drawDB is a free, open-source database diagram editor that turns entity-relationship designs into SQL. It suits developers and small teams designing relational schemas for review or implementation, especially anyone who wants a quick visual canvas without signing up for a database tool account. Diagrams live in the browser with local persistence, and the same editor self-hosts with Docker for teams that want it on their own infrastructure.[1]
Quick verdict
Developers and small teams designing relational schemas benefit most from drawDB. Its free local-first canvas with six-dialect SQL export turns ER designs into working DDL with no account required. The material constraint is scope: it designs schemas rather than operating databases, and SSO plus data-residency documentation are absent. If you want fast visual schema design with Docker self-hosting, choose the free editor; if the team needs shared workspaces, real-time editing, or AI help, choose a Pro plan instead.[1][2][3]
Key features
Visual ER canvas Design tables, fields, indexes, and relationships on a diagram-first surface with per-field types, constraints, defaults, and comments.[1]
Six-dialect SQL export Generate DDL for MySQL, PostgreSQL, SQLite, MariaDB, SQL Server, and Oracle, plus diagram images and JSON.[1]
SQL and JSON import Paste existing database SQL or JSON to visualize a schema you already run, instead of redrawing it.[1]
Starter templates Begin from built-in templates for apps such as invoicing, blogs, and e-commerce rather than a blank page.[1]
No-account local editing The open-source editor runs entirely in the browser and stores diagrams locally, so nothing leaves your machine unless you share it.[1]
Docker self-hosting Run the same editor on your own infrastructure with Docker or Docker Compose in minutes.[1][2]
Pro cloud workspaces Paid plans add cloud sync, team workspaces, real-time collaboration, roles, and shared team resources.[1]
AI assistance and API keys Pro adds AI-powered design help and API keys with MCP access for programmatic and agent-driven workflows.[1][2]
Who will love it
Developers sketching a new schema: a blank canvas plus templates plus instant DDL is the shortest path from idea to migration file.[1]
Small teams reviewing a design together: share links and published templates make schema review a conversation instead of a SQL dump.[1]
Open-source-first shops: AGPL-3.0 code, localStorage persistence, and Docker self-hosting fit teams that keep tooling in-house and auditable.[1][2]
Who should avoid it
Teams needing a full database IDE will stall: drawDB designs schemas and does not run queries, manage data, or monitor production databases.[1]
Enterprises requiring SSO and data-residency paperwork should verify first: team single sign-on and cloud data residency are not documented on the observed pages.[1]
Non-technical users wanting no-code apps will struggle: the canvas assumes relational concepts like keys, constraints, and dialects.[1]
Alternatives and compatibility
Conditional alternatives: teams wanting a simpler notation may fit dbdiagram better, and general diagramming tools cover drawing without SQL; neither replaces drawDB's DDL generation role.[1]
Existing catalogue neighbours: the catalogue relates drawDB to Azimutt as an alternativeTo entry; both serve visual schema design, with drawDB's free local-first editor as the differentiator.[1]
Migration paths: existing schemas enter through SQL or JSON import, and designs leave as dialect-specific DDL, images, or JSON, so prior work is not locked in.[1][2]
If the job is designing a relational schema and turning it into correct SQL, drawDB is the free starting point; pay for Pro only when the team needs shared workspaces, real-time editing, or AI help. Scope, not quality, is the decision.[1][2]
Questions worth asking
What is the best drawDB alternative for non-technical users?
dbdiagram or a simpler visual notation may feel friendlier, since drawDB assumes relational concepts like keys and constraints. A general canvas tool also works for pure diagramming, but you lose DDL generation.[1]
Is drawDB really no-code?
Drawing the diagram is click-driven, but using the output well assumes SQL literacy: choosing dialects, reviewing generated DDL, and applying migrations are developer tasks. Non-technical teammates can view and comment on shared diagrams without writing code.[1]
How much does drawDB cost per month?
The open-source editor is free with no account required. drawDB Pro (cloud sync, team workspaces, real-time collaboration, AI assistance, API keys) is billed per plan through Paddle; exact tier prices were not confirmed on the observed pages in October 2026, so check the official pricing page before budgeting.[1][2]
