AFFiNE vs Obsidian: which should you choose in 2026?

Last updated May 2026

Both AFFiNE and Obsidian believe your data should live on your device. Both are beloved by people who care about ownership, privacy, and not being locked into a SaaS platform. That's where the similarity ends.

AFFiNE is trying to be everything: docs, databases, and an infinite whiteboard canvas in one open-source app. It's ambitious, newer, and still evolving.

Obsidian is trying to be one thing perfectly: a markdown editor with bidirectional links, a graph view, and 1,600+ plugins that let you build whatever else you need. It's mature, proven, and deeply extensible.

The choice is between a newer tool that bundles more out of the box and an established tool that lets you build exactly what you want.

Side-by-side comparison

Where AFFiNE wins

The canvas. AFFiNE's edgeless whiteboard is a genuine differentiator. An infinite space with shapes, connectors, text blocks, embedded documents, and frames you can export as presentation slides. Brainstorm, diagram, storyboard, and present in the same workspace as your docs. Obsidian's Canvas exists but it's simpler: cards and connections on a spatial surface. For visual brainstorming and diagramming, AFFiNE's canvas is more capable.

Databases. AFFiNE has native databases with custom fields, table and kanban views, and filters. Obsidian has no native database. Dataview is a powerful community plugin, but it requires learning a code-like query language to approximate what AFFiNE provides out of the box.

Open source. AFFiNE's code is on GitHub. You can inspect it, fork it, contribute to it. Obsidian is closed source. Your data is open (plain markdown), but the software isn't. For people and organisations where open-source licensing is a requirement, AFFiNE is the only option between these two.

Self-hosting. Run AFFiNE on your own infrastructure. Full control over servers, data, and access. Obsidian doesn't offer self-hosting. Your data is local files, which is excellent for personal control, but for teams that need a shared, self-hosted workspace, AFFiNE provides that.

Collaboration. Real-time co-editing on cloud plans with comments. Obsidian has no native collaboration. Shared vaults via Git or synced folders are possible but require technical setup and aren't designed for real-time co-editing.

Block editor with rich formatting. AFFiNE's block editor is closer to the Notion-style experience: toggles, embeds, rich text without markdown syntax. Obsidian's editor is markdown. If you prefer writing in rich text without learning markdown, AFFiNE is more accessible.

Where Obsidian wins

Maturity and stability. Obsidian has been refined over years. The editor is fast. The features are stable. The community has stress-tested everything. AFFiNE is ambitious but younger. Performance can slow on large canvases. Features are being shipped rapidly, which means occasional rough edges.

The plugin ecosystem. 1,600+ plugins. Citation management, kanban, spaced repetition, calendar views, custom CSS themes, Dataview queries, graph analysis, AI integrations. If a feature doesn't exist, someone has probably built it. AFFiNE's plugin ecosystem is nascent.

Bidirectional links and graph view. Obsidian's linking model is its identity. Backlinks, unlinked mentions, and a visual graph that reveals the structure of your thinking over time. AFFiNE has page links but backlinks are still under development. No graph view. For people who think in connections, this is Obsidian's defining advantage.

Data format. Plain markdown files. Readable by any text editor, any operating system, any future tool. No proprietary format. No migration needed. AFFiNE uses its own internal format with markdown export available. The export works, but your working data isn't plain text files sitting in a folder the way Obsidian's is.

Daily notes. A core feature that opens a fresh note for each day. Daily journaling, quick capture, ongoing thinking. AFFiNE has no native daily notes.

Speed. Obsidian is fast. Vault with 10,000+ notes opens and searches in under a second. AFFiNE can slow down with large canvases and many pages.

Community. Obsidian has one of the most active communities in the tools-for-thought space. Forums, Discord, YouTube tutorials, template sharing, plugin development. AFFiNE's community is growing but smaller.

Price. Obsidian is free for personal use. AFFiNE is free for local use too, but Obsidian's free tier is more mature and feature-complete.

Where both fall short

Both are text-first. PDFs, video, audio recordings, slide decks, spreadsheets, images searchable by content. Neither tool extracts, indexes, or searches inside these file types. Both store them as attachments or embeds the system can't read.

