SupabaseRecommendedSite citedpositive
“### 1. Supabase Storage — best for database-driven permissions”
+ database-driven permissions via PostgreSQL Row Level Security

“Supabase is particularly interesting because its storage permissions integrate directly with PostgreSQL Row Level Security (RLS).”

+ built-in image optimization

“- On-demand image resizing. - Automatic WebP optimization.”

+ ease of use

“| Yes | Excellent (Postgres RLS) | Built in | Very easy”

+ centralized authorization logic

“Most importantly, you can keep your authorization logic in one place.”

FirebaseRecommendedSite citedmixed
“### 2. Firebase Storage — best for authentication-based access rules”
+ authentication-based security rules

“Firebase uses a dedicated Security Rules system.”

+ integration with Firebase Authentication and Firestore

“Firebase is especially attractive if you're already using Firebase Authentication and Firestore.”

− path-based rules harder to maintain for complex permissions

“Downside: Its rules are primarily path-based. Complex application-specific permissions can become harder to maintain, and image transformations generally require additional services.”

− image transformations require additional services

“Downside: Its rules are primarily path-based. Complex application-specific permissions can become harder to maintain, and image transformations generally require additional services.”

AppwriteRecommendedSite citedpositive
“### 3. Appwrite Storage — best for straightforward per-file permissions”
+ explicit per-file permissions

“Appwrite's explicit file-level permission system is worth considering.”

+ straightforward permission model

“Appwrite has one of the most straightforward permission models.”

+ image transformations and previews

“Appwrite also offers: - Image transformations. - File previews.”

+ ease of use

“| Yes | Excellent (file-level permissions) | Built in | Very easy”

AWS S3Recommendedmixed
“### 4. AWS S3 — best for maximum scalability and flexibility”
+ scalability and flexibility

“### 4. AWS S3 — best for maximum scalability and flexibility”

+ multipart uploads and durability

“- Multipart uploads for large files. - High durability.”

+ presigned URLs

“- Presigned upload and download URLs.”

− requires more infrastructure and application code

“Downside: More infrastructure, configuration, and application code to maintain.”

− not a complete application backend

“However, S3 is fundamentally infrastructure rather than a complete application backend.”

Cloudflare R2Recommendedmixed
“### 5. Cloudflare R2 — best for cost-conscious object storage”
+ no egress charges

“- No traditional R2 egress charges for data transferred out of R2.”

+ S3-compatible APIs

“- S3-compatible APIs.”

+ cost control

“It's a particularly attractive storage backend when you want to keep infrastructure costs under control.”

− no per-file authorization system

“However, R2 doesn't provide a Supabase-style per-file authorization system.”

CloudinaryRecommendedSite citedmixed
“### 6. Cloudinary — best for image-heavy applications”
+ image and video processing

“- Image resizing. - Automatic format conversion. - Image compression. - Video processing.”

+ asset-level access controls

“It also supports asset-level access controls.”

+ authenticated delivery protects originals and derived versions

“Its authenticated delivery type protects both originals and derived versions.”

− less suitable as sole storage and authorization system

“Downside: It is less suitable as your only storage and authorization system for general application documents and files.”
