What Lazurite Offers Beyond Bluesky

Available Now

• Semantic Search: On-device vector embeddings (all-MiniLM-L6-v2) let you search saved and liked posts by meaning, not just keywords.
• Post Scheduling: Write posts now, publish them later.
• Follow Audit: Bulk-analyze your follows to find deleted, deactivated, suspended, or blocking accounts. Batch unfollow in one tap like clean follows
• Constellation Integration: See who has blocked you and which lists you appear on, powered by Constellation backlinks.
• AT Protocol Dev Tools: Browse any user's PDS repository, inspect collections and individual records as JSON, like an in-app pds.ls.
• Rich Theming: Five full palettes (Lazurite™️², Rose Pine, Catppuccin, Nord, Oxocarbon), each with light and dark variants, built on Material 3.
• Offline First: First page of feeds is cached locally; drafts, search history, and saved posts persist in an on-device database.
• Local Drafts: Auto-saved to the database, surviving crashes and force-closes. Multiple drafts per account with full reply/quote/media context.
• Layout Options: Toggle between Card and Compact feed views. Configure thread auto-collapse depth (off, 1–6 levels).
• In-App Logs: Filter by level, full-text search, share or export, useful for debugging and AT Protocol development.

• Markdown Posts: Toggleable Markdown rendering in post bodies.
• Firehose & Jetstream Viewers: Live AT Protocol event streams inside Dev Tools.
• Auto-Threading: Automatically split long posts into threaded replies.

The project follows a feature-first architecture layered with a core module:

• lib/core/: Shared infrastructure, database, router, and themes.
• lib/features/: Feature-specific logic (Auth, Feed, Search, Profile, etc.).
  • <feature>/bloc/: Business logic components.
  • <feature>/presentation/: UI screens and widgets.
  • <feature>/data/: (Optional) Feature-specific repositories or models.
