MockAPI Dog provides free, no-signup mock REST APIs and LLM streaming endpoints for testing and developing AI integrations and applications.
MockAPI Dog is a lightweight service for creating free mock REST APIs and LLM streaming endpoints, designed to help developers test integrations quickly and safely. It removes the need for backend setup or credentials when prototyping AI-powered applications, allowing you to simulate responses and behavior before connecting to real services. With no signup required, teams can start mocking endpoints immediately and keep experimentation costs at zero during early development stages.
The platform supports both traditional REST APIs and streaming endpoints compatible with large language model (LLM) workflows, making it suitable for testing chat, completion, and tool-calling flows. Developers can define custom routes, HTTP methods, and responses, including status codes and payloads, to mirror real-world API contracts. Streaming support enables realistic testing of token-by-token or chunked responses, closely matching how production LLM providers behave. MockAPI Dog emphasizes simplicity and speed, so endpoints can be created, adjusted, and discarded as requirements change, without managing infrastructure.
