MMDB CLI 🛠️

MMDB CLI is our first publicly available open-source project, developed to simplify working with MMDB files. It is a command-line tool that allows you to generate, modify, export, and inspect MMDB files, among other functionalities.

What is MMDB?

The MMDB (MaxMind Database) is a widely used database file format designed to map IPv4 and IPv6 addresses to specific data records through an efficient binary search tree structure. For more details, please refer to the MMDB File Format Specification.

Why MMDB CLI?

We’ve always wanted a comprehensive and easy-to-use tool for working with MMDB files. That’s why we developed MMDB CLI, to make handling MMDB files simple and efficient, without the need for coding.

With MMDB CLI, you can:

• Generate MMDB files from JSON datasets
• Modify existing MMDB files (Insert, Update, Delete)
• Dump MMDB files into JSON format
• Inspect the contents of MMDB files
• And much more…
