Review drift before release

Schema Compare

Compare a source-of-truth database with one or many targets, review every object difference, and generate a self-contained deployment script without a PowerShell runtime dependency.

  • Windows GUI and cross-platform CLI
  • One source to many targets
  • Safe and manual scripts separated

What it helps you do

A practical path from signal to action

01

Compare the full schema

Diff schemas, tables, columns, indexes, keys, constraints, triggers, views, procedures, functions, types, sequences, synonyms, and DDL triggers.

02

Review changes visually

Filter the color-coded object tree and inspect source and target definitions side by side before generating scripts.

03

Deploy with guardrails

Generate ordered auto scripts and a separate manual-actions list. Apply only after an explicit confirmation and verify the result.

How it works

Typical workflow

  1. Connect

    Choose the source database and one or more target databases, then test both connections.

  2. Compare and review

    Inspect added, removed, changed, identical, and ignored objects with side-by-side definitions.

  3. Generate or apply

    Save self-contained scripts, review manual actions, and optionally apply safe scripts with post-deployment verification.

Run it yourself
