Lopo Studio, a local-first SQL client for Windows

Field notes

The application targets Windows 10 and 11 and connects directly to PostgreSQL and MySQL servers while opening SQLite and DuckDB files locally. Its workflow includes multi-tab editing, schema inspection, paginated data browsing, CSV import with type detection and optional primary keys, and exports to CSV, JSON, DDL, or portable schema snapshots. The page states that passwords and SSH key passphrases use Windows Credential Manager and that normal use requires neither an account nor a constant internet connection.
