What the video shows
Pick a scene to jump to it. Each one links to the part of this page it comes from.
Screens are the real app on seeded demo data. The scanner result is a real public page. Public launch 15 October 2026.
Context
What it does
Shareglow generates Open Graph images from templates, scans any URL for broken or missing preview tags, and serves short links that carry their own preview image. Every problem the scanner finds comes with the code to fix it for the site’s framework: Next.js, Nuxt, Astro, WordPress or Shopify.
The direct competitor is OpenGraph.xyz. Shareglow charges the same price and gives three to five times the limits on every paid plan.
Why it is different
- A real Free plan. No card: 100 OG images and 10 short links a month, with unlimited scans and previews.
- Monitor and fix. It watches a site’s pages and alerts when a preview breaks. One button pushes the fix everywhere: it asks Facebook to re-scrape, versions the image URL, and shrinks the image under 300 KB for WhatsApp.
- Previews where people actually share. It simulates 30+ platforms worldwide, including WhatsApp, Telegram, WeChat, LINE, Zalo and KakaoTalk. A small snippet serves real meta tags to crawlers on single-page apps.
A REST API and an MCP server are part of the product, not the pitch.
Who it is for
Indie developers and founders, content marketers, agencies, and sites with many pages — listings, e-commerce stores and blogs.
Pricing

How it is built
A pnpm and Turborepo monorepo. The web app is Next.js 16 on Cloudflare Workers through
@opennextjs/cloudflare. Images render with Takumi in WebAssembly, never a headless Chrome, and
are cached in R2 behind signed URLs. Redirects run on KV, jobs on Queues, click analytics on
Analytics Engine. Data lives in Neon Postgres through Drizzle, sign-in uses Better Auth, and pages
that need a real browser go to a Playwright worker on an Oracle A1 server.
Where it stands
