# Shareglint as analternative to @vercel/og

A free library that turns JSX into an image inside your own Next.js or edge function.

## Before you read on

If you are on Next.js or Vercel and happy writing the card in JSX, @vercel/og is free, fast and runs right next to your pages — use it. We make sense when the layout needs CSS it does not support, when the text is not Latin, or when your site is not JavaScript at all.

## The differences, plainly

| What | @vercel/og | Shareglint |
|---|---|---|
| Price | Free library, your compute | From free, then $9 for 2,000 |
| Template language | JSX (React) | Plain HTML and CSS |
| CSS support | A subset — flexbox; grid is still arriving | Everything Chrome renders |
| Where it runs | Next.js and edge runtimes, 500 KB bundle limit | Any stack, one HTTP request |
| Fonts | You bundle and load them | Pick from our list |
| Thai, Arabic, CJK text | Known layout problems | Rendered by a real browser |

@vercel/og pricing (free, you pay for the function that runs it) comes from their own public page, checked 2026-10. If something has changed — tell us and we will fix it.

## Which one to pick

- **Take @vercel/og:** You are on Next.js, your design fits in flexbox, and you would rather not depend on another service.
- **Take Shareglint:** You are on Rails, Django, WordPress, Hugo or Ghost, your design already exists as HTML and CSS, or Satori keeps breaking your layout.
