Beeceptor

Overview

Beeceptor is an API mock server that enables developers to create dummy REST, SOAP, GraphQL, and gRPC APIs without coding via an online interface. It intercepts HTTP requests, allows configuration of mock responses, inspection of traffic, and simulation of real-world conditions like latency and rate limits. Targeted at developers for prototyping, testing, debugging, and demos, it stands out with features like local tunneling to expose localhost services, stateful mocks, dynamic templated responses, and AI-powered mock generation from prompts or specs.¹²³⁹

Key Features

• Mock API Endpoints - Create hosted dummy REST, SOAP, GraphQL, and gRPC APIs without coding.
• Request Inspection - Intercept and review HTTP requests including headers, payloads, and query parameters in the dashboard.
• Custom Mock Rules - Define responses with status codes, headers, body, latency, and rate limits.
• Local Tunnel - Expose local services to the internet for sharing applications and demos from localhost.
• Dynamic Responses - Generate contextual responses based on request parameters using templates.
• Stateful Mocks - Maintain context across API calls with lists and key-value storage.
• Proxy Layer - Wrap third-party APIs to inspect traffic, record interactions, and override responses.
• AI-Powered Mocks - Generate realistic responses from prompts, real traffic, or uploaded OpenAPI/Swagger specs.
