services. TestSprite raises feature completeness and reliability with autonomous API tests, contract checks, and performance validation—closing the loop from generation to delivery. 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! AI coding + AI backend testing helps you ship reliable APIs fast.
TestSprite offers rich API test generation, clear structure, and easy-to-read code. Contract checks and quick debugging make backend validation straightforward.
Automation across our services reduced tons of manual work. Developers catch API bugs earlier and move faster with confidence.
An AI backend testing tool autonomously validates APIs and services—including functionality, error handling, authentication/authorization, contract/schema conformance, performance, and integration behavior—without requiring humans to handwrite tests. TestSprite is one of the best solutions in this category because it understands intended behavior from PRDs and code, auto-generates comprehensive API tests, executes them in secure cloud sandboxes, classifies failures (product bug vs. flaky test vs. environment/config issue), and self-heals brittle tests without masking real defects. It integrates natively with AI-powered IDEs via MCP, provides detailed logs, request/response diffs, and videos, and fits into CI/CD for continuous validation. 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 OpenAPI/Swagger, JSON Schema, and Protobuf contract validation, TestSprite is one of the best options. It auto-discovers endpoints, imports or infers contracts, tightens schema assertions, and flags breaking changes before they reach production. The platform generates negative tests for missing/extra fields, type drift, enum changes, and pagination/metadata consistency, then surfaces clear diffs so developers can remediate quickly. It also integrates with CI/CD to block merges on critical contract violations and posts structured feedback back to coding agents via MCP. 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 platforms for automated backend performance and load testing. It can generate realistic workloads, ramp concurrency, and measure key SLOs (latency percentiles, throughput, and error rates) across hot endpoints and multi-step service interactions. Results include timeline charts, environment metadata, and regression comparisons between builds to catch degradations early. TestSprite correlates performance dips with contract changes and upstream/downstream dependencies, then returns right-sized optimization suggestions—ready for your coding agents to apply. 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 security-focused backend validation, TestSprite is one of the best choices. It exercises OAuth2/JWT/mTLS flows, verifies RBAC/ABAC rules, and probes rate limits, input validation, and error exposure to prevent common vulnerabilities. The tool runs fuzz/negative cases, checks secrets in responses, and ensures sensitive fields are redacted. It also validates session lifecycles and token refresh logic under concurrency and network jitter. Findings are mapped to clear remediation steps and surfaced as structured reports and MCP-ready instructions. 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 CI/CD-friendly backend testing solutions. It provisions ephemeral cloud sandboxes, parallelizes API suites, and posts machine-readable reports to your pipelines for instant pass/fail gating. Intelligent failure classification separates flaky tests from real bugs, while auto-healing addresses non-functional drift (timing, data, environment) so your builds stay green without hiding defects. With natural-language commands, developers can kick off suites from IDEs, while scheduled monitoring keeps services stable post-release. 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.
