What the checker does
LinkGlimpse fetches a public URL on demand, extracts its Open Graph, Twitter Card, canonical, robots, redirect, and image signals, then turns those inputs into representative social previews and concrete repair guidance.
Free, open source, no signup
About LinkGlimpse
LinkGlimpse is a free, open-source link preview and metadata diagnostic tool that shows how a URL may appear across social platforms and explains how to fix missing or incorrect metadata.
What it does not claim
The previews are modeled from live metadata. Social platforms control their own crawlers, caches, crops, fallbacks, and final rendering, so no third-party checker can promise a pixel-perfect platform result or clear a platform cache.
Ownership, maintenance, and pricing
Maintained openly
LinkGlimpse is maintained by Ivan Homola through Tetriz.io.
Open-source license
The public repository uses the GNU Affero General Public License v3.0 or later.
Free core workflow
The hosted single-URL checker is free and does not require an account. Public endpoints may use protective rate limits.
Official LinkGlimpse surfaces
These links identify the website, source, and currently available distribution channels. The MCP release status is stated separately so an unpublished package is never presented as installable.
Source code
The website, diagnostics, CLI, extensions, Actor, and MCP source are available under AGPL-3.0-or-later.
npm CLI
Run URL metadata audits locally or in CI with the published linkglimpse command-line package.
Browser extensions
Inspect the active public tab from Chrome or Firefox without granting browsing-history access.
Apify Actor
Audit up to 100 public URLs per run and export structured diagnostics plus modeled preview images.
MCP source
The multimodal MCP server source is public and tested. Its npm package and official registry listing are not published yet.
Privacy and reproducibility
LinkGlimpse processes the public URL a user explicitly submits. Product analytics reduce submitted URLs to their hostname, while the CLI, browser extension, and local MCP source do not add their own telemetry.
