Pricing Details
The Obsidian app is based on a flexible model that combines a fully free version with optional paid add-ons. Users can use the app without any restrictions and without needing to register or subscribe, with all notes stored locally on their device. In contrast, the app offers additional paid services such as Obsidian Sync for syncing notes across devices at a cost starting from around $4 to $5 per month depending on the billing method, as well as Obsidian Publish, which allows notes to be published on the web at a cost of approximately $8 to $10 per month. There are also optional support licenses such as Catalyst (a one-time payment) and an annual Commercial license to support app development for enterprise use. Overall, Obsidian remains completely free at its core, while these paid services are optional add-ons to enhance synchronization, publishing, and support without affecting the core user experience.
