Things to know

• !The license is source-available with additional conditions, not a standard open-source license, and the metadata shows no detected license.
• !It is a single-user local application with no user accounts, so it is not suited to shared or multi-user access.
• !Losing the encryption key makes stored datasource passwords and AI API keys unreadable, so it must be backed up.
• !Custom JDBC drivers are executable Java code and must come from trusted sources.
