Visit mockzilla.org ↗What is Mockzilla?
Mockzilla is an open-source platform that converts OpenAPI specifications or plain JSON files into hosted mock servers with a single shareable URL. It supports per-pull-request environments, request history and replay, latency/error simulation, and API proxying. The service includes specialized backends for payments (with authorization and decline codes), identity verification (KYC/KYB), and other provider APIs.
Designed for frontend teams, QA, and integration testing, Mockzilla offers a free tier with no card required and enterprise options. The maker has built an MCP server integration allowing Claude Code and other AI agents to inspect specs and spin up mock servers directly from their editor.
