AFFiNE vs. AppFlowy vs. Anytype: Which Open-Source Notion Alternative Fits Your Workflow?

ByWorkTechJournal Editorial Team

AFFiNE, AppFlowy, and Anytype each promise to replace Notion without locking your data into a proprietary cloud. They’re all open-source or open-core, all local-first in some sense, and all capable of handling notes, databases, and project tracking. The differences that matter are in the workflows they support well, the collaboration model they use, and the tradeoffs they make between openness and convenience.

This comparison covers what each tool does well, where each one falls short, and how to decide which one fits a specific workflow without switching twice.

Quick decision guide

Before the detailed breakdown: if you’re short on time, here’s the practical match.

  • AppFlowy — best for solo users or small teams who want fast native apps, offline-first behavior, and a clean Notion-like interface without cloud dependency. Real-time collaboration is less mature than AFFiNE’s.
  • Anytype — best for individuals who prioritize privacy and want a decentralized, device-local system. Works well for personal knowledge management. Object-based model has a steep learning curve. Team collaboration features are limited compared to the others.
  • AFFiNE — best for teams that need real-time collaborative editing combined with whiteboard-style visual planning. Handles Notion migrations most faithfully. More complex than AppFlowy; requires more setup for self-hosting.

None of these is a universal upgrade from Notion. Each one makes tradeoffs that Notion doesn’t. Evaluate based on your specific workflow for the next 12 months, not based on feature lists.

Architecture: what makes each tool different under the hood

AppFlowy is built with Rust and Flutter, which makes it one of the fastest note-taking apps in this category on desktop. Large lists scroll without lag. The app loads quickly. The tradeoff: being native-first means the web experience is secondary — browser-based quick access or cross-device web use isn’t AppFlowy’s strength.

Anytype runs on the Any-Sync protocol using IPFS (InterPlanetary File System) for a peer-to-peer data model. Everything in Anytype is an “Object” — a task, a note, a person — connected in a graph rather than a hierarchy of pages. Data lives on your devices and encrypted backup nodes, not a central server. Sync works peer-to-peer, which means both devices need to be online simultaneously at some point for changes to propagate. Sync conflicts can occur if devices aren’t online together.

AFFiNE uses TypeScript and Rust with CRDTs (Conflict-free Replicated Data Types) for real-time collaboration. CRDTs let two users edit the same document offline, then merge changes without conflicts when they reconnect. This is the same architecture used by collaborative tools like Figma. AFFiNE supports both a local desktop app and browser-based access, and offers Google Docs-style cursor-tracking collaboration.

Note-taking and the canvas factor

This is where the tools diverge most clearly in day-to-day use.

AppFlowy feels like a clean Notion clone structurally. Pages, grids, kanban boards — all well-implemented. If you need to add a diagram or visual element next to your text, you’re constrained to the block format. AppFlowy doesn’t have a freeform canvas mode.

Anytype uses an object-based model that requires you to define the type of every item you create. This is powerful for building a personal knowledge graph but adds friction to quick capture. Getting from “I have an idea” to “it’s stored” involves more steps than in AFFiNE or AppFlowy. The “Set” and “Collection” views are flexible, but they require setup before they’re useful.

AFFiNE has an “Edgeless Mode” — a freeform whiteboard that exists on the same canvas as your documents. You can start a project brief as a text document, switch to Edgeless, draw a flow diagram around the text, add sticky notes, and link visual elements back to structured pages. For creative workflows or planning sessions that move between writing and diagramming, this is genuinely different from the other two.

Migrating from Notion

If you’re coming from Notion with an existing workspace, migration quality matters.

AppFlowy handles basic text and kanban boards well on import. Complex relational databases typically require manual cleanup. Some Notion database properties don’t transfer cleanly.

Anytype tries to convert Notion blocks into Anytype Objects during import, which creates structural mismatches. Expect to spend significant time redefining relationships between pages. Not recommended if you have a large, structured Notion workspace.

AFFiNE offers the most faithful Notion migration. Because both are block-based, layout, headers, and images preserve well. AFFiNE includes a dedicated importer for HTML and Markdown exports from Notion.

Collaboration

AppFlowy: Sync exists, but real-time concurrent editing (seeing a colleague’s cursor move) is still maturing. Good for teams where members primarily work independently and sync changes periodically. Not yet suitable for teams that need live co-editing.

Anytype: Sharing and collaboration features are available but limited compared to the others. The P2P sync model makes real-time team collaboration harder to implement reliably. Currently more suited to individual use with occasional sharing.

AFFiNE: Built for collaboration from the ground up. Multiple users can edit the same document or whiteboard simultaneously. CRDT-based conflict resolution handles offline edits cleanly. The closest of the three to Google Docs-style team editing.

Self-hosting and data ownership

All three are local-first, but “local-first” means different things in practice:

  • AppFlowy: Open-source core, extensive self-hosting options. Full control for developers who want to run their own infrastructure. Cloud services are being introduced for those who don’t want to self-host.
  • Anytype: Data stored locally on devices plus encrypted backup nodes. P2P network; Anytype doesn’t see your data. Free during beta. Future monetization expected around backup node storage and larger shared spaces.
  • AFFiNE: Docker container available for self-hosting. Free Pro tier for individuals. Paid plans cover cloud storage and advanced team collaboration features. Commercial cloud option available for teams that want GDPR compliance without infrastructure management.

Who should not switch yet

All three tools have areas where they’re not ready to replace Notion for certain use cases:

  • Teams that need guaranteed SLAs or enterprise admin controls — none of these offer that at Notion’s level
  • Teams that rely heavily on Notion’s third-party integrations (Slack, GitHub, Jira, Zapier) — integration ecosystems are smaller here
  • Teams that need advanced database automations or API-based workflows built around Notion — port cost may be high
  • Non-technical teams who need predictable onboarding — Anytype in particular has a learning curve that can slow adoption

How to decide

Before committing: spend 20 minutes building the same mini-workspace in each tool you’re considering. Create a project brief, a task list, a simple table or database, a meeting note, and export a backup. The one that takes the least effort to complete that circuit is likely the right fit for your workflow — not the one with the most impressive feature list.

Avoid switching if your current workspace is stable and the appeal is primarily novelty. Migration costs are real, and the productivity loss during transition is rarely accounted for in tool evaluations.
