Scan any URL, fix broken Open Graph tags with copy-paste code, preview your link on 30 platforms, and generate on-brand share images. Free plan, no card. Paid plans start at $29 a month.
Hi Product Hunt, I'm Brandon, the maker of Shareglow. I'm a solo developer based in Vietnam.
Every link you share is a small ad. When the preview is broken, the image is missing, cropped, or stale, people scroll past it. And you usually find out from a customer, not from a tool.
Shareglow does four things:
- Scan: paste a URL, see every Open Graph and Twitter tag graded as error, warning or pass, with code to fix each one for Next.js, Nuxt, Astro and WordPress. - Preview: one URL rendered as 30 platform cards (Facebook, LinkedIn, X, WhatsApp, Telegram, Slack, Discord, Zalo, WeChat and more), so you see it before you post. - Monitor: point it at your sitemap and get an alert when an image 404s or a tag goes missing. - Generate: on-brand 1200x630 images from templates, in any script (Latin with Vietnamese, CJK, Thai, Arabic, Hebrew, Devanagari, Cyrillic), plus short links with their own preview and A/B tests that pick a winner.
It is also reachable from code: a REST API, an MCP server (7 tools) for agents like Claude Code, and a GitHub Action that fails a build when OG tags are missing.
Pricing is simple: there is a Free plan with no card. Paid plans are $29 / $59 / $199 a month (5,000 images on the $29 plan, 25,000 on $59, 150,000 on $199).
Launch offer: the first 100 customers on a yearly plan get 40% off for as long as their yearly subscription stays active. The counter is enforced in the database, so the cap is real.
I would love feedback on two things: which platform previews matter most to you, and what the scanner misses on your site. I'll be here all day.

Who hunted Shareglow?
Shareglow was hunted by Brandon Ta. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
