9 Best Database Design Tools of 2026

1. 1

   dbdiagram.io

   A browser-based ER diagram tool where you write the schema in DBML code and the diagram draws itself, with dbdocs publishing included.

   8.8overall

   A browser-based ER diagram tool where you write the schema in DBML code and the diagram draws itself, with dbdocs publishing included.

   Best fordevelopers who prefer typing a schema to dragging boxes

   Adoption data

   3Mdbdiagram.io's home page reports that more than 3 million diagrams have been created with the tool.

   dbdiagram.io, dbdiagram.io, Database Relationship Diagrams Design Tool (2026): “Over 3M diagrams created from around the world”

   dbdiagram.io treats a database schema as code. You type tables, columns and references in DBML, and the ER diagram updates beside the editor, which suits developers who already think in CREATE TABLE statements. The free plan is generous for solo work: up to 10 diagrams and doc projects, SQL import and export, image export to PDF, PNG and SVG, and public sharing. Every plan also includes dbdocs, so the same schema can be published as browsable documentation, and RunSQL, a browser SQL playground. Personal Pro costs $8 per month on annual billing and removes the diagram cap, adds private and password-protected sharing and tools for large schemas such as table groups and detail levels. Team costs $75 per month for three editors, with extra editors at $5 per month and a 7-day trial. The limits are real: free and Personal Pro plans have one editor, and version history needs a paid plan. The vendor reports more than 3 million diagrams created.

   Strengths

   • +Free plan covers up to 10 diagrams and doc projects with unlimited viewers
   • +Personal Pro is $8 per month on annual billing, the lowest paid plan in this list
   • +Students, teachers and researchers can get Personal Pro free for 12 months

   Limitations

   • −Free and Personal Pro plans allow a single editor
   • −Version history is not included on the free plan
   • −Code-first editing has a learning curve for people who want a drag-and-drop canvas

   Summarydbdiagram.io is the best database design tool for most developers because the free plan covers 10 diagrams and Personal Pro costs $8 per month billed annually. Teams that need several editors on one canvas should compare its $75 Team plan with DrawSQL and ChartDB.

2. 2

   Lucidchart

   A general cloud diagramming app from Lucid Software that can build ER diagrams by hand, from a live database import or with Lucid AI.

   8.5overall

   A general cloud diagramming app from Lucid Software that can build ER diagrams by hand, from a live database import or with Lucid AI.

   Best forteams that want ER diagrams in the same tool as their other diagrams

   Adoption data

   100M+Lucid Software reports more than 100 million individual users across its products, including Lucidchart.

   Lucid Software, About Lucid (2026): “100M+ individual users”

   Lucidchart is the pick when database diagrams are one part of a wider documentation habit. Lucid's ERD guide says you can build an entity-relationship diagram by hand, by importing a live database or by asking Lucid AI for an editable draft, and the same canvas also holds network maps, flowcharts and process diagrams. That breadth is also the limit: Lucidchart draws the model, but it is not a modeling tool that compares a design with a live database and writes the migration. The free plan is narrow, with 3 editable documents and 75 shapes per document, which a mid-sized schema can exceed. Individual costs $9 per month billed yearly and removes those caps, and adds Visio import and export. Team costs $10 per user per month billed yearly and adds revision history, password-protected publishing and integrations with Confluence, Jira and Microsoft 365. Lucid reports more than 100 million individual users and says it works with 99% of the Fortune 500.

   Strengths

   • +Largest published user base in this list, at 100 million plus individual users
   • +One subscription also covers flowcharts, architecture and process diagrams
   • +Free plan needs no credit card

   Limitations

   • −Free plan is capped at 3 editable documents and 75 shapes per document
   • −A general diagramming app, not a dedicated data modeler with schema synchronization
   • −The 7-day trial requires payment details at sign up

   SummaryLucidchart is the best choice for teams that already diagram everything in one app because it imports a live database into an editable ERD and costs $9 per month for an individual. Pick a dedicated modeler if you need DDL generation and schema sync.

3. 3

   ChartDB

   An open source database diagram editor that imports a full schema with one query, with a hosted cloud version and paid team plans.

