คำตอบใน 30 วินาที
เลือก 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. เลือก Roam Research only if you specifically need native block-level references and real-time multiplayer collaboration. Obsidian ชนะ 8-4 overall, and at $0 vs $165/ปี, the value gap is enormous.

Which do you use?
ใครควรเลือกอะไร?
→ เลือก 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.
→ เลือก Roam Research if:
You are a power user who built extensive เวิร์กโฟลว์ in Roam, need native multiplayer collaboration, or specifically rely on SmartBlocks ระบบอัตโนมัติ that would be hard to replicate in Obsidian.
→ ควรหลีกเลี่ยงทั้งคู่ถ้า:
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.

คำถามที่พบบ่อย
ความเห็นบรรณาธิการ
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.
