MockBase
Instant hosted mock API server with conditional responses and live request inspector
Overview
MockBase is a hosted mock API server for frontend teams, QA, and developers who need reachable endpoints before a backend exists. It supports REST, GraphQL, and SOAP and can be used anonymously or with an account for expanded limits.
Routes can match on query params, headers, JSON body paths, GraphQL operation names, or SOAP elements and render responses with sandboxed Jinja2 templates. Features include stateful CRUD with Redis-backed storage, conditional and weighted responses, chaos injection and deterministic rate limit simulation, callouts, delays, and the ability to import or export OpenAPI and record and replay real APIs.
Every request is streamed to a live inspector showing method, path, headers, bodies, latency and client IP, and recent requests are retained. The result is faster integration debugging and more realistic frontend testing by exercising success and failure paths without a production backend.
MockBase in a Nutshell
Who is it for?
Frontend teams, QA engineers, and developers who need reachable API endpoints before a real backend exists.
Problem
Front-end and QA teams struggle when backend APIs aren’t ready, causing integration delays and uncertain tests. They need realistic, controllable endpoints to validate flows, error paths, and performance without a live backend.
Solution
MockBase provides a hosted mock API server supporting REST, GraphQL, and SOAP, with conditional routing, live request inspection, and sandboxed templates. It lets teams simulate real-world responses, delays, and rate limits to accelerate testing and debugging.
What makes it unique
It combines a hosted, easy-to-use mock server with stateful Redis-backed storage, deterministic and chaotic response capabilities, and a live streaming inspector for every request. It also supports import/export of OpenAPI definitions and record/replay of real APIs, plus granular matching on query params, headers, bodies, and GraphQL/SOAP specifics.
Use Cases
Create mock REST endpoints
Create mock GraphQL schema
Simulate conditional responses
Stream live request inspector
Import OpenAPI specs
Record and replay real APIs
