ShotOG — OG Image Generation API built with Hono on Cloudflare Workers

[2214962083]

Hey Hono community! 👋

I built ShotOG, an OG image generation API using Hono on Cloudflare Workers. Thought I'd share it here since Hono made the routing and middleware layer incredibly clean.

What it does

Generate Open Graph images via URL — no headless browser, no Puppeteer. Just edge-native rendering using Satori + resvg-wasm.

Try it now (just open this URL):

Why Hono?

• Clean routing for API endpoints (/v1/og, /v1/keys, /v1/keys/usage)
• Middleware composition (auth, caching, error handling)
• First-class Cloudflare Workers support
• Lightweight — entire bundle is 1568 KB gzipped

Features

• 8 production-ready templates (blog, product, social, event, etc.)
• ~50ms generation time at the edge
• D1 database for API key management + usage tracking
• Cache API integration
• TypeScript SDK
