Is Obsidian worth the price?
Obsidian core app is genuinely free with no feature gating, every note-taking and knowledge management feature works without paying.
The optional paid services (Sync at $4-5/month, Publish at $8-10/month) are the only revenue sources. This makes Obsidian one of the most honest pricing models in productivity software: you own your data (plain Markdown files stored locally), and you pay only for convenience services.
A user with Sync + Publish pays $12-15/month, comparable to Notion Plus ($10/month) but with full data ownership. The Catalyst license ($25 one-time) and Commercial license ($50/user/year) exist primarily as support mechanisms, not feature unlocks.
Hidden Costs & Gotchas
Sync ($4-5/month) is almost mandatory for multi-device users. While you can use free alternatives (iCloud, Google Drive, Git), they introduce sync conflicts that Obsidian Sync solves with end-to-end encryption and proper conflict resolution. Most serious users end up paying for Sync
Publish ($8-10/month per site) has no free tier, if you want to publish notes to the web through Obsidian, you pay. Alternatives like Quartz (free, open-source) can publish Obsidian vaults but require technical setup
Community plugins are free but community-maintained with no guaranteed support or security auditing. Some plugins stop working after Obsidian updates, and there is no official plugin marketplace with verified publishers
The Commercial license ($50/user/year) is required for companies with 2+ employees using Obsidian for work. Many small teams overlook this requirement. It unlocks no additional features, it is purely a licensing compliance cost
No built-in collaboration beyond Sync shared vaults. Real-time multiplayer editing requires third-party solutions. Teams needing Google Docs-style collaboration will find Obsidian inadequate without significant workarounds
Mobile app (iOS/Android) is free but less capable than desktop. Complex plugins often do not work on mobile, and the editing experience is more limited
Educational discount (40% off Sync and Publish) requires verification for students, faculty, and nonprofit employees. The discount is generous but not automatically applied
How Obsidian Compares to Competitors
Notion Plus ($10/user/month billed annually, $12/month monthly) is the most common alternative. Notion includes sync, collaboration, web publishing, databases, and AI features in one subscription, no separate add-on purchases. For teams, Notion is simpler to adopt and cheaper per-user when you need sync + publish ($10/month vs Obsidian $12/month for Sync + commercial license). Obsidian advantage: local-first data ownership, Markdown files, offline-first, no vendor lock-in. Notion stores everything on its servers.
Logseq (free, open-source) is the closest philosophical alternative, local-first, Markdown-based, with bidirectional linking. Logseq Sync costs approximately $5-6/month (EUR 5), comparable to Obsidian Sync. Logseq advantage: outliner-first interface, open-source core. Obsidian advantage: larger plugin ecosystem (1,500+ plugins vs ~200), more mature editor, and dedicated Publish service. Roam Research ($15/month or $165/year) pioneered bidirectional linking but costs 3x more than Obsidian Sync and stores data in the cloud. Roam Believer plan ($500 for 5 years, ~$8.33/month) is competitive long-term but requires a large upfront commitment. For most users, Obsidian offers better value and data ownership than Roam.
How Obsidian's pricing compares
At $4/mo, Obsidian is mid-range of its 6 direct competitors ($3.22 to $14.99/mo across the set).
