## What it is
py-kms is a Python-based KMS (Key Management Service) server emulator that responds to v4, v5, and v6 KMS requests to activate volume-licensed Windows and Microsoft Office products. It can run as a standalone server, via Docker, systemd, or with a built-in GUI, and stores persistent data in SQLite.

## Use cases
- activate windows and office volume license editions on my lan
- self-host a kms server in docker
- emulate a kms activation server for testing
- activate windows 10 and office 2019 with gvlk keys
- run a lightweight kms emulator written in python

## When to choose
- you need to activate volume-licensed Windows or Office clients on an isolated network without a real KMS host
- you want a lightweight, cross-platform KMS emulator deployable via Docker or systemd
- you prefer a Python implementation with an optional GUI and SQLite persistence

## When to avoid
- you need to activate retail or OEM-licensed products, which KMS does not cover
- you require a legally licensed Microsoft volume-activation infrastructure with official support
- you need active development or recent feature updates, as the project is in maintenance

## Facets
- artifact type: service
- maturity: maintenance
- function: networking, security, cli, gui, self-hosted
- domain: security, windows, developer-tools, self-hosted