   8.4overall

   An open source database diagram editor that imports a full schema with one query, with a hosted cloud version and paid team plans.

   Best fordevelopers who want a free, self-hosted ER diagram editor

   Adoption data

   23.1kChartDB's open source repository on GitHub shows about 23,100 stars.

   GitHub, chartdb/chartdb repository (2026): “Stars 23.1k stars”

   ChartDB is the open source entry in this list. Its import works by running one vendor-written query against your database and pasting the result, so the tool never needs your credentials, and the diagram covers MySQL, MariaDB, PostgreSQL, SQL Server and SQLite. You can edit tables and relationships, add subject areas and notes, and export DDL in your preferred SQL dialect or an image. The self-hosted edition is free and keeps data on your own servers. The hosted free plan is small, with one database and up to 10 tables, and Pro at US$25 per month raises that to 100 tables with a DBML editor and schema export. Teams starts at US$59 and adds real-time collaboration, auto-sync with the live database, an AI assistant, versioning and Snowflake and BigQuery support. The GitHub repository shows about 23,100 stars, the strongest open source signal among these tools.

   Strengths

   • +Open source under the AGPL-3.0 license, so it can be self-hosted at no cost
   • +Import works from a query result, without giving the tool database credentials
   • +Yearly billing is up to 40% cheaper than monthly

   Limitations

   • −Hosted free plan allows 1 database and up to 10 tables
   • −Pro is limited to 1 user and 100 tables per database
   • −Real-time collaboration and auto-sync need the Teams plan

   SummaryChartDB is the best free option for teams that can self-host because the open source edition costs nothing and imports a schema with one query. Use the hosted Teams plan from US$59 if you want real-time collaboration without running it yourself.

4. 4

   DbSchema

   A desktop database design and management tool from Wise Coders that models schemas offline, shares designs through Git and synchronizes them with live databases.

   8.2overall

   A desktop database design and management tool from Wise Coders that models schemas offline, shares designs through Git and synchronizes them with live databases.

   Best forarchitects who model offline and deploy changes to real databases

   DbSchema covers the full design loop rather than only the picture. It connects to a live database, draws a diagram for each schema, and lets you design new tables, keys and indexes on top. The Pro edition saves the model to a file you can work on offline, shares it through Git with side-by-side merges of conflicting edits, compares the design with a live database and shows the SQL for each change before it runs. It also publishes HTML5, PDF and Markdown documentation. The Architect edition adds logical and conceptual design before you pick a database. The free Community edition connects, reverse-engineers, draws diagrams and runs SQL, but cannot save a design to a file. On the USD purchase page, Pro costs $294 one-time with the first year of upgrades included, or $29.40 per month; Personal and Education tabs list lower prices. Every download starts with a 15-day trial. Wise Coders does not publish a user count, so adoption scores lower.

   Strengths

   • +Community edition is free forever for any use
   • +Pro is available as a perpetual license, yours to keep
   • +Works offline and stores the model in a file

   Limitations

   • −Desktop app, so there is no browser canvas for quick sharing
   • −Logical and conceptual design need the pricier Architect edition
   • −No published user count to back adoption

   SummaryDbSchema is the best choice for architects who deploy their designs because it compares a Git-shared model with a live database and generates the change script. Pro costs $294 once or $29.40 per month on a Business license.

5. 5

   Navicat Data Modeler

   A desktop data modeling tool from Navicat that works across conceptual, logical and physical models for eight database platforms.

   8.1overall

   A desktop data modeling tool from Navicat that works across conceptual, logical and physical models for eight database platforms.

   Best forarchitects who want conceptual, logical and physical models in one desktop app

   Adoption data

   180,000Navicat reports more than 180,000 registered customers in 138 countries across its product line, not only Data Modeler.

