Tasks

Local-first, collaborative notes and tasks—built for offline reliability.

Tasks is a local-first, collaborative notes and tasks app built for reliability, offline resilience, and open collaboration. It’s designed for users who want full control over their data while still benefiting from modern real-time collaboration.

Packaged as a lightweight Progressive Web App (PWA), Tasks works offline by default and syncs efficiently when connectivity is available.

What it does

• Local-first storage
  Data is cached using IndexedDB and service workers, allowing the app to function fully offline.

• Real-time collaboration

  Peer-to-peer syncing with Yjs and WebRTC enables collaborative editing without centralized servers.

• Offline-first sync model
  Changes sync efficiently between devices using PocketBase subscriptions, with future plans for ActivityPub federation.

• Open source by design

  Licensed under AGPL-3.0, ensuring the project remains transparent, forkable, and user-respecting.

• Progressive Web App
  Installable on desktop and mobile—no app stores, no lock-in.

• Flexible content model

  Notes and tasks are stored as blocks, supporting rich text, embedded files, and quick-action templates.

• Dynamic theming
  Customizable CSS-based themes adapt the UI without heavy frameworks.

Architecture overview

• Frontend: Vanilla TypeScript + Web Components
• Collaboration layer: Yjs (CRDT) + WebRTC + IndexedDB persistence
• Optional backend: PocketBase for presence and event subscriptions
• Deployment: Optimized for edge hosting (Vercel, Cloudflare)

Why it exists

Task and note apps often trade control and durability for convenience. Tasks takes the opposite approach: offline-first, user-owned data, and collaboration that doesn’t depend on a central service.

It’s an exploration of what practical, everyday software looks like when local-first principles are treated as a foundation rather than a feature.
