Using Petti
Getting started with Petti
Install Petti on an Apple silicon Mac, open a SQLite file, browse and search tables, run a query, and activate a license when you want to edit.
Editing and moving data safely
Understand immediate saves, the read-only lock, cell undo, CSV import and export scopes in Petti. Learn when to capture a snapshot before changing SQLite data.
Preview files and cell values
Use Finder Quick Look and Petti cell previews for SQLite. Inspect JSON, text, images and bytes while understanding truncated previews and interpretation limits.
Inspect changes
Snapshots and What Changed?
Capture a SQLite snapshot, manage history, compare before and after states, and use What Changed? in Petti. Understand storage costs and comparison limits.
Database Info and live databases
Inspect SQLite metadata, WAL companions and change notices in Petti. Refresh safely, recognize replaced files, and capture stable snapshots of live databases.