   Navicat, About Navicat (2026): “over 180,000 registered customers across 7 continents and 138 countries”

   Navicat Data Modeler is a desktop modeler for architects who move between abstraction levels. Its current version puts conceptual, logical and physical models in one hybrid workspace, so logical entities and physical objects such as tables, views and functions can sit side by side on the same canvas. It supports MySQL, PostgreSQL, MongoDB, MariaDB, SQL Server, Oracle, SQLite and Snowflake, which is broader than most tools here, and it reverse-engineers live databases, exports models to SQL, compares models and builds a data dictionary. The license is perpetual and per user, can be used on Windows, macOS or Linux, and includes one year of maintenance; after that, upgrades, live chat and support need a renewed plan. Navicat also lists a free Lite edition and a cheaper Non-Commercial edition for education and non-profits. The store page showed prices only after rendering, so we mark the USD price as pending. Navicat reports more than 180,000 registered customers across all its products.

   Strengths

   • +Covers MongoDB and Snowflake as well as relational engines
   • +Perpetual license with one year of maintenance included
   • +A free Navicat Data Modeler Lite edition is listed by the vendor

   Limitations

   • −USD price could not be verified from our location, so check the store
   • −Upgrades and support need an active maintenance plan after the first year
   • −Desktop only, with no browser editor for quick sharing

   SummaryNavicat Data Modeler is the best desktop choice for mixed SQL and NoSQL estates because one model covers eight platforms including MongoDB and Snowflake. Check the store for the current USD price before you compare it with DbSchema.

   Redgate Data Modeler

   A browser-based collaborative data modeler, formerly Vertabelo, now sold by Redgate Software.

   8.1overall

   A browser-based collaborative data modeler, formerly Vertabelo, now sold by Redgate Software.

   Best fordatabase teams that model together in the browser

   Adoption data

   200,000Redgate says 200,000 people rely on its software worldwide; this figure covers all Redgate products, not only Data Modeler.

   Redgate Software, Redgate, Database DevOps solutions (2026): “200,000 people rely on Redgate worldwide”

   Redgate Data Modeler is the former Vertabelo Data Modeler, which Redgate acquired and now sells under its own name. It runs in the browser, so a team edits one shared model with real-time collaboration and built-in versioning instead of passing files around. It targets PostgreSQL, MySQL, SQL Server, Oracle and more, reverse-engineers existing databases, validates the model as you work and generates both DDL and migration scripts. Standard costs $189 per user per year and covers physical design with up to 20 models and 100 tables per model. Pro costs $303 per user per year and adds logical design, unlimited models and tables, and API access. Both have a 14-day trial, and there is no permanent free plan. SQL Server teams can also get Data Modeler Pro inside SQL Toolbelt Essentials. Redgate reports that 200,000 people rely on its software, but that figure covers its whole product range.

   Strengths

   • +Nothing to install, and models are shared by link
   • +Generates migration scripts as well as DDL
   • +Can be bought inside SQL Toolbelt Essentials for SQL Server teams

   Limitations

   • −No permanent free plan, only a 14-day trial
   • −Standard is capped at 20 models and 100 tables per model
   • −Logical design needs Pro at $303 per user per year

   SummaryRedgate Data Modeler is the best browser-based choice for database teams because it pairs real-time collaboration with DDL and migration script generation from $189 per user per year. Solo developers on a budget will get more from dbdiagram.io or ChartDB.

   Luna Modeler

   A desktop data modeling tool from Datensen for relational databases, sold as a one-time license.

   8.0overall

   A desktop data modeling tool from Datensen for relational databases, sold as a one-time license.

   Best forfreelancers who want a pay-once desktop modeler

   Adoption data

   85Datensen says Luna Modeler is used by customers in more than 85 countries; it does not publish a user count.

   Datensen, Luna Modeler, data modeling tool for popular databases (2026): “Trusted by customers in +85 countries worldwide.”

   Luna Modeler is a pay-once desktop modeler for relational databases. You can start from a blank canvas and generate DDL for Oracle, PostgreSQL, MySQL, SQL Server, MariaDB or SQLite, or connect to an existing database, including cloud hosts such as Supabase and Neon, and reverse-engineer it into a diagram. It supports conceptual, logical and physical models, sub-diagrams and notes, and exports interactive HTML or PDF documentation. Comparing the model with a live database and generating a synchronization script is part of the Professional edition. Pricing is simple: Basic is $99 once, Professional is $189 and Ultimate is $349, with Ultimate adding a schema navigator, a folder-based format for team work and a command line interface. There is a 14-day trial with no card. The app works offline on Windows, macOS and Linux. Datensen says it has customers in more than 85 countries but publishes no user count, so its adoption score is conservative.

