As answered by people managing ApexSQL Diff and SchemaSmith.
SchemaSmith's answer:
SchemaSmith comes from a team that spent decades wrangling database deployments across SQL Server, PostgreSQL, and MySQL — on-premises and SaaS, single servers and fleets hosting thousands of databases. Every brittle migration script, every drifted environment, every "is the index there or not?" production incident shaped what SchemaSmith is. They built the state-based toolset they wished they'd had: define the schema as metadata, deploy it reliably, and correct drift.
SchemaSmith's answer:
SchemaSmith is state-based: you declare the database's desired end state as metadata and SchemaSmith makes any target match it — no migration scripts to write, number, or order. The same toolset covers SQL Server, PostgreSQL, and MySQL and spans the full cycle: extracting an existing database into versionable packages (SchemaTongs), deploying them (SchemaQuench), and handling reference data (DataTongs).
SchemaSmith's answer:
If you'd rather declare your target schema than hand-author and sequence migration scripts, SchemaSmith's state-based model removes that work and the ordering errors that come with it. It's one toolset across SQL Server, PostgreSQL, and MySQL — not three separate tools — and it's free for any use under a source-available license, with no organization-size or environment caps. It ships as self-contained, single-file command-line executables (Windows, macOS, Linux) with no runtime to install, so it drops into any CI/CD pipeline.
SchemaSmith's answer:
Database developers, DBAs, and DevOps/platform engineers who manage SQL Server, PostgreSQL, or MySQL schemas as code and want repeatable, reviewable deployments across environments — from a single database to fleets of thousands.
SchemaSmith's answer:
Built in C# on .NET 10 and distributed as self-contained, single-file executables (no runtime install). Schema extraction is pure SQL with no external database SDK dependencies.
