AFFiNE

AFFiNE is an open-source, local-first workspace that combines a block-based document editor with whiteboards and knowledge-base style organization. It targets the “Notion + Miro” workflow, offering flexible pages, databases/collections, and collaborative editing while keeping offline use and local storage as first-class.

Key Features

• Block-based editor for pages and documents (rich text, blocks, embeds)
• Whiteboard/canvas for freeform brainstorming and diagrams
• Knowledge organization with pages, collections/databases, and backlinks-style navigation
• Local-first workflow with offline use; optional sync via AFFiNE Cloud or self-hosted server
• Real-time collaboration (multi-user) on supported deployments
• Import/export options for migrating content (varies by format/version)
• Cross-platform apps (desktop) and web app distribution

Use Cases

• Personal knowledge management for notes, journaling, and structured research
• Team documentation/wiki with collaborative editing and shared spaces
• Whiteboarding for planning, brainstorming, and project discovery sessions

Limitations and Considerations

• Some advanced “Notion-like” database automations/integrations may be less mature than commercial incumbents.
• Feature parity and stability can vary between desktop, web, and server deployments as the project evolves.

AFFiNE is a strong fit for users who want an offline-capable workspace that blends documents and canvases, while still supporting collaboration when a sync server is used. It is especially compelling for teams seeking a unified notes+whiteboard toolchain without relying on proprietary SaaS defaults.
