Obsidian, a powerful note-taking tool, is loved by knowledge workers. However, its official synchronization service is pricey, with a minimum annual fee of $48. For budget-conscious users, this can be a significant expense. Fortunately, there's a more affordable alternative: combining Cloudflare's R2 storage service with Obsidian's Remotely Save plugin. R2 is a compliant S3 object storage service with enough free tier for personal use. R2 offers 10GB of storage, plus 100 million requests of A-class and B-class operations, with completely free data egress. This means that for most Obsidian users, syncing notes may not require any additional costs at all.
