SwashbucklerDiary is an open-source, cross-platform local diary app built with Blazor (Hybrid, Server, and WebAssembly) and .NET MAUI. All data is stored locally with no network required, supporting Android, Windows, macOS, Web, and Linux.

Use cases

• keep a private offline diary on my phone and desktop
• write journal entries in markdown with live preview
• diary app that stores everything locally without an account
• back up my journal via webdav
• sync diary entries between devices on the same network
• journal app with tags, mood, weather, and location
• export diary entries to multiple formats
• open-source cross-platform journaling app

When to choose

• you want a privacy-focused, local-first diary with no cloud dependency
• you need one journaling app across Android, Windows, macOS, Linux, and Web
• you want markdown support with math, charts, mind maps, and media attachments
• you prefer open-source software with self-controlled data

When to avoid

• you need cloud sync across different networks or multi-device cloud backup beyond webdav
• you want collaborative or shared journaling
• you need a mobile-first native UI rather than a Blazor-based interface
