Is Obsidian worth the price?

Great value

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.

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

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
