Deep Dive: Switching from Roam Research to Obsidian
Trade-offs, installation & data architecture
What you trade away
Obsidian is page-and-file-centric rather than a block-native outliner, so Roam's fluid block references, daily-note capture, and block queries require plugins and workarounds.
How to deploy Obsidian
Official desktop or mobile installer
Where your data lives
Each vault is an ordinary folder of Markdown files plus local attachments and configuration; optional paid Obsidian Sync stores end-to-end-encrypted replicas in Obsidian's service
Why fork Obsidian instead of vibe-coding a Roam Research clone?
Roam Research's solo core is compact: build a local-first networked notes app with fast capture, full-text search, backlinks, tags, and Markdown export. A competent builder can reach a useful personal version in one sitting, while the paid product mainly wins on polish, sync, importers.