   Strengths

   • +Basic edition costs $99 once, with unlimited projects and tables
   • +Runs offline on Windows, macOS and Linux, so data stays on your device
   • +14-day trial needs no credit card

   Limitations

   • −Schema synchronization and secure SSH/TLS connections start at the $189 Professional edition
   • −No real-time collaboration; team work uses a folder-based format in Ultimate
   • −No published user count, so adoption scores lower

   SummaryLuna Modeler is the best choice for freelancers who dislike subscriptions because the Basic edition is a $99 one-time license with unlimited projects and tables. Pay $189 for Professional if you need schema synchronization.

8. 8

   ER/Studio

   An enterprise data modeling and metadata platform from Idera for conceptual, logical and physical models with governance integrations.

   7.5overall

   An enterprise data modeling and metadata platform from Idera for conceptual, logical and physical models with governance integrations.

   Best forenterprise data architects with governance requirements

   ER/Studio is built for data architecture teams rather than individual developers. It models conceptual, logical and physical layers across major database platforms, adds AI-assisted modeling and reusable standards, and turns models into database schemas with ongoing change management. Its main difference from the other tools here is governance: models connect to business glossaries and tools such as Microsoft Purview and Collibra, and the Enterprise edition adds a web portal for collaboration and metadata exchange across platforms. Version 21.2 adds modeling for Microsoft Fabric warehouses and lakehouses, and Idera is actively courting PowerDesigner users as that product reaches end of life. The price reflects the audience: Data Architect costs $2,687 per user and Data Architect Pro $3,693 per user as a subscription, before taxes, and Enterprise is quote only. A free trial is offered. Idera does not publish a user count for ER/Studio, so adoption scores conservatively.

   Strengths

   • +Deepest governance and metadata feature set in this list
   • +Data Architect Pro adds change management and real-time team collaboration
   • +Clear online prices for the two workstation editions

   Limitations

   • −Most expensive tool here at $2,687 per user for the entry subscription
   • −Enterprise edition with the web portal requires a quote
   • −No permanent free plan and no published user count

   SummaryER/Studio is the best choice for enterprise data architects because it links models to governance tools such as Purview and Collibra. At $2,687 per user it is too expensive for developers who only need ER diagrams.

   DrawSQL

   A browser-based database diagram tool for product teams, with SQL import, real-time multiplayer editing and an AI schema reviewer.

   7.4overall

   A browser-based database diagram tool for product teams, with SQL import, real-time multiplayer editing and an AI schema reviewer.

   Best forsmall product teams that review schemas together

   DrawSQL is aimed at product teams that discuss schemas together. You paste CREATE TABLE statements and get an auto-laid-out diagram, then group tables by domain, add sticky notes and start comment threads on a table. Exports cover SQL for MySQL, PostgreSQL and SQL Server, Laravel migrations and JSON, and 200+ templates give starting points for SaaS, ecommerce and CRM schemas. DrawSQL AI, included from Starter with 500 credits per month, flags missing indexes and inconsistent naming and drafts tables from a description. The free plan has no time limit but diagrams are public and capped at 15 tables. Starter costs $19 per month for 10 private diagrams of up to 50 tables, Growth costs $59 per month for up to five users with real-time multiplayer, and Large costs $179 per month for 25 users. Engine support is limited to MySQL, PostgreSQL, SQL Server and MariaDB, and DrawSQL publishes no user count.

   Strengths

   • +Free plan has no time limit and includes SQL import and the full editor
   • +Laravel migration export suits PHP teams
   • +Diagrams embed in Notion and Confluence

   Limitations

   • −Supports only MySQL, PostgreSQL, SQL Server and MariaDB
   • −Free diagrams are public and capped at 15 tables
   • −No published user count, so adoption scores lowest

   SummaryDrawSQL is the best choice for small product teams because its $59 Growth plan gives up to five people real-time editing on unlimited private diagrams. Teams on Oracle, SQLite or NoSQL databases should look elsewhere.
