Welcome to SureStage
SureStage is a sandboxed API mocking, testing, and simulation platform that enables teams to create realistic mock API environments for development, testing, and demonstration purposes.
What You Can Do
- Create mock API simulations - Spin up isolated sandbox environments with custom routes, responses, and stateful behavior
- Import existing APIs - Import OpenAPI/Swagger specs, Postman collections, and other formats to auto-generate mock endpoints
- Record and replay - Proxy traffic to real APIs, record request/response pairs, and replay them in isolated environments
- Automate with flows - Build multi-step test flows that chain API calls with conditional logic
- AI-powered mocking - Generate realistic mock responses using AI based on your API schema
- Multi-protocol support - Mock REST, GraphQL, SOAP, gRPC, and database protocols
