SchemaSmith vs SQL Toolbelt

Free, unified deployment-focused CLI for SQL Server, PostgreSQL, and MySQL — vs Redgate’s 10-tool, per-user, Windows-centric bundle.

Chaos vs Precision: Product Comparisons

Quick Summary

SQL Toolbelt Essentials is Redgate’s 10-tool bundle for SQL Server developers, sold per user. SchemaSmith is a free, source-available CLI focused on the deployment-critical surface: schema deploy, reference-data deploy, source-control-native definitions, multi-server orchestration, and dependency-aware ordering, all unified in one tool covering SQL Server, PostgreSQL, and MySQL. SchemaSmith does not replace every Toolbelt function — SQL Prompt, SQL Search, SQL Doc, and SQL Test are SSMS-IDE / documentation / testing tools out of SchemaSmith’s scope — but it covers the deployment pipeline end-to-end without per-user licensing.

Technical Comparison

How the two approaches differ in scope, tooling, and developer experience.

Aspect SchemaSmith SQL Toolbelt Essentials
Scope Deployment-focused: schema deploy, reference-data deploy, multi-server orchestration, drift detection 10-tool bundle covering schema/data deploy plus SSMS IDE features, search, documentation, and testing
Approach Declarative state-based, CLI-first Mix of state-based diff tools and SSMS plug-ins; GUI-first
Schema Deployment SchemaTongs (extract) + SchemaQuench (apply) SQL Compare
Reference Data Deployment DataTongs + declarative DataDelivery blocks; two-pass FK-aware loader SQL Data Compare (separately licensed inside the bundle)
Platform Coverage SQL Server, PostgreSQL, MySQL (platform-specific schema definitions) SQL Server & Azure SQL only
Deployment Surface Native CLI runs on Windows, macOS, Linux, ARM64 Windows GUI / SSMS plug-ins; SQL Compare CLI on Linux/macOS via Docker
Source Format JSON template files in source control; per-object diffs Source SQL files alongside Redgate’s project format
CI/CD Integration Native CLI is the CI/CD step; idempotent SQL Compare CLI available; deeper automation features bundled in higher Redgate tiers
Drift Detection Built-in — runs on every deployment On-demand comparison via SQL Compare
Failed Deployment Recovery Checkpoint & resume (--ResumeQuench); skips completed work on retry Re-run; partial-state cleanup is the deployer’s responsibility
SQL Server Availability Groups Target:SecondaryServers — primary plus secondaries quenched in parallel Apply per server; orchestration is the deployer’s problem
SSMS IDE Integration Not in scope — SchemaSmith is a deployment CLI, not an IDE plug-in SQL Prompt (IntelliSense), SQL Search, SQL Source Control all integrate into SSMS
Licensing Free under SSCL v2.0 (source-available); unlimited seats Commercial bundle, per-user; 14-day trial

Where SchemaSmith fits in the Toolbelt-tool map

SchemaSmith does not replace every Toolbelt tool. It replaces the deployment-pipeline ones — the parts of the bundle that get scripted into CI/CD — and leaves the SSMS IDE and documentation/testing tools out of scope.

SQL Toolbelt Tool Purpose SchemaSmith
SQL Compare Schema comparison & deployment SchemaTongs + SchemaQuench
SQL Data Compare Data comparison & deployment DataTongs + DataDelivery
SQL Source Control SSMS source-control integration JSON template files in source control
SQL Multi Script Run scripts across multiple servers SchemaQuench multi-target deployment + AG secondaries
SQL Dependency Tracker Object dependency visualization SchemaQuench automates dependency ordering and produces deterministic deploy plans
SQL Data Generator Synthetic test-data generation Partial — DataTongs extracts existing reference data; SchemaSmith does not generate synthetic test data
SQL Prompt SSMS IntelliSense / refactoring Not in scope — SchemaSmith is a deployment CLI, not an SSMS plug-in
SQL Search Search across database objects in SSMS Not in scope — SchemaSmith is a deployment CLI, not an SSMS-integrated search panel
SQL Doc HTML / PDF schema documentation Not in scope
SQL Test Unit-testing framework (tSQLt wrapper) Not in scope — use tSQLt directly (the framework SQL Test wraps)

