Sqemo

Getting Started

Start in the browser — no sign-up

Open the app and start modeling right away. Sqemo runs entirely in your browser: your work is autosaved locally (IndexedDB) moments after every change, and you can keep several projects side by side. Nothing leaves your machine until you sign in.

Model in business terms

Sqemo keeps two linked views of the same model: a logical model in your business language (“Customer”, “Order Item”) and a physical model with the actual table and column names. They stay connected by stable IDs, so renaming one side never orphans the other.

  • Add entities from the toolbar and describe them with logical names.
  • Switch views with the tabs above the canvas — logical and physical are two projections of one model, not two diagrams to keep in sync.
  • Draw relationships between entities and set cardinality in the inspector.
  • Search everything with Ctrl+K — entities, attributes, dictionary words.

Physical names are generated, not typed

When you type a logical name, Sqemo generates the physical name from your glossary and naming rules. Overriding a generated name is allowed — the override is marked and excluded from automatic regeneration. See Naming standards for how the generation works.

Work with files

Export the whole project as a .erd.json file — logical and physical models, glossary, and naming rules in one portable file you can commit to a repo or send to a colleague. SQL DDL and DBML also round-trip; see Import & export.

Sign in when you need more

An account adds server-saved ERDs, snapshots, realtime co-editing, and workspaces with a shared team standard. See Team collaboration and pricing for plan limits.
