Modern architectures are only as fast as their slowest dependency. Tenjin TruSim breaks the "waiting game" by virtualizing unavailable third-party APIs, legacy mainframes, RPC frameworks and incomplete microservices. It creates a stable, high-fidelity simulation of your entire ecosystem, allowing development and testing to proceed in parallel without infrastructure bottlenecks.
Book a Demo
Start testing weeks earlier by mocking services that are still under development.
Eliminate transaction fees and "pay-per-hit" costs from third-party provider sandboxes.
Remove the flakiness of shared test environments by using dedicated virtual responders.
Mock complex backend systems including REST, SOAP, GraphQL, GRPC and Modern AI Protocols. TruSim provides a "complete" environment even when external providers are offline or internal core systems are inaccessible.
Do not spend hours coding stubs. Tenjin’s AI converts Swagger/OpenAPI docs or recorded live traffic into intelligent virtual services that mirror real-world system behavior.
Move beyond static responses. TruSim supports stateful transactional logic and data-driven virtualization, ensuring the mock service responds correctly to complex, multi-step business flows.
A single engine for the entire enterprise stack, governing REST, SOAP, GraphQL, GRPC and Modern AI Protocols ensuring seamless simulation from legacy cores to modern cloud APIs.
