xmoj — Image CDN & Screenshot API

Internal Cloudflare-edge image transform CDN + website screenshot API for the portfolio

launched infra

Drop-in replacement for wsrv.nl (image transform) and thum.io (screenshots). Single CF Worker on the xmoj.com zone with Photon WASM (Rust→WebAssembly) for resize/crop/WebP conversion and CF Browser Rendering (headless Chromium at the edge) for website screenshots. Ships with lazy-load placeholders, per-IP rate limit, SSRF deny-list (private IPs, cloud metadata, IPv4-mapped IPv6), live stats, generated ToS/Privacy via arulez.com, and a native-app docs UI. Backbone of the portfolio: every other project routes images through xmoj.com for resize+WebP delivery, saving 80-95% per image.

Local Fit

Bedrock infra: 10/10 capital efficiency. Replaces ~$60/mo wsrv.nl + thum.io retail across 30+ portfolio sites for $0 marginal cost (shared $5/mo Workers Paid). Strong moat (8): SSRF hardening + per-IP rate limit + lazy-load + arulez legal integration would take a competitor weeks to replicate at this code quality. ETag conditional GET + cost-savings dashboard now live. AVIF deferred (encoder too heavy). 11 of 14 roadmap items completed in 1 day — execution velocity 10/10.

Value basis: Internal use only — replaces $5+/mo wsrv.nl premium tier and $0.50/1k thum.io for the entire portfolio. Value is the avoided 3rd-party CDN cost amortized over 30+ portfolio projects.

📐 GAP TO LEADER

Bedrock infra. Not optimizing for growth — optimizing for reliability and cost-share across the portfolio.

SWOT Analysis

💪 Strengths

•100% CF native (Photon WASM + Browser Rendering, no third-party dep)
•Lazy-load placeholder for screenshots — never blocks user
•SSRF deny-list covering RFC1918, IPv4-mapped IPv6, cloud metadata, encoded IP forms
•Per-IP rate limit immune to Referer spoofing
•Single shared Worker = zero marginal cost across 30+ sites

⚠️ Weaknesses

•Niche internal use; not directly monetizable
•Photon WASM cold-start adds ~50ms vs hot CF Image Resizing
•Browser Rendering is a paid CF feature (per-second billing)
•No AVIF support yet (3.5MB encoder too heavy for now)

🎯 Opportunities

•Could open as paid public CDN if ever needed (drop-in for wsrv.nl users)
•AVIF support could land if CF reduces WASM size or offers native AVIF encoder
•WAF + bot signature add-ons could become a Cloudflare-marketplace product

🚨 Threats

•Cloudflare could ship native Image Transformations on free zones, removing need
•wsrv.nl could open Indonesia POP, removing latency advantage
•Browser Rendering pricing changes could break /shot economics

How to Raise the Score
