OneDrive works if you live inside Microsoft 365. The moment you need a real API, true encryption, or reliable cross-platform sync — you need a better option.
OneDrive is designed to keep you inside Microsoft 365. Pricing, features, and storage quotas are deliberately tied to your M365 subscription tier.
OneDrive has a documented history of sync conflicts, phantom duplicates, and files that appear synced but were quietly skipped.
OneDrive offers no S3-compatible API and limited WebDAV support, making it a dead end for developers, server admins, and automation workflows.
Like most major providers, Microsoft holds the encryption keys to your data. Their compliance with government requests can expose your files.
Cross-platform. S3 and WebDAV APIs. AES-256 encryption. No per-seat fees. No ecosystem lock-in.
