Mockzilla

A powerful self-hosted API mocking platform for development and testing. Deploy your own private mock server with an intuitive interface and advanced response generation capabilities.

Quick Start

In-Memory with PGLite (Recommended for Development)

Start instantly with ephemeral storage:

docker run -p 36666:36666 andrecrjr/mockzilla:latest

To persist data between container restarts:

docker run -p 36666:36666 -v mockzilla-data:/data andrecrjr/mockzilla:latest

Persistent with External PostgreSQL (Recommended for Production)

Run with an external database:

docker run -p 36666:36666 -e DATABASE_URL=postgresql://username:password@host:5432/database_name andrecrjr/mockzilla:latest

The mock server and dashboard will be available at http://localhost:36666

Configuration

The following environment variables can be configured:

• DATABASE_URL (optional): PostgreSQL connection string (when using an external database)
• PORT (optional): Port to run the server on (default: 36666)
