About Keploy

Keploy is an AI-driven testing platform that automates the generation of test cases for APIs and applications by capturing real application data during runtime. It eliminates the need for manual scripting by automatically creating accurate test cases from live traffic, allowing developers and DevOps teams to validate functionality efficiently. The platform integrates smoothly into existing workflows, including CI/CD pipelines, to enable continuous testing and early detection of bugs. It supports a wide range of applications and frameworks, making it suitable for teams focused on improving software quality while reducing the time spent on repetitive testing tasks. Keploy also provides insights into redundant tests and edge case failures, helping teams streamline their testing processes and enhance overall reliability. By leveraging captured data, it ensures that tests reflect actual usage patterns, leading to more reliable and maintainable software. The tool is designed to be developer-friendly, offering features that simplify test maintenance and accelerate feedback loops in the development lifecycle.

Frequently asked questions about Keploy

Is Keploy an API testing or integration testing tool?

Keploy supports both API and integration testing. It generates API tests from traffic, specifications, and application context, while its record-and-replay platform creates integration and regression tests with virtualized databases, queues, APIs, and other dependencies.

How does Keploy work, and does it require code changes?

Keploy captures incoming requests and outgoing dependency calls using eBPF and network-level interception without requiring application code changes. It converts the captured behavior into editable tests and mocks, then replays them against new builds to catch regressions.

How does Keploy improve test coverage from real traffic?

Keploy converts actual requests, responses, dependency interactions, and data states into reproducible tests. It uses API schemas and application context to generate additional edge cases, connected flows, and scenarios beyond the original recordings.

How is Keploy different from Postman and traditional mocking tools?

Postman is used to design and manually test API requests, while tools like WireMock require developers to define and maintain mocks. Keploy generates tests and dependency mocks from real application behavior, including calls to databases, queues, caches, and external APIs.

Can Keploy verify AI-generated code and run in CI/CD?

Yes. Keploy lets developers and coding agents test changes against recorded application and dependency behavior. Tests can run locally or in CI/CD pipelines to detect response, schema, contract, and performance regressions before code is merged or deployed.

Is Keploy open source, and does it support Kubernetes?

Keploy's core local record-and-replay platform is open source under the Apache 2.0 license. Enterprise capabilities include recording from Kubernetes, staging, and production environments, along with governance, security controls, dashboards, and support.
