## What it is
Skeema is a Go-based CLI tool for declarative MySQL and MariaDB schema management using pure SQL CREATE statements tracked in version control. It diffs live databases against a schema repo to auto-generate DDL, with linting rules and online schema change integration.

## Use cases
- manage mysql schema changes declaratively in git
- auto-generate alter table ddl from schema diff
- keep dev staging and prod database schemas in sync
- lint database schema design in ci
- run online schema changes with gh-ost or pt-online-schema-change
- review database schema changes via pull requests

## When to choose
- you use MySQL or MariaDB and want schema-as-code with pure SQL files
- you need safe, battle-tested automatic DDL generation and diffing
- your team wants PR-based workflows and CI linting for schema changes
- you need non-disruptive ALTERs via online schema change tools

## When to avoid
- you primarily use PostgreSQL or other non-MySQL databases
- you prefer imperative migration scripts over declarative state
- you need the Premium features like foreign key management without paying
