HyperTest vs Keploy

HyperTest describes itself as an AI test engineer for modern backends. Its SDK records requests, responses, database calls, API interactions, execution order, timing, and data flows from actual traffic. When a pull request opens, the service replays baseline traces against feature-branch code, mocks outbound calls, and isolates execution. HyperTest says it reports 5–10 high-signal findings per pull request with traces and reproduction steps. Listed integration-testing uses include APIs, databases, message queues, microservices, and third-party services. It also lists database testing, contract testing, service virtualization, and test data management. Setup connects a GitHub or GitLab repository, adds OpenTelemetry instrumentation, and runs baseline traces once. Supported languages are Node.js and Java. Starter and Enterprise are self-hosted on Linux. Starter is listed at free, with up to 50 services, unlimited test runs, and a 14-day free trial. Enterprise has unlimited services and runs, with price not listed. There is no free plan beyond the listed trial arrangement, and pricing is otherwise on request.

Keploy turns real application traffic into API tests and dependency sandboxes for local work, continuous integration, and Kubernetes verification. It captures incoming requests and outgoing dependency calls with eBPF and network interception, without application code changes, then replays recordings as regression tests with mocks and isolation. Playground can generate API tests from OpenAPI or Postman inputs, while AI expands edge cases. Listed support covers HTTP(S), HTTP/2, gRPC, Protobuf, GraphQL, Kafka, MySQL, MongoDB, Redis, DynamoDB, Postgres, and RDS. GitHub, GitLab, Jenkins, and Argo are listed CI/CD integrations. A Chrome extension captures XHR and fetch traffic, including headers, cookies, and authentication context, exporting cURL, JSON, or Keploy YAML. The core local record-and-replay platform is open source under Apache 2.0. Plans include free Open Source and Playground tiers, Pro at $19 a month, and Enterprise with discussion-based pricing.
