The Lightning-Fast Image CDN for Modern Builders
Host, deliver, and cache images with case-sensitive short slug URLs, strict SSRF safety, 24-hour inactivity session control, and permanent edge performance.
Pure Image Response
Direct slug URLs stream raw image bytes with exact MIME headers and Cache-Control: public, max-age=31536000, immutable.
How CdnXyz9 Delivers Media
Three simple steps from initial ingestion to globally distributed edge caching.
Upload or Fetch URL
Direct file upload, clipboard paste, or SSRF-protected remote fetch with MIME validation.
Case-Sensitive Slug
Indexed in PostgreSQL with COLLATE "C" for guaranteed collision-free, short slug URLs.
Global Edge Streaming
Cloudflare Pages Functions middleware streams assets globally with immutable 1-year browser caching.
Engineered for Performance & Security
Zero compromise on speed, safety, authentication, and architectural isolation.
Case-Sensitive Slugs
PostgreSQL COLLATE "C" database indexing ensures abc123, ABC123, and Abc123 remain 100% distinct and collide-free.
3-Strike Brute-Force Lockout
3 failed password attempts trigger an immediate 15-minute server-side IP lockout with live real-time countdown enforcement.
24-Hour Inactivity Session
Rolling inactivity tracking via cryptographically signed HMAC-SHA256 HttpOnly cookies. Idle for 24 hours automatically logs out.
SSRF-Protected Remote URL
Upload directly from any public image URL. Internal IP ranges, loopbacks, and cloud metadata endpoints are strictly blocked.
Real-Time Slug Availability
Debounced client verification and atomic server-side race condition handling ensure custom slugs are unique and guaranteed.
Cloudflare Edge Delivery
Cloudflare Pages Functions middleware streams files from Supabase Storage with sub-millisecond edge latency and full CORS support.
Immutable Edge Caching
Automatic Cache-Control: immutable and ETag headers guarantee lightning-fast repeat delivery across worldwide edge nodes.
Zero-Secret Client Code
Service role keys, passwords, and sensitive operations are isolated within serverless edge functions, keeping browser code 100% secure.
Universal Image Delivery
Native support for all modern web raster, vector, animated, and lossless file types.
Developer API Integration
Direct image embedding in HTML, Markdown, CSS, and applications:
