Local-first / data ownershipObsidian gives you full markdown files in folders you own. Logseq similarly stores everything locally as markdown or org-mode files. Notion, Coda, and Capacities are cloud-hosted with proprietary export formats.

Open sourceLogseq is genuinely open source under AGPL-3.0. Obsidian's core is proprietary but its plugin API is MIT and the community has built thousands of extensions. Notion, Coda, and Capacities are closed source.

Cheapest paid tierObsidian's $4/mo Sync is the cheapest paid option — and it's optional. Logseq Sync at $5/mo is similar. Notion, Coda, and Capacities all sit around $10/seat or $10/Doc Maker.

CollaborationNotion has the most mature real-time collaboration. Coda is close — its Doc Maker model lets editors collaborate live. Obsidian, Logseq, and Capacities are primarily single-user tools with collaboration as a secondary feature.

Formulas / database powerCoda's formula language is the deepest — full programming-language power against your tables. Notion's relational databases are solid for indie use. Obsidian's Dataview plugin and Logseq's queries give markdown-shape data a SQL-ish surface but require plugins or setup.

Linking / graph viewLogseq is built around the networked-thought paradigm — bidirectional links, journal-first, block references. Obsidian and Capacities both have strong graph views. Notion has backlinks but no graph; Coda is doc-focused with weak inter-doc linking.

Best for shapeEach fits a different shape. Notion for teams, Obsidian for solo PKM, Coda for business automation, Logseq for research/networked thought, Capacities for object-focused thinkers.
