Key Differences
Preview accuracy and platform coverage. PreviewOG renders previews for a wider range of platforms, including messaging apps like Discord, Slack, and WhatsApp. opengraph.xyz focuses on the four major social networks. If your audience shares links primarily on Facebook and Twitter/X, both tools will serve you well. If you also need to know how links look in Slack threads or Discord channels, PreviewOG covers those cases.
Editing workflow. PreviewOG lets you modify OG tag values directly in the interface and see the preview update in real time. This is useful when you are drafting titles and descriptions and want to test different lengths before committing changes to your site. opengraph.xyz shows you the current state of your tags but does not offer an editing sandbox — you need to update your HTML, deploy, and re-fetch.
Validation depth. PreviewOG flags specific issues like missing og:image dimensions, descriptions that exceed platform character limits, and images with incorrect aspect ratios. opengraph.xyz displays the raw tag values it found, which is helpful for a quick check but leaves the interpretation to you.
Pricing and simplicity. opengraph.xyz is entirely free with no account required. You paste a URL, hit enter, and see results. That simplicity is a genuine strength — there is no friction. PreviewOG also offers a free tier, but its more advanced features (API access, bulk checking) are available on paid plans.
Image handling. A common pain point with OG tags is getting image dimensions and aspect ratios right. Different platforms crop images differently — Facebook prefers 1.91:1, Twitter/X supports both square and landscape, and LinkedIn has its own display logic. PreviewOG shows you how each platform will crop your specific image, making it easier to spot problems before sharing. opengraph.xyz shows the image as-is without platform-specific cropping simulation.
Team and workflow fit. If you are a solo blogger checking a link before posting, opengraph.xyz's zero-friction approach is hard to beat. If you are part of a content team that publishes daily across multiple channels, PreviewOG's bulk checking and API integration make repeated validation practical rather than tedious. The choice often comes down to how frequently you need the tool.
When to Choose PreviewOG
You manage multiple sites or pages and need to check OG tags in bulk.
Your audience shares links on messaging platforms (Discord, Slack, WhatsApp) in addition to social media.
You want to experiment with different titles and descriptions before deploying changes.
You need API access to integrate OG validation into a CI/CD pipeline or content management workflow.
You want explicit validation warnings rather than raw tag output.
When to Choose opengraph.xyz
You need a quick, no-account, completely free check of a single URL.
Your sharing channels are limited to Facebook, Twitter/X, LinkedIn, and Pinterest.
You prefer a minimal interface with zero setup.
You are checking OG tags occasionally rather than as part of a regular publishing workflow.
FAQ
Yes. opengraph.xyz is fully free with no paid plans, no account registration, and no usage limits. You paste a URL and get results immediately.
Both tools fetch your actual OG tags, so the underlying data is the same. The difference is in rendering. PreviewOG replicates the visual layout of each platform more closely, including platform-specific text truncation and image cropping behavior. opengraph.xyz provides a good general approximation but may not reflect exactly how each platform handles edge cases like long titles or non-standard image sizes.
Absolutely. A practical workflow is to use PreviewOG during content creation (to draft and refine your tags with real-time editing) and opengraph.xyz for a quick sanity check after deployment. The tools complement each other well.
