Lucidchart Alternatives for Database Diagrams (2026): 6 Tools Compared

Somebody asks for the current ER diagram, and the one on the Lucidchart canvas is three releases old. The Lucidchart alternative that closes that gap is DbSchema: it reads the schema from the live database over JDBC, keeps the design in a model file you can put in Git, and shows what changed when the database moves on. Miro, Microsoft Visio, Draw.io and ChartDB are compared below on the same question: where does the diagram come from?

The best Lucidchart alternative depends on where the diagram comes from

The answer depends on one question: does the diagram have to come out of the database, or out of a shape library? Lucidchart sits in between. Lucid's database diagram page says its designer "supports DBMS platforms such as MySQL, Oracle, PostgreSQL, and Microsoft SQL Server", and Lucid's help centre describes the import as a round trip you do by hand: choose your DBMS, copy the query Lucidchart gives you, run it against your database, then upload or paste the result. Its Export to SQL works "with the exception of connections between tables". The import is available on every Lucidchart plan, including Free, and the diagram is current until the next migration.

The vendors' pages, read on 3 November 2026, split the six tools into two groups.

Tools that take the schema from a database or a query result

Only DbSchema reads the database itself; the other two wait for a result you paste:

Canvas tools where you draw the tables

None of the three reads a database, so every table on the diagram is placed by hand:

DbSchema reads the diagram from the database and keeps it current

The foreign keys a diagram needs are already in the database. This PostgreSQL 17.6 schema has two tables and one foreign key:

CREATE TABLE customers (id integer PRIMARY KEY, email text NOT NULL);
CREATE TABLE orders (id integer PRIMARY KEY,
                     customer_id integer NOT NULL REFERENCES customers (id),
                     total numeric(10,2));

The catalog lists the relationship without anyone drawing it:

SELECT tc.table_name, kcu.column_name,
       ccu.table_name AS references_table, ccu.column_name AS references_column
FROM information_schema.table_constraints tc
JOIN information_schema.key_column_usage kcu
  ON kcu.constraint_name = tc.constraint_name AND kcu.table_schema = tc.table_schema
JOIN information_schema.constraint_column_usage ccu
  ON ccu.constraint_name = tc.constraint_name AND ccu.table_schema = tc.table_schema
WHERE tc.constraint_type = 'FOREIGN KEY';

DbSchema reads this information through the engine's JDBC driver, which it downloads the first time you connect (connect to a database), and draws the tables with their foreign keys as lines. Connecting and reverse-engineering are in the free Community Edition. Where the data links two tables that have no foreign key, you add a virtual foreign key: it exists only in the DbSchema model and DbSchema never creates it in the database.

The diagram becomes a design you keep once you save it with File → Save Model to File, which needs DbSchema Pro. The model file holds the tables, keys, diagram layout and your comments, and it goes into Git like any other file in the repository. Editing the diagram changes the model only; the database changes when you decide it should.

When somebody runs the next migration, ALTER TABLE orders ADD COLUMN shipped_at timestamptz, the catalog shows the new column at once. In DbSchema Pro, Database → Refresh Model from Database compares the model with the database and lists the difference. In the Synchronize Model and Database dialog you choose, row by row, whether the model or the database wins, then apply the choice to the model, commit it in the database, or generate the SQL script without running it (schema synchronization).

The same model exports HTML5 documentation from File → Export As... → HTML5/PDF Documentation, with the diagram as a vector image, for colleagues who will never open DbSchema. DbSchema Pro costs 294 USD one-time with the first year of updates, or 29.40 USD a month (DbSchema purchase page).

Miro and Lucidchart draw on a canvas and never read a database

Miro is a whiteboard for unstructured team work: workshops, planning and diagrams on an infinite canvas, with Mermaid, UML, AWS and BPMN diagramming listed on its pricing page. That page does not list ER diagrams or a database import. The Free plan keeps 3 boards editable; Starter costs 8 USD and Business 20 USD per member a month, billed yearly, and Starter adds import of Visio and Lucidchart files.

