In their own words
drawDB
drawDB is a browser-based database diagram editor for modeling schemas, importing existing definitions and exporting SQL. It supports Generic, MySQL, PostgreSQL, SQLite, MariaDB, Microsoft SQL Server and Oracle diagrams. Imports include drawDB JSON and DDB files, DBML, and SQL scripts for the listed database systems; exports include SQL, image and document formats, drawDB JSON, DBML, Mermaid and Markdown. The free plan is listed at free and includes local diagrams, SQL dialects, and import and export. In the open-source editor, diagrams and custom templates live in browser IndexedDB, tying them to that browser profile. The maker says it can also be self-hosted with Docker. Pro options add cloud storage and sync, public sharing, AI assistance and version history; team options include workspaces, roles, diagram permissions and live collaboration. The AI assistant can create or edit schema elements from prompts, while the MCP server provides read-only access for compatible coding tools to schemas in Pro cloud workspaces. Schema context is sent to the AI service when it operates on a diagram.
Schemity
Schemity is database design software that connects to live databases and previews proposed schema changes before they are applied. It lists PostgreSQL, Supabase, MySQL, MariaDB, SQL Server, and SQLite support. A migration displays its proposed changes and effects, and runs only when the user clicks Migrate. Design tools include ERD creation, inferred relationships, SQL and DBML import, check constraints, junction table generation, and schema linting across 26 problem classes. Its local MCP server offers 16 tools for Claude Code, Claude Desktop, Cursor, Codex, OpenCode, and other MCP hosts. The desktop app stores work in plain JSON files that can be version-controlled with Git. It has no cloud backend, accounts, analytics, or telemetry, but transmits an automatically generated machine ID and country code for license verification. A two-week desktop trial unlocks every feature without a credit card. After it ends, offline design remains available, while live database features and Context Views pause until a license is active. Lite is free; the License is $129 one-time.
