Custom Responses. Clean Request Logs. Instant Feedback.
Create controlled endpoints for API simulation, webhook testing, and comprehensive debugging
Revilo Echo gives you endpoints you control — perfect for simulating API behaviour, testing error flows, and capturing every detail of incoming requests. Use it to test webhooks, stub responses, or observe how your application handles edge cases like 404s and 503s.
Built for developers who need reliable, inspectable endpoints that provide instant feedback and complete visibility into request patterns.
Create custom endpoints in seconds with full control over response codes, headers, and body content.
Capture and inspect every request detail including headers, payloads, query parameters, and metadata.
Access a comprehensive dashboard showing all incoming requests with full replay and inspection capabilities.
Powered by CoreAuth authentication, ensuring your development environment remains secure and isolated.
Simulate any HTTP status code (200, 404, 500, etc.) with custom response bodies, headers, and delays to test how your application handles different scenarios.
Log headers, payloads, query parameters, and metadata for every request. Never miss a detail when debugging API interactions.
Instantly replay or inspect request history in the dashboard. Perfect for debugging and understanding request patterns.
Test webhook integrations by creating endpoints that capture and log incoming webhook payloads from external services.
Test your frontend against realistic API responses, debug integration issues, and ensure your UI handles all possible scenarios gracefully.
Create comprehensive test scenarios for API integrations, test error handling, and validate response processing logic.
Debug third-party API integrations, test webhook handling, and ensure your application works correctly with external services.
Test how your application handles edge cases like 404s, 503s, and other error conditions to ensure robust error handling.
Define your custom endpoint with desired HTTP method, path, and response configuration including status codes and body content.
Point your application to the Revilo Echo endpoint and send requests as you would to any real API service.
View real-time request logs in the dashboard, inspect payloads, and replay requests for detailed analysis.
Adjust response configurations, test different scenarios, and refine your API integration based on insights gained.
Test mobile app API integrations by creating mock endpoints that simulate your backend services during development.
Validate web application API calls by creating controlled endpoints that return predictable responses for consistent testing.
Test microservice communication by creating mock endpoints that simulate service responses and capture inter-service requests.
Test cloud service integrations by creating endpoints that simulate AWS, Azure, or other cloud provider API responses.
