pettiSQLiteStudio (Letos) vs Petti
Looking for SQLiteStudio alternatives? The project is now named Letos. It remains a free, open-source SQLite tool; Petti takes a Mac-only approach with free viewing and licensed editing.
What SQLiteStudio / Letos is
Letos, formerly SQLiteStudio, creates, edits and browses SQLite databases on Windows, Linux and macOS. The project is GPL-licensed and states that it has no paid edition. Its current releases also include an ERD editor.
What Petti is
Petti is a native macOS SQLite viewer and editor built around a spreadsheet-style grid. It opens with a genuine read-only connection, loads rows in bounded pages, and includes Finder Quick Look previews of database metadata. Viewing is free; a license enables editing.
Key differences
| Dimension | Letos | Petti 1 |
|---|---|---|
| Platforms | Windows, Linux and macOS | macOS 14+, Apple silicon only |
| Focus | SQLite database work across platforms | Local SQLite files on Mac |
| Browse and edit data | Included free | Free viewing; licensed editing |
| ER diagrams | ERD editor in current releases | Not included in Petti 1 |
| Licensing | GPL, free and open source | Commercial editing license |
When Letos makes more sense
It is a practical starting point when you need free editing, open-source software, an ERD editor or a workflow shared with Windows and Linux colleagues.
When Petti may make more sense
Try Petti when your routine is opening a file in Finder, checking a table, and occasionally making a small correction. The read-only connection and explicit unlock make that boundary visible. Petti also previews table names and other database metadata through Quick Look.
Pricing and platforms
Letos has no paid edition. Follow its official download links for current platform builds. Petti’s current release requires an Apple silicon Mac running macOS 14 or later.
Petti’s regular price is US$14.99, with a US$9.99 launch offer for the first 100 purchases. A Petti 1 license includes 1.x updates; future major versions may be sold separately. Check Petti’s pricing and the checkout total before purchasing.
Try the workflow that matches your needs
Letos gives you a free cross-platform option. Petti gives you a focused Mac workflow you can evaluate without buying. Neither choice requires moving your SQLite data to a server; begin with a copy of a database you know and compare the tasks you actually perform.
