Compare and Sync Database Schema and Data

KS DB Merge Tools is a lightweight, affordable, and developer-focused solution for database diff and merge:

Why KS DB Merge Tools

KS DB Merge Tools are designed for developers who need a practical solution for database comparison and controlled synchronization. Our tools are not a "magic sync button" or a replication engine. Instead, they help you to:

• Analyze differences visually or using command line
• Generate or apply synchronization scripts (where supported)
• Integrate these results into your development and release process

The goal is clarity and control: understand what has changed, produce synchronization script, review, test, and deploy it as part of your release. Not to automate ongoing synchronizations in production.

Many other tools are either overly complex and expensive, requiring you to pay for features you don’t use; or lightweight and free, but can be no longer maintained. We aim for the middle ground: a focused, actively developed solution at a reasonable cost. And our free versions are fully functional for basic tasks and suitable for commercial use.
