Antara DB Diff compares procedures, views, tables, triggers and user-defined types between any two SQL Server instances, then shows the exact side-by-side SQL difference for every object that moved.

What it compares

Five object types. One consistent picture.

Toggle any category on or off before you analyze — Antara only scripts and compares what you ask it to.

Procedures & Functions

Stored procedures and scalar/table functions, normalized before comparison.

Views

View definitions compared for structural and logical changes.

Tables

Columns, defaults, constraints and keys, diffed field by field.

Triggers

Trigger bodies across both servers, matched to their parent tables.

User Defined Types

Alias types and table types, including their column definitions.

Object status

Every object lands in one bucket

No ambiguity about what needs your attention before a release.

Modified

Definition differs between source and destination

MissingInLeft

Exists on destination only

MissingInRight

Exists on source only

Match

Identical on both servers

Workflow

Five steps from two servers to a clear answer.

  1. 01

    Enter both servers

    Point Antara at a Source Server and a Destination Server — dev, staging, prod, wherever you need a diff.

  2. 02

    Select the database

    Pick the target database from a picker loaded live from the source server.

  3. 03

    Choose what to compare

    Enable or disable procedures, views, tables, triggers and UDTs independently.

  4. 04

    Click Analyze This

    Antara scripts every enabled object on both servers and classifies each one.

  5. 05

    Inspect the SQL

    Select any object in the tree to see its side-by-side difference, line by line.

The diff viewer

Every change, in the exact place it happened.

The object tree on the left, the SQL side by side on the right — nothing to reconstruct from a log file.

Local & persistent

Settings stay where you left them

Servers, database, compare toggles and theme are saved locally under %AppData%/AntaraDbDiff, so the next comparison starts exactly where the last one ended.

Known limitations

What we're still expanding

  • UDT table-type scripting currently focuses on columns; advanced constraints and index definitions are on the roadmap.
  • Comparison quality depends on generated script fidelity for each object provider.