If your team’s use of SQL Toolbelt is mostly SQL Compare + SQL Data Compare + SQL Multi Script + SQL Dependency Tracker (the deployment surface), SchemaSmith covers that path end-to-end. If you rely heavily on SQL Prompt, SQL Search, SQL Doc, or SQL Test, SchemaSmith does not replace those — pair it with the standalone tool you already use, or keep the bundle for those four developers who actually use them.

Choose SchemaSmith when...

  • The deployment pipeline (schema, data, multi-server, dependency ordering) is the part of the bundle your team actually uses in CI/CD
  • You manage SQL Server, PostgreSQL, and MySQL — or expect to expand beyond SQL Server
  • You want native cross-platform CLI without SSMS or Windows dependency
  • You prefer source-control-native JSON template files over Redgate’s proprietary project format
  • You need built-in drift detection, idempotent CI/CD, checkpoint-and-resume, and AG secondary support
  • You want a license that does not change as the team or footprint grows — free, source-available, no per-seat fees

Choose SQL Toolbelt when...

  • Your team is SQL Server only and lives inside SSMS for daily database work
  • You depend on SQL Prompt for IntelliSense / refactoring as a daily-use developer tool
  • You need SQL Doc for generated schema documentation or SQL Test for tSQLt-wrapped unit tests
  • You have established Redgate workflows and team expertise you want to keep
  • You prefer Redgate’s GUI-based comparison and SSMS-integrated search experience

Pricing & Licensing

How the two tools differ on cost, license terms, and what changes as the team grows.

Aspect SchemaSmith SQL Toolbelt Essentials
License SSCL v2.0 (source-available) Commercial bundle, proprietary
Cost $0/year — free for any purpose, any organization, any scale Per-user; check vendor for current bundle pricing
Seat Model Unlimited users, no per-seat charge Pricing scales with developer seat count
Scope Deployment-pipeline tooling: SchemaTongs, SchemaQuench, DataTongs 10-tool bundle including SSMS plug-ins (SQL Prompt, SQL Search), SQL Doc, SQL Test, and the deployment surface
CI/CD Automation Included in the free CLI SQL Compare CLI available; deeper automation features bundled in higher Redgate tiers
Cost as You Scale Stays at $0/year regardless of team size Per-user license count grows with the team

Bundle vs. focused pipeline

Bundles are appealing when several tools in the bundle are daily-use for the whole team. They get expensive when you’re paying per user for tools only a few people actually open. SchemaSmith covers the pipeline tools (deploy, data, multi-server, dependency ordering) at no per-user cost — pair it with the IDE / documentation / testing tools you actually use, instead of paying for the whole bundle to get the deployment surface.

Adopting SchemaSmith Alongside SQL Toolbelt

Adopting SchemaSmith on top of an existing SQL Toolbelt workflow is usually additive. SchemaSmith owns the deployment pipeline; the SSMS-integrated tools (SQL Prompt, SQL Search) and the documentation / testing tools (SQL Doc, SQL Test) keep doing their job.

  1. Extract current state with SchemaTongs. Point it at a representative database and let it capture every table, view, procedure, and function as JSON template files.
  2. Review the generated metadata. The JSON files become the source of truth for the deployment pipeline — commit them to source control alongside the rest of your repo.
  3. Deploy with SchemaQuench. Future schema changes are edits to the JSON; SchemaQuench generates and applies the DDL on every run, idempotently. Drop SQL Compare / SQL Data Compare / SQL Multi Script from the deployment scripts — SchemaSmith covers the same surface end-to-end.
  4. Right-size the bundle. If only a few developers use SQL Prompt, SQL Doc, or SQL Test daily, those people can keep individual licenses for those tools while everyone else moves to the free SchemaSmith CLI for deployments.
