Tine

Tine is a desktop and mobile outliner designed to work alongside Logseq. It reads and writes the same Markdown graph format, allowing users to switch between the two applications on identical files without import/export steps or vendor lock-in. The project describes itself as built on a native shell with Rust-based parsing and indexing, plus a reactive frontend that avoids heavy re-rendering.

Tine targets users with large note graphs who want faster performance. It supports core features like queries, callouts, namespaces, and properties while adding split-view panes and tabbed navigation. Available on Linux, macOS, Windows, Android (via F-Droid), and iOS (beta), it's free and open-source under AGPL-3.0.
