What both publish
| Fact | OpenDBD | Schemity |
|---|---|---|
| Local storage | Projects, schemas, chat, and notes are stored in IndexedDB in the user's browser, and the app says it does not sync the workspace to remote servers. | Schemity stores work as plain JSON files on the user's machine, which can be version-controlled with Git. |
| Privacy | The maker says no account is required and schemas and API keys stay in the browser. | The desktop app has no cloud backend, accounts, analytics, or telemetry; it transmits an automatically generated machine ID and country code for license verification. |