Lucidchart is the more structured of the two canvases, with an Entity Relationship shape library and the query-and-paste import described above. Neither connects to a database by itself, so a table added in a release reaches either canvas only when somebody imports or redraws it.

Microsoft Visio is Microsoft's canvas, with ERD shapes from Plan 1

Microsoft Visio is the Microsoft 365 counterpart. Visio in Microsoft 365 is included in Microsoft 365 commercial plans as a web app. Visio Plan 1, at 5 USD per user a month paid yearly, adds software and database diagrams "including ERD and UML class diagrams". Visio Plan 2, at 15 USD per user a month paid yearly, adds the desktop app with offline and local files and "data connectivity with two-way sync", according to Microsoft's Visio plan comparison. Microsoft's comparison page names no reverse engineering of a database in any plan, so the ERD in Visio is drawn from its shapes.

Google Workspace teams draw schemas in Draw.io and connect tables by hand

Google Workspace has no database diagramming application. Teams that work in it use Draw.io, which is free, has "Apache 2.0 licensed source code", needs no account, and integrates with Google Drive, Docs and Slides as well as Microsoft SharePoint, OneDrive and Teams, Confluence, Jira, GitHub, VS Code and Notion.

Draw.io can turn SQL into entity shapes: Arrange → Insert → Advanced → SQL takes your CREATE TABLE statements and converts each table into an entity with its attributes. Its own guide then tells you to "rearrange and connect the entities" yourself, so the relationships are drawn by hand.

ChartDB renders a schema in the browser from one pasted query

ChartDB renders a schema in the browser from one query: you run the query ChartDB gives you, paste the result and it draws the diagram. ChartDB's pricing page lists a Free plan for one user and one database with up to 10 tables, self-hosted or in ChartDB's cloud. Pro costs 25 USD a month for one user and one database with up to 100 tables, and adds the interactive DBML editor and schema export. The Team plan, listed at 59 USD, covers 3 users and 5 databases with up to 200 tables each and adds real-time collaboration, auto-sync, database migration and a change log.

Pick the tool by what must stay true after the next release

Decide by what has to stay true after the next release. When the diagram has to match the database, and the design has to be reviewed with the code, run DbSchema: the diagram is read from the catalog, the design lives in a model file in Git, and a refresh shows what moved. When the deliverable is a picture for a meeting, Miro and Lucidchart draw it on a shared canvas, Visio draws it inside Microsoft 365, and Draw.io draws it for free. When you want a schema shown in a browser tab from one query, ChartDB does that.

To see your own schema the way the example above shows it, download DbSchema, connect it to the database whose diagram is out of date and reverse-engineer it: the Community Edition draws the tables and foreign keys. Saving the model to a file for Git, refreshing it from the database and exporting HTML5 documentation are in DbSchema Pro, which you can try for 15 days.

Frequently asked questions

What is the best alternative to Lucidchart for database diagrams?

DbSchema, when the diagram has to come out of the database. It connects over JDBC, reads tables, columns and foreign keys from the catalog, and keeps the design in a model file that a refresh compares with the database.

Does Microsoft have something similar to Lucidchart?

Microsoft Visio is the closest equivalent: Plan 1 includes ERD and UML class diagrams and Plan 2 adds the desktop app; the ERD is drawn from shapes rather than read from a database.

Is there a Google equivalent to Lucidchart?

Google has no database diagramming application, so teams on Google Workspace use Draw.io, which saves to Google Drive and turns pasted CREATE TABLE statements into entity shapes.

Can Miro or Lucidchart reverse-engineer a database?

Neither connects to a database. Lucidchart imports the result of a query you run yourself, and Miro's pricing page lists no database import. DbSchema reads the catalog directly through a JDBC driver.

Who are Lucid Software's main competitors for a database diagram?

DbSchema and ChartDB read a schema from the database or from a query result instead of from shapes, and DbSchema also writes the SQL when the design and the database differ. Miro, Microsoft Visio and Draw.io compete with Lucid on general diagramming.
