What it is

Lumbre is a weekly planner inspired by graph paper. Each task lives on a day or in a list, and the week reads at a glance, stacked or in columns.

How it's built

  • Local-first: data lives on the device (TinyBase over IndexedDB) and syncs over WebSocket with a custom server (Postgres and object storage).
  • One codebase, six platforms: SvelteKit for the web and the PWA, and Tauri 2 for iOS, macOS, Android and Linux.
  • Soplo: plan your day by speaking, with transcription and a plan you review before applying it.

Around Lumbre

  • Lumbre for Obsidian: a plugin that shows Lumbre's tasks inside the vault without copying them into Markdown.
  • Lumbre MCP: a connector so Claude, Codex and other MCP clients can add and query tasks from a conversation.
