In their own words
Skeema
Skeema is a declarative, SQL-based schema management utility for applying repository changes to MySQL and MariaDB tables and routines. It generates SQL DDL from schema files and provides diff, lint, push, and pull commands. Configurable linter rules identify unsafe changes, and Skeema verifies generated ALTER TABLE statements in a workspace before proceeding. For online schema changes, it supports database-native alterations and external tools including pt-online-schema-change and gh-ost, with execution configurable by environment and table size. Schema directories can map to multiple servers or schemas, and the utility can detect drift across shards. Listed compatibility includes MySQL 5.5–9.7, MariaDB 10.1–12.3, and Percona Server; AWS Aurora MySQL 5.7–8.4 is listed for Premium. Skeema Cloud Linter can provide automatic diff and lint output for related GitHub commits. All editions can use SSL/TLS, while Premium adds client certificates, CA verification options, and SSH tunnels. The Community plan is free at free. Plus costs $124 a month and Max costs $499 a month.
SQL Delta
SQL Delta is a Windows tool for comparing database schemas and data before changes reach production. SQL Delta 7 compares source and target databases that use the same server type; SQL DXP is intended for comparisons across different server types. Schema Compare shows structural differences in live databases or snapshots and lets users select what to include in a deployment script. Data Compare identifies row-level differences between environments. Users can review and edit synchronization scripts before executing them against a target, and projects can add custom script to deployment scripts. SQL Delta can save HTML reports and XML snapshots for release reviews or recovery work. Project completion events and command-line execution support automated runs. Editions are listed for SQL Server, MySQL, Oracle, and PostgreSQL. A separate Read Only Edition allows comparison and script generation but prevents direct script execution. The latest full product download has a 14-day trial. The MySQL single-license plan is $185 as a one-time purchase and includes a two-year software update subscription; purchase terms also describe a perpetual license.
