What is FSNotes?
FSNotes is an open-source note manager for macOS and iOS. The app stores notes as Markdown files in the file system, with no proprietary format and no mandatory cloud service. Users who prefer their data as readable text files on their own hard drive rather than in an opaque database will find it fits that need well. A one-time purchase through the App Store is required; there are no subscription fees.
Core features
- Markdown with syntax highlighting: Code blocks are color-highlighted for more than 30 programming languages, directly while writing.
- AES-256 encryption: Individual notes can be encrypted, for example for credentials or sensitive project information.
- Git integration: A Git repository can optionally be connected as a backend, enabling automatic versioning and backups without additional tools.
- TextBundle support: The open TextBundle format allows lossless migration to other Markdown editors.
- iCloud sync: Notes sync between Mac and iPhone via iCloud. Other sync services such as Dropbox or WebDAV are not supported.
- Performance with large libraries: The app handles more than 10,000 files without noticeable slowdown.
Who is FSNotes for?
Developers who manage documentation, code snippets and project notes in Markdown and want to avoid vendor lock-in. The keyboard-centric interface suits workflows where reaching for the mouse is kept to a minimum. That said, users who depend on multiple sync services or need nested folder structures on iPhone will hit limits quickly. The iOS version does not support subfolders, which becomes a structural problem in larger, more established note systems.
Context & alternatives
FSNotes belongs to the category of file-system-based note apps that treat Markdown as a native format rather than an export option. Comparable tools in this space include Obsidian and iA Writer. Obsidian offers a considerably more extensive plugin architecture and runs cross-platform. For those who do not need a plugin ecosystem but want a lightweight, transparent tool with open source code, FSNotes is the more direct option.
