The ERD tool that enforces your team's naming standards
Design databases with a shared glossary, not guesswork. Model in business terms — consistent physical names for tables and columns are generated by your team's naming rules.

Sound familiar?
Every team ends up with three names for the same thing. Code review catches some of it. The rest ships to production.
user_id userId usr_id user_no
Naming conventions in a wiki don't enforce themselves. Sqemo turns them into rules that run on every column you add.
Glossary in, consistent schema out
-
1. Define your glossary once
Map business terms to physical words and abbreviations — "customer" →
cust, "identifier" →id. -
2. Model in business language
Name entities and attributes the way your domain experts talk. Logical and physical models stay linked.
-
3. Physical names, generated
Table and column names follow your naming rules automatically. Terms missing from the glossary get flagged, not shipped.
Everything else an ERD tool should do
-
Team glossary & naming rules
A shared dictionary and rule engine keep every diagram on the same standard — with a compliance report to prove it.
-
Logical / physical modeling
Two connected tiers, like the big modeling suites — without the license fees or the installer.
-
7 SQL dialects + DBML
Import and export MySQL, PostgreSQL, Oracle, CUBRID and more. DBML both ways.
-
Team standards & live collaboration
Share glossaries and rules across a workspace, propose changes through a suggestion queue, edit diagrams together in real time.
-
MCP server for AI workflows
Let Claude or any MCP client read and edit your ERDs — modeling assistance with your naming standard still enforced.
-
Free to start, nothing to install
Runs entirely in the browser. Local projects need no account at all.
