VisitComet vs Turtl
What both publish
| Fact | Comet | Turtl |
|---|---|---|
| Encryption | The site says note content is encrypted before sync uploads, so relay and Blossom servers see ciphertext rather than content. | Turtl encrypts data on the client before transmission, so stored server data remains unreadable without users' keys. |
| Free plan | Yes | Yes |
| Integrations | The project README describes encrypted sync with Nostr and encrypted blob storage with Blossom. | The official feature and download pages describe Chrome and Firefox bookmarking extensions and Android sharing, but do not list other integrations. |
| License | The site states Comet is open source under the MIT License. | The desktop, core and browser-extension repositories identify the GNU GPL version 3 license, while the server repository uses AGPL-3.0. |
| Markdown | Notes use Markdown, which the site describes as portable and exportable. | Turtl supports Markdown formatting and TeX mathematical expressions in notes. |
| Offline access | Yes | Yes |
