Schemity automates sql to erd translation

Schemity's desktop ERD application parses PostgreSQL, MySQL, MariaDB, SQL Server, SQLite, or Supabase dumps and renders a full entity-relationship diagram without manual entry [Dev.to]. It also watches diagram edits and produces a reviewed SQL migration diff that can be applied directly to the database. The tool stores the parsed schema as plain JSON, never sending data to a cloud service, satisfying NDA constraints for many enterprise teams. The release introduces a right-click export that outputs either a single entity's DDL or the entire schema's SQL, useful for PR comments or documentation snapshots [Dev.to]. Schemity supports reverse-engineering live connections in addition to static dump files, allowing users to paste a CREATE TABLE script and see foreign-key relationships. When a table is renamed or a column added in the diagram, Schemity emits the exact ALTER TABLE statements required, grouped by entity, and presents them for review before execution [Dev.to]. Manual transcription is error-prone, with at least one typo per forty tables, according to the author's informal audit. Schemity's bidirectional sync prevents drift by generating migration diffs from diagram edits, keeping the visual model and the live database in lockstep. Offline processing protects sensitive schemas, as the parser runs locally and never contacts external servers, making it suitable for teams handling regulated data [Dev.to].
