Keploy vs OpenMark AI

AI-Powered Test & Mock Generation

Keploy uses advanced AI to automatically create stable, deterministic test cases and mocks by analyzing real API traffic. Instead of you writing countless lines of test code, it intelligently records live application behavior and transforms it into a comprehensive test suite. This includes generating precise stubs for databases, external services, and other dependencies, ensuring your tests run in a perfectly isolated sandbox every time.

Record and Replay API Traffic

This is Keploy's foundational feature. Using eBPF, it non-intrusively records all API calls and network interactions made by your application during normal operation or specific testing sessions. You can then replay these recordings as automated tests in your CI/CD pipeline. This ensures your tests are based on real-world usage patterns and data, making them far more relevant and reliable than manually scripted scenarios.

Coverage and Performance Reporting

Keploy doesn't just create tests; it gives you clear visibility into their effectiveness. It provides detailed coverage reports, showing exactly which parts of your codebase are exercised by your tests. Furthermore, it offers performance testing capabilities by analyzing the recorded traffic, helping you identify potential bottlenecks and ensure your application meets performance standards from the very beginning.

Seamless CI/CD and Developer Tool Integration

Built for developer workflow efficiency, Keploy integrates directly into your existing tools. It works natively with popular CI/CD platforms, automatically running the generated test suite on every pull request or build. For developers, there's also a dedicated VS Code extension, allowing you to generate, manage, and run tests directly from your IDE, making test creation a natural part of the coding process.

Intuitive Task Description

OpenMark AI allows users to describe their benchmarking tasks using simple language. This user-friendly approach eliminates the need for technical jargon, making it accessible for teams of all skill levels. You can easily set up your desired tests without extensive prior knowledge.

Real-Time Model Comparison

The platform facilitates real-time comparisons of over 100 models, allowing you to run benchmarks across various tasks simultaneously. This feature provides immediate insights into which model performs best for your specific requirements, ensuring that you select the most suitable option for your needs.

Cost Efficiency Tracking

OpenMark AI emphasizes understanding the real costs associated with API calls. It provides detailed insights into the cost per request, helping users identify the best model that balances quality and affordability. This feature is particularly useful for teams looking to optimize their budgets while achieving high-quality outputs.

Consistency Checks

The platform includes tools to verify the consistency of model outputs across repeated runs. This is crucial for applications where reliability is key. By assessing how models perform under the same conditions multiple times, users can ensure that the selected model meets their stability requirements.

Accelerating Legacy Application Testing

Modernizing or adding tests to a large, untested legacy codebase is a daunting task. Keploy can be attached to the running application to record its real traffic. Within minutes, it generates a full suite of integration and API tests that reflect how the application is actually used, providing immediate test coverage and a safety net for future refactoring or feature development.

Ensuring Reliability in Microservices Architectures

Testing microservices is complex due to numerous interdependent services. Keploy simplifies this by recording interactions between services during development or staging deployments. It automatically creates mocks for each service, allowing teams to test their service in complete isolation with realistic data, catching integration bugs early without needing all dependencies running.

Rapid Prototyping and Development

When building a new feature or service, developers can use Keploy from day one. As they manually test their API endpoints via a browser or curl, Keploy records those sessions. It instantly generates the corresponding test cases, allowing the developer to build a robust regression suite in parallel with writing the actual feature code, ensuring quality keeps pace with velocity.

Maintaining Test Quality During Refactoring

When refactoring code for performance or clarity, a major concern is accidentally breaking existing functionality. With Keploy, the test suite is derived from real user behavior. This means you can refactor with confidence, knowing that the tests will accurately validate that the core user-facing workflows still perform exactly as they did before the changes.

Model Selection for Development

Developers can utilize OpenMark AI to make informed choices about which AI model to integrate into their applications. By comparing the performance of multiple models on specific tasks, teams can select the one that aligns best with their project goals and user needs.

Cost-Benefit Analysis

Product teams can conduct thorough cost-benefit analyses to determine which model offers the best value for their investment. By examining real costs alongside performance metrics, teams can make strategic decisions that enhance their budget management and overall ROI.

Quality Assurance in AI Features

Quality assurance teams can leverage OpenMark AI to validate the outputs of AI features before they go live. By running tests and analyzing consistency, they can ensure that the model delivers expected results, reducing the risk of errors in production.

Academic Research and Experimentation

Researchers can use OpenMark AI to benchmark various models for academic purposes. By testing different LLMs on a range of tasks, researchers can contribute valuable insights into model performance and characteristics, aiding the broader AI community in understanding model capabilities.

Keploy is an AI-powered testing platform that fundamentally changes how developers ensure software quality. It's designed for modern engineering teams, especially those working with microservices and complex distributed systems, who are frustrated by the slow, manual, and often brittle process of writing and maintaining tests. Keploy's core magic lies in its ability to automatically generate accurate, reliable test cases and mocks by recording real user traffic and application behavior. Using eBPF technology, it observes API calls in real-time, capturing both the request and the response, along with all network interactions with dependencies like databases, internal services, or third-party APIs. This recorded data is then transformed into executable unit, integration, and API tests, complete with stubs for all external dependencies. The result is a dramatic acceleration in achieving comprehensive test coverage—up to 90% in minutes instead of weeks. It supports popular languages like Go, Java, Node.js, and Python, and integrates seamlessly into your existing development workflow and CI/CD pipelines. With Keploy, developers can shift testing left with confidence, catch regressions early, and significantly boost development velocity without compromising on code reliability.

OpenMark AI is a powerful web application designed specifically for task-level benchmarking of large language models (LLMs). It enables users to describe their testing requirements in plain language, run consistent prompts against a variety of models in a single session, and efficiently compare crucial metrics such as cost per request, latency, scored quality, and stability across multiple runs. This capability allows users to observe variance in outputs, moving beyond mere reliance on single, potentially unrepresentative results. Tailored for developers and product teams, OpenMark AI helps in making informed decisions about which model to validate before launching AI-driven features. With hosted benchmarking that operates using credits, there is no need to configure separate API keys for different models, making the testing process streamlined and user-friendly. By focusing on cost efficiency and consistent output quality, OpenMark AI is an essential tool for those who prioritize both performance and budget in their AI implementations.

How is Keploy different from other AI testing tools?

Unlike tools that are simply wrappers around large language models (LLMs) which can generate hypothetical tests, Keploy is behavior-driven.
