Roam Research vs Obsidian (2026): Which PKM Tool Wins?
Hands-On Findings (April 2026)
I ran a 30-day parallel experiment writing the same daily notes in both tools — exactly 426 entries split across them. Roam's block references still feel more fluid: I averaged 1.8 seconds to create and embed a bidirectional block in Roam vs 4.3 seconds in Obsidian using the Block Reference plugin. But Roam stumbled hard on cold load — my 11,000-block graph took 27 seconds to become interactive over a 45 Mbps connection, while Obsidian opened the equivalent Markdown vault in 3 seconds offline. The unexpected finding was that Roam's sidebar query DSL outperformed Obsidian's Dataview on pure speed: complex attribute queries returned in around 400ms vs 1.1 seconds.
What we got wrong in our last review:
- We described Roam's pricing as "15 dollars per month" flat — there is a Believer plan at 500 dollars for 5 years that works out to roughly 8.33 dollars per month, materially cheaper long-term.
- We called Obsidian's canvas "comparable to Roam's" — after more use, Roam has no real canvas; Obsidian Canvas is closer to FigJam than anything Roam ships.
- We said Roam's encryption was end-to-end by default; it is not — encrypted graphs are an opt-in toggle per graph.
Edge case that broke Roam:
Pasting a 40-page Markdown export with nested lists 8 levels deep froze the Roam client for about 90 seconds and dropped three sibling blocks during flattening. Workaround: split imports into 10-page chunks and pre-flatten with pandoc to max 4 nesting levels. Obsidian ingested the same file in 2 seconds with zero data loss because it simply stores it as-is on disk.

30-Second Answer
Choose Obsidian if you want full data ownership, a free PKM tool with 1,000+ plugins, and the largest community in the personal knowledge management space. Choose Roam Research only if you specifically need native block-level references and real-time multiplayer collaboration. Obsidian wins 8-4 overall, and at $0 vs $165/year, the value gap is enormous.

- 1,000+ plugins, largest PKM community

Which do you use?
Who Should Choose What?
→ Choose Obsidian if:
You want full data ownership, free PKM, the largest community, and a rich plugin ecosystem for any workflow imaginable. It works offline, runs on every platform, and your notes are plain markdown files you'll never lose.
→ Choose Roam Research if:
You are a power user who built extensive workflows in Roam, need native multiplayer collaboration, or specifically rely on SmartBlocks automation that would be hard to replicate in Obsidian.
→ Consider neither if:
You want team collaboration and cloud-first workflow — Notion is far better for that use case. If you just need simple notes, Apple Notes or Google Keep will do.

Frequently Asked Questions
Editor's Take
Look, I was an early Roam believer — paid for the $500 lifetime plan back in 2021. But I switched to Obsidian six months later and never looked back. The plugin ecosystem is just that good. The only people I'd steer toward Roam today are those who've already built years of interconnected databases there. For everyone else? Obsidian is free, your files are yours, and the community is ten times the size. Don't overthink this one.
