It records API calls, database queries, and streaming events, then replays them as tests without requiring code changes or SDKs. It uses eBPF at the network layer, making it language-agnostic across Go, Java, Node.js, Python, Rust and more. It also virtualizes infrastructure like Postgres, MySQL, MongoDB, Kafka and RabbitMQ, and uses AI with OpenAPI schemas to expand test coverage by finding boundary values and edge cases. Setup is a single install script followed by `keploy record` and `keploy test` commands. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How does Keploy generate API tests without modifying application code? Keploy uses eBPF to capture network traffic at the kernel level, recording real API calls, database queries, and streaming events, then replays them as tests and mocks. Because interception happens at the network layer rather than through SDKs, it works across languages like Go, Java, Python, Node.js, Rust, and more without requiring code changes. _daily.dev surfaces tools like this for teams weighing code-less approaches to API test generation._ ### Can Keploy mock non-HTTP dependencies like databases and message queues for testing? Yes, Keploy virtualizes infrastructure beyond HTTP endpoints, recording and replaying Postgres, MySQL, MongoDB, Kafka, and RabbitMQ interactions deterministically. This lets tests run without re-provisioning real infrastructure, since recorded database queries and streaming events are captured and replayed alongside API calls. _Developers picking test infra mocking strategies track options like this through daily.dev._ ## Community discussion Top comments from developers on daily.dev. **@pdfopsdev** · 4 upvotes > recording at the network layer is great until your payloads have timestamps or UUIDs in them, then replay fails on literal diff even though the behavior's identical. curious if keploy has field masking built in or you have to hand-write matchers for that. **@nark3d** · 2 upvotes > Recording at the network layer is clever, because it means the same generated tests cover a Postgres call and a Kafka publish without anyone writing a wrapper for either. Freezing time alongside the mocks is a detail I'd have expected to be missing. What's it like to debug when a replay diverges from the recording, does it tell you which dependency drifted or just that the output differs? ## Similar posts on daily.dev - [What Dependency Mocking Software Needs to Handle in a Cloud Native Architecture](https://daily.dev/posts/what-dependency-mocking-software-needs-to-handle-in-a-cloud-native-architecture-ydprmf6w5) · Cloud Native Now · 0 upvotes · 0 comments - [How Open-Source Automation Tools Handle the Testing Problem That Cloud-Native Independent Deployment Creates](https://daily.dev/posts/how-open-source-automation-tools-handle-the-testing-problem-that-cloud-native-independent-deployment-ejpubd1uw) · Container Journal · 0 upvotes · 0 comments - [How Independent Service Deployments Expose the Limits of Conventional Regression Testing Tools](https://daily.dev/posts/how-independent-service-deployments-expose-the-limits-of-conventional-regression-testing-tools-bxfiuoiww) · DevOps.com · 0 upvotes · 0 comments - [10 Best Microservices Testing Tools for Kubernetes in 2026](https://daily.dev/posts/10-best-microservices-testing-tools-for-kubernetes-in-2026-42bsdwcbx) · MetalBear · 2 upvotes · 0 comments - [The Regression Testing Habit That Changed How I Think About Shipping Code](https://daily.dev/posts/the-regression-testing-habit-that-changed-how-i-think-about-shipping-code-2dtsz5lot) · Code Like A Girl · 1 upvotes · 0 comments --- Tags: [#testing](https://daily.dev/tags/testing), [#golang](https://daily.dev/tags/golang), [#agentic-ai](https://daily.dev/tags/agentic-ai) [View this post on daily.dev](https://daily.dev/posts/github---keploy-keploy-open-source-platform-for-creating-safe-isolated-production-sandboxes-for-ap-xca7wgl76) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"GitHub - keploy/keploy: Open-source platform for creating safe, isolated production sandboxes for API, integration, and E2E testing.","url":"https://daily.dev/posts/github---keploy-keploy-open-source-platform-for-creating-safe-isolated-production-sandboxes-for-ap-xca7wgl76","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/github---keploy-keploy-open-source-platform-for-creating-safe-isolated-production-sandboxes-for-ap-xca7wgl76"},"datePublished":"2026-10-15T19:30:37.700Z","dateModified":"2026-10-15T19:46:54.477Z","description":"Keploy is an open-source API and integration testing tool that auto-generates tests and mocks from real traffic.
