Renderfy
Best API for OG images from any stack
Send a single POST request with Tailwind-styled HTML and get a 1200×630 PNG back in the response body. Works from any backend — no framework lock-in. Built-in OG-image dimension preset, custom Google Fonts by family name, saved templates with {{ placeholder }} substitution for dynamic content, and batch rendering for generating multiple cards in one call.
Pros
- ✓ Framework-agnostic — works from any backend, not just Next.js
- ✓ Built-in 1200×630 OG-image dimension preset
- ✓ Full Tailwind CSS support in templates
- ✓ Saved server-side templates with placeholder substitution
- ✓ Custom brand fonts by Google Font family name
- ✓ Batch rendering (up to 20 OG images per call)
- ✓ Binary response — no hosted URL to fetch separately
- ✓ EU data residency
Cons
- ✗ Managed API — requires an API key and network call
- ✗ Satori-based image path has some CSS limitations (no gap-*, no shade 950)
Pricing: 100 free credits on signup (no card). OG images cost 1 credit each. Paid plans from $9/mo.
Vercel OG (@vercel/og)
Best if you're already on Next.js + Vercel
Built into Next.js via the next/og package. Uses Satori under the hood (same engine as Renderfy's image path). Runs at the edge as a Vercel serverless function — zero additional cost if you're on Vercel. Limited to JSX/React syntax and the Vercel platform.
Pros
- ✓ Zero config for Next.js projects on Vercel
- ✓ Runs at the edge — fast response times globally
- ✓ Free (included with Vercel hosting)
- ✓ Uses Satori — same rendering quality as Renderfy's image path
Cons
- ✗ Locked to Next.js and Vercel — can't use from Django, Rails, Go, etc.
- ✗ Same Satori CSS limitations (no gap-*, limited font format support)
- ✗ No saved templates, batch rendering, or idempotency
- ✗ Must write JSX, not plain HTML or Tailwind strings
- ✗ No PDF output
Pricing: Free (included with Vercel hosting).
Cloudinary
Best if you already use Cloudinary for image management
URL-based image transformations that can overlay text and images onto a base template. Not a true HTML renderer — OG images are composed by chaining URL parameters, not writing markup. Powerful but complex syntax for anything beyond simple text-on-background.
Pros
- ✓ URL-based — no API call needed, just construct a URL
- ✓ Massive CDN with global edge caching
- ✓ Rich image manipulation beyond OG (crop, resize, filters)
- ✓ Free tier available
Cons
- ✗ Not HTML rendering — URL parameter chains for layout
- ✗ Complex syntax for anything beyond text overlays
- ✗ No Tailwind, Markdown, or code input
- ✗ No true template substitution for dynamic content
Pricing: Free tier (25 monthly transformations). Paid plans from $89/mo.
Placid
Best for no-code workflows with broad integrations
Template-based image and video generation with the widest integration ecosystem — Zapier, Make, Airtable, ChatGPT, Ghost, n8n, Webflow, WordPress. Austria-based, GDPR compliant.
Pros
- ✓ Widest integration ecosystem among OG image tools
- ✓ GDPR compliant (Austria-based)
- ✓ Video output alongside images and PDF
- ✓ Mobile SDK available
Cons
- ✗ Templates are GUI-only — no code-first workflow
- ✗ Starts at $19/mo for only 500 credits
- ✗ No raw HTML or Tailwind input
Pricing: Free trial. Paid from $19/mo (500 credits) to $249/mo (100,000 credits).
Frequently asked questions
What is an Open Graph image?
An Open Graph (OG) image is the preview image that appears when you share a link on Twitter, Slack, LinkedIn, Discord, or iMessage. It's specified via the og:image meta tag in your page's HTML head. The standard size is 1200×630 pixels.
Why generate OG images dynamically?
Static OG images can't include page-specific content like a blog post title, author name, or publish date. Dynamic generation lets you create unique, branded share cards for every page automatically — improving click-through rates from social media and messaging apps.
Can I generate OG images without Next.js?
Yes. Vercel OG requires Next.js, but API-based tools like Renderfy work from any backend — Node.js, Python, Go, Ruby, PHP, or even a curl command. You send HTML or Tailwind markup and get a PNG back.
How much does OG image generation cost?
Vercel OG is free if you're on Vercel. Renderfy gives 100 free credits and charges 1 credit per image ($9/mo for 5,000). Cloudinary starts at $89/mo. Bannerbear starts at $49/mo.
