I’ve been experimenting with a hosted service where you add just one meta tag like:
<meta property="og:image" content="https://uselinkshot.com/acc_123/tmp_456?url=https://yoursite.com/page" />
When someone shares your page, the OG image is generated dynamically (via browser rendering), cached with stale-while-revalidate, and served quickly. You can set up templates for consistent branding, titles, etc.
This avoids:
Manually designing images for each page
Running your own Puppeteer/Playwright setup
Adding heavy infra for what’s essentially a small but important detail
My questions for HN:
Is this actually a pain point you’ve run into?
Would you trust a third-party service for OG images, or prefer rolling your own?
What would make this useful enough to adopt (API access, cache-busting, more control, pricing)?
I’d love to hear whether this scratches a real itch or is just a “nice-to-have.”
Just drag this to your bookmarks bar:
javascript:(function(){ const url = encodeURIComponent(window.location.href); window.open(`https://chatgpt.com/?q=summarize this page ${url}`, '_blank'); })();
Use it while browsing articles or docs — click once and ChatGPT gives you a summary. Super handy for speeding through content!
