- performance
- compatibility lag with major framework updates (Next.js 16 Turbopack, Tailwind V4)
- idempotency issues with duplicate file IDs after deletion preventing re-upload with same custom ID
- limited file management API (e.g., no bulk delete, conditional removal, or selective image replacement)
When to Use
Best when:- Next.js applications
- rapid prototyping with file uploads
- serverless deployments
- React-based projects
- need strict data residency compliance
- require on-premises deployment
- working with cutting-edge framework versions before they stabilize
- need granular file lifecycle management
