What DBC is

DBC is a free, MIT-licensed Go command-line tool for taking database schema snapshots and comparing them across versions, environments, or database systems. It supports MySQL, PostgreSQL, SQL Server, Oracle, and SQLite. The comparison tracks tables, columns, indexes, foreign keys, and constraints; optional checksums can flag data modifications, and exact row counts are enabled by default. Results are available in text, JSON, and HTML formats. Database drivers run as separate executables and communicate with the core application over JSON-RPC using standard input and output; the project notes that these processes have timeouts. Installation instructions describe building the core and drivers from source with Make commands. The project lists CI/CD examples, Docker support, migration script generation, and a web UI as roadmap items rather than current features. The GitHub Releases page opened for this research showed no release entries. DBC is listed for Linux, macOS, and Windows.

Who it suits

DBC suits developers or database teams who want to compare schemas across supported database systems from a command line. It is a fit for users comfortable building software and drivers from source.

What it does well

  • Supports five listed database systems.
  • Can export comparison results as text, JSON, or HTML.
  • Exact row counts are enabled by default.
  • Licensed under MIT.

What to know first

  • Installation involves building from source.
  • No GitHub release entries were shown.
  • Migration script generation is a roadmap item.

Limits

DBC does not currently provide migration script generation; that capability is on the roadmap. The web UI, Docker support, and CI/CD examples are also roadmap items.

Getting started

  1. Open the DBC project page on GitHub.
  2. Follow the README instructions to build the core application with Make.
  3. Build the database drivers with Make.
  4. Use the installation instructions for Linux, macOS, or Windows.
  5. Capture schema snapshots and compare them across versions, environments, or database systems.

Verdict

DBC provides cross-engine schema comparisons and optional data checksums in a free command-line tool. Building from source is part of its documented installation, while several requested capabilities remain on the roadmap.
