Can I use Roam Research or Obsidian offline?
Roam Research requires an internet connection for full functionality since it's cloud-based; offline access is extremely limited. Obsidian works completely offline—all notes are stored locally on your device, and you can access and edit them without any internet connection. This is a major advantage for Obsidian if you need reliable offline access.
Obsidian is significantly cheaper. Roam Research costs $180/year with no option to avoid the subscription. Obsidian is free forever for the core app; you only pay if you want Sync ($10/month = $120/year) for cloud backup or Publish ($10/month) for web publishing. You can use Obsidian indefinitely without spending anything.
Roam Research is built for collaboration with native real-time multi-user editing and shared workspaces. Obsidian lacks built-in collaboration; you'd need to use third-party tools like Git, Google Drive, or manual file syncing. If team collaboration is essential, Roam Research is the clear choice.
Can I export my data if I stop using either app?
Both allow data export, but Obsidian has a major advantage. Obsidian stores notes as plain Markdown files on your device, so you own your data outright and can use them anywhere. Roam exports to Markdown but your primary data is in their cloud; exporting is a one-time process. Obsidian's format is more future-proof.
Obsidian offers native iOS and Android apps with full feature parity to the desktop version, allowing you to write and edit notes anywhere. Roam has only a web-based mobile interface that's limited and less functional. If mobile note-taking is important, Obsidian is significantly better.
