Peekalink

Peekalink generates rich link previews from a URL (or file types like PDFs and documents) so your app can show titles, images, and metadata instead of empty cards. It’s for developers building feeds, share flows, chat messages, or any place where link cards need to render correctly across different sites.

• Multi-format support Handle websites, social posts, product links, PDFs, presentations, images, audio, video, and more
• AI fallbacks Use fallback preview logic when a site doesn’t expose the metadata you need
• Redirect and dynamic handling Follow redirects and deal with dynamic content and platform requirements
• Smart caching and optimized media Reduce repeat work and return preview assets efficiently
• Proxying, custom headers, and HTTPS upgrades Improve fetch consistency when targets block or require specific request behavior
• Monitoring for reliability 24/7 monitoring with claims of 99.9% uptime

If you don’t want to maintain your own scraper, renderer, and failure handling, Peekalink focuses on “preview the link reliably” as the core service. It can return results in a structured JSON format, which makes it easy to plug into backends.

The included capabilities also line up with real-world preview problems, like inconsistent metadata across platforms, redirects, and missing Open Graph/Twitter card fields, where a fallback approach matters.
