Notion asks EUR 9.5 per month for its entry-level team plan, while Obsidian charges just $4 per user per month for basic sync. That gap is the single most important number in this comparison, because it defines the two fundamentally different approaches to knowledge management: a structured, all-in-one workspace versus a lightweight, modular note-taking system. The choice between them is less about features and more about how much you are willing to pay for the convenience of a pre-built ecosystem.
Notion’s pricing page is currently region-priced in euros, which adds a layer of currency consideration for international users. The Free tier is EUR 0/month, designed for individuals organizing personal projects. The Plus plan, at EUR 9.5/month, is aimed at small teams and professionals who need to collaborate. For growing businesses, the Business tier costs EUR 19.5/month, offering streamlined teamwork features. There is also a separate line item for Custom Agents at $10/month, which functions as an add-on rather than a core subscription tier. The structure is linear: as your team grows and your need for collaboration deepens, the cost steps up predictably.
Obsidian, by contrast, treats its core application as free and sells specific capabilities as add-ons. The Sync service, which provides end-to-end encryption, cross-device syncing, and version history, costs $4/month per user. If you want to share your notes publicly, the Publish feature is $8/month, requiring no technical knowledge and allowing for customizable themes. There is also a one-time Catalyst contribution of $25, which grants early access to beta versions, community badges, and exclusive channels. For organizations, there is a Commercial tier at $50/year per user, which supports development and offers featured organization status. This modular approach means you only pay for what you actually use, but it also means that a fully equipped Obsidian setup can accumulate costs if you subscribe to multiple add-ons.
Logseq’s pricing status is unconfirmed. No official pricing URL was found, and the vendor has not published a clear cost structure. Because of this lack of transparency, it is impossible to include Logseq in a direct price comparison. Users interested in Logseq must rely on community discussions or direct inquiry, making it a risky option for businesses that need predictable budgeting.
| Vendor | Free Tier | Entry Paid Tier | Notable Add-ons |
|---|---|---|---|
| Notion | EUR 0/month | EUR 9.5/month (Plus) | Custom Agents: $10/month |
| Obsidian | Core app free | $4/month per user (Sync) | Publish: $8/month, Catalyst: $25 |
| Logseq | Unconfirmed | Unconfirmed | None listed |
The decision ultimately comes down to your workflow. If you need a robust, visual workspace with databases and strong collaboration features for a team, Notion’s structure is worth the EUR 9.5/month entry price, even if the Business tier at EUR 19.5/month becomes necessary later. If you prefer a local-first, markdown-based system where you control your data and pay only for specific utilities like sync or publishing, Obsidian’s model is more flexible and often cheaper for individual users. For those who prioritize open-source principles and are willing to navigate an unconfirmed pricing landscape, Logseq remains an option, but the lack of published figures makes it difficult to recommend for professional use where cost certainty is essential.
