Five free checkers, one job: making your links look right when shared. Here is what each is genuinely best at — including where the others beat us.
Best at: The full checkup: 8-platform previews, 0–100 tag audit with fixes, checker-to-generator fix loop, meta tag + sitemap tools, free API and score badge.
Watch out: No multi-language yet, no MCP server yet.
Run a free check →Best at: The biggest OG brand — tool matrix, WordPress plugin, AI templates and CDN-hosted automation for large sites.
Watch out: Generation features sit behind a paid SaaS; the free checker has no per-tag audit.
Full comparison →Best at: A superbly structured single-page checker with a free API, an MCP server and Spanish/Portuguese versions.
Watch out: Five platforms, no generator, no sister tools.
Full comparison →Best at: A clean single-page checker with template and inspiration galleries, strong in the US.
Watch out: Five platforms, no audit score, templates are a gallery rather than an editor.
Full comparison →Best at: A quick check on a high-authority QR/barcode platform — handy if you already use Orca Scan.
Watch out: A side feature: five platforms, no audit, no generator.
Full comparison →Pick by the job you are doing right now. Just want to see a preview once? Any of these loads in seconds. Auditing a page before launch? You want per-tag verdicts, not just a render. Fixing a broken image? You want the generator one click from the audit. Running a large WordPress site that needs automated generation? That is a paid SaaS job, and OpenGraph.xyz does it well.
We built this site because the check and the fix kept living in different places. Every tool here — the 8-platform checker, the generator, the Meta Tag Checker, the Sitemap Validator, the API and the score badge — is free, needs no signup, and connects to the next step in the flow.
For a quick preview, any of the tools above works. For a full checkup — eight platform previews, a 0–100 audit score with per-tag fixes, a generator pre-filled from your results, and meta tag + sitemap tools alongside — this site was built exactly for that job.
All five checkers are free to use. The difference is what sits behind the free tier: some gate generation or automation behind paid plans; everything on ogimagechecker.com — checker, generator, meta tag auditor, sitemap validator, API — works without an account.
OpenGraph.xyz offers a WordPress plugin for automated OG image generation at scale. For checking and fixing tags on individual pages — including full head audits and sitemap validation — use the free tools here and paste the results into whatever SEO plugin you run.
