ER Designer review
A focused ER learning tool with classroom workflows and export options.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
ER Designer is a browser-based database design tool for students, teachers, independent users, and businesses that need to model entity-relationship concepts. Its core workspace supports conceptual ER diagrams in classic, oval, and tabular styles, with guided schema restructuring and automatic logical-schema generation. Educational workflows extend beyond diagram editing: teachers can create classes, assign work with attachments, and monitor submissions and progress, while students receive class access, submissions, and an editor. Users can save and manage projects after signing in and export diagrams as JSON, PNG, or PDF.
The product’s strongest fit is education rather than end-to-end database engineering. Student access and the Teacher free tier are presented as free, including class management, assignments, attachments, submission monitoring, and progress tracking. The pricing page also lists User, Teacher, Organization, and Student plans, with paid annual User and Teacher subscriptions shown alongside free access options. That role-based structure gives instructors and learners a practical starting point, while independent users and organizations should review the applicable plan before choosing an account type.
ER Designer is a good choice when the main goal is explaining, creating, reviewing, and submitting ER models in a web browser. JSON import and export support project portability, and PNG and PDF exports help with sharing diagrams outside the editor. Google and GitHub are listed integrations. The product is less suitable for teams that need database reverse engineering, forward engineering, SQL export, deployment, collaboration, or version history. Choose it for structured ER education and focused conceptual modeling; choose an alternative when the workflow must continue from diagrams into database implementation.