Neither has semantic search. Obsidian has fast full-text search and regex. AFFiNE has full-text search across pages. Neither searches by meaning. You can't describe what you're looking for in your own words and find content that matches conceptually.

Neither AI understands your library. AFFiNE's AI helps you write. Obsidian's community AI plugins work on individual files. Neither answers questions across your entire knowledge base or maps relationships between content automatically.

Limited integrations. Obsidian has community plugins for many tools (Zotero, Git, Google Calendar), but they're maintained by volunteers. AFFiNE imports from Notion and Markdown, with a growing but thin integration landscape. Neither connects to Google Drive, Dropbox, or email in a way that creates a unified, searchable library.

Neither handles the "everything else." Meeting recordings, saved web articles with full content extraction, bookmarks, voice memos, emails. The content that doesn't start as text. Both tools were built for writing. Everything else is secondary.

A different path to the same goal

If you're choosing between AFFiNE and Obsidian, you care about your data being truly useful and connected. You're not a casual note-taker. You want your knowledge to compound.

Both tools approach this through architecture: build structure (AFFiNE's databases and canvas) or build connections (Obsidian's links and graph). Both require your effort to create and maintain the system.

Fabric achieves the same outcome through intelligence instead of architecture. You don't build databases or link notes manually. You save content, any file type, from any source. The AI maps relationships automatically. Semantic search finds things by meaning. Your knowledge compounds not because you maintained a system, but because the system maintains itself.

Fabric has a spatial canvas with live embeds (Figma, YouTube, Google Maps) and AI that understands what's on the board. It handles every file type natively: PDFs searchable to the page, video to the timestamp, images by visual similarity. Cross-platform search spans Google Drive, Notion, Dropbox, and your Fabric library from one place.

Fabric is cloud-hosted, not local-first. It's not open source. If those are hard requirements, AFFiNE or Obsidian is the right tool. But if the goal is knowledge that connects and compounds with minimal maintenance, Fabric gets there through a different path.

How to choose

Use AFFiNE if you want docs, databases, and a whiteboard canvas in one open-source, local-first app. You need self-hosting for your team. You value open-source licensing. You want visual brainstorming alongside your notes. You're comfortable with a product that's still maturing. And you're willing to trade Obsidian's plugin ecosystem for AFFiNE's built-in features.

Use Obsidian if you want a mature, fast, proven tool with maximum extensibility. You think in connections and want bidirectional links with a graph view. You value plain markdown files with zero vendor lock-in. You'll invest hours in plugins and configuration because the payoff is a system built exactly for you. You work alone. And you want the largest, most active community in the tools-for-thought space.

Try Fabric if you want your knowledge connected and searchable without building the system yourself. Intelligence over architecture. Every file type handled. Semantic search across everything. No setup. Generous free plan.

FAQs

Is AFFiNE more open than Obsidian?

In terms of source code, yes. AFFiNE is open source (GitHub, 60,000+ stars). Obsidian is closed source. In terms of data format, Obsidian is more open: plain markdown files readable by anything. AFFiNE uses its own format with markdown export. Different kinds of openness.

Does Obsidian have a canvas like AFFiNE?

Obsidian has Canvas (now a core feature). It's a spatial surface with cards and connections. AFFiNE's edgeless canvas is more capable for diagramming: shapes, connectors, presentation frames. Obsidian's is simpler but integrated into the linking/graph ecosystem. Fabric's canvas adds live embeds and AI awareness.

Which is faster?

Obsidian. Vaults with 10,000+ notes open and search in under a second. AFFiNE can slow down with large canvases. Both are local-first, but Obsidian's architecture is more optimised for speed at scale.

Can I self-host Obsidian?

No. Obsidian is a local app, not a server-based tool. Your files live on your device, but there's no self-hosted server for team access. AFFiNE supports self-hosting for teams.

Which has better AI?

Neither has strong AI. AFFiNE's is built-in but shallow (writing assistance only). Obsidian's comes via community plugins (variable quality). Fabric's AI is in a different category: contextual to your entire library across all content types.

Which is better for academic research?

Obsidian with the Zotero plugin for citation management and the graph view for mapping connections between papers. AFFiNE's canvas for visual brainstorming alongside documents. Fabric for AI that understands your PDFs, lecture recordings, and notes together. Different strengths for different parts of the research workflow.
