Obsidian vs Roam Research: which should you choose in 2026?

Last updated May 2026

Roam Research invented the category. Bidirectional links, daily notes, block references, the graph view. In 2020, Roam changed how people thought about note-taking. Then Obsidian took those ideas, made them local-first, made them free, and added 1,600 plugins. By 2026, the audience has largely shifted.

Roam is still a genuinely powerful tool for networked thought. The block reference system and query language remain unique in their depth. But at $15/month with no free plan, cloud-only storage, and a development pace that has slowed compared to competitors, the case for Roam has narrowed. The case for Obsidian has only widened.

Here's what actually matters for the decision.

Side-by-side comparison

Where Obsidian wins

Price. Obsidian is free for personal use. Roam is $15/month with no free plan. For the same core functionality (bidirectional links, graph view, daily notes), Obsidian costs nothing. Sync and Publish are paid add-ons, but the note-taking and linking experience is free.

Data ownership. Your notes are plain markdown files on your device. No cloud dependency. No vendor lock-in. If Obsidian disappears, your files remain. Roam is cloud-only. Your data lives on Roam's servers. Export is JSON, which is less portable than markdown.

Offline. Obsidian works fully offline. Roam requires an internet connection for everything. If you work on planes, in libraries, or in areas with unreliable connectivity, this matters.

The plugin ecosystem. 1,600+ community plugins versus Roam's roam/js extensions. Citation management, spaced repetition, kanban boards, calendar integration, AI plugins, custom CSS themes. The breadth is not comparable. Obsidian's plugin ecosystem is the largest in PKM. Roam's extension model is more limited and developer-oriented.

Canvas. Obsidian Canvas provides a spatial thinking surface for arranging notes, images, and cards visually. Roam has no spatial canvas.

Performance. Obsidian handles vaults with 10,000+ notes efficiently. Roam performance with large graphs has been a persistent user complaint.

Long-form writing. Obsidian's markdown editor supports long documents with headings, paragraphs, and embedded content. Roam's outliner forces everything into bullet points. For producing articles, research summaries, or longer documents, Obsidian's editor is more natural.

Community and development. Obsidian's community is significantly larger and more active. Development is steady with regular updates. Roam's community has contracted since 2021, and development pace has slowed noticeably. Multiple reviews note that features promised years ago remain unshipped.

Where Roam wins

Block references. Roam's block reference system is still the most granular in any note-taking tool. Every bullet point is an addressable block you can embed, reference, and query from anywhere in your database. Obsidian has block embedding, but Roam's implementation is deeper and more fluid. If your thinking depends on referencing specific ideas (not just pages), Roam's block model is more powerful.

Native queries. Roam's query language lets you surface blocks by attribute, tag, and relationship without installing plugins. Obsidian's Dataview plugin is more powerful in some respects, but it's a plugin. Roam's queries are built into the product.

Daily notes as default. Open Roam and today's daily note is ready. The journal-first workflow is the core of Roam's design, not an opt-in plugin. This captures thoughts with zero friction.

Multiplayer. Roam supports real-time multiplayer editing on the same graph. Multiple people can write simultaneously. Obsidian has no native collaboration. For couples, research partners, or small teams who want to share a graph, Roam's multiplayer is a specific capability.

The outliner model. If you think in nested bullets and block-level indentation, Roam's outliner is native to how your brain works. Obsidian is a document editor. Roam is a thought structuring tool. Some people find the outliner model more natural for thinking, even if it's worse for writing.

The honest picture in 2026

Roam pioneered networked thought. That matters. The concepts Roam introduced, bidirectional links, daily notes, block references, the graph view, changed an entire category. Obsidian, Logseq, Tana, and others all owe a debt to Roam's original vision.

But in 2026, the landscape has shifted. Obsidian is free, local-first, has a plugin ecosystem 30x larger, handles large vaults better, works offline, and has a community that dwarfs Roam's. Logseq offers a similar outliner experience to Roam for free and open source. Roam's development has slowed. Features that were promised years ago remain unbuilt. At $15/month with no free plan, the value proposition is harder to justify than it was in 2021.

Roam is still the right tool for people who love its specific block reference and query system and use it daily. For everyone else, the alternatives have caught up and, in most dimensions, passed it.

A third approach: connections without the linking

Both Obsidian and Roam assume that the value of a knowledge base comes from manually linking ideas. You create the connection. You tend the graph. You maintain the system. The more you link, the more useful it becomes. The less you link, the more it degrades.

Fabric asks whether AI can do that better.

Fabric is an AI workspace where everything you save is automatically extracted, enriched, and understood by the AI assistant. You don't link blocks or create wiki-style references. You save content, any file type, and the Memory Engine maps relationships automatically. Semantic search finds things by meaning. The AI understands your entire library without you building the graph.

Fabric doesn't have Obsidian's plugin ecosystem or Roam's block reference system. It doesn't have a graph view. It doesn't store files as local markdown. It's a different bet: that automatic understanding across all content types is more valuable than manual linking within text files.

If you're leaving Roam because of the price, the slow development, or the cloud-only lock-in, and you're deciding between Obsidian's free local-first model and something else entirely, Fabric offers a different kind of connected thinking. No maintenance. No linking discipline. AI handles the connections. You save things and ask questions.

How to choose

Use Obsidian if you want the free, local-first, extensible note-taking tool with the largest plugin ecosystem. You want data ownership, offline access, and a canvas for visual thinking. You write long-form notes. You're willing to invest time in setup. You want the biggest community for help. Obsidian is the default choice for most people comparing these two in 2026.

Use Roam if you love the outliner model, block-level referencing, and native queries. You use daily notes as your primary workflow. You want multiplayer collaboration on a shared graph. You've used Roam for years and the system is deeply embedded in how you think. And $15/month for a cloud-only tool with slow development doesn't bother you.

Try Fabric if you want connected thinking without the manual linking. AI that understands your content automatically, search by meaning across all file types, and a workspace that handles more than markdown. Especially relevant if you're leaving Roam and want something fundamentally different, not just a cheaper version of the same paradigm. Generous free plan. See also: best second brain app.

FAQs

Is Roam Research dead?

No. Roam is still actively maintained and has a dedicated user base. But development has slowed significantly since 2021, and the community has contracted. Features promised years ago (API, offline mode, mobile improvements) have been slow to materialise. "Dead" is too strong. "Stagnant relative to competitors" is accurate.

Should I switch from Roam to Obsidian?

If price, data ownership, offline access, or plugin extensibility matter to you, yes. Most Roam users who switch to Obsidian report that the transition is worth it. The main thing you lose is Roam's block reference granularity and the outliner model. If those are central to your workflow, the switch is harder.

Can I import Roam into Obsidian?

Yes. Roam exports to JSON and Markdown. Obsidian can import Markdown files. Community tools exist to convert Roam's JSON export into Obsidian-compatible markdown. The conversion isn't perfect (block references don't translate directly), but the content transfers.

Is Roam worth $15/month in 2026?

For a dedicated daily user who relies on block references, native queries, and the outliner model, possibly. For most people, Obsidian offers comparable core functionality for free, with a vastly larger plugin ecosystem and local data ownership. Logseq offers a similar outliner experience for free and open source.

Which has better mobile apps?

Obsidian. Both have iOS and Android apps, but Obsidian's mobile experience is more developed. Roam's mobile apps are basic.

What if I don't want to maintain a knowledge graph at all?

Neither Obsidian nor Roam solves this. Both require manual linking and ongoing maintenance. Fabric organises your content automatically with AI. The trade-off is that you give up local-first storage and manual control. The gain is that the system works without your discipline.
