Why KS DB Merge Tools

KS DB Merge Tools are designed for developers who need a practical solution for database comparison and controlled synchronization.

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overly complex and expensive, requiring you to pay for features you don’t use — or lightweight and free, but can be no longer maintained.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.

Our tools are not a "magic sync button" or a replication engine. Instead, they help you:

  • 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 synchronizations in production.

Free versions are fully functional for basic tasks and suitable for commercial use.
