# 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 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.

## 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](https://www.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 The MCP release status is stated separately so an unpublished package is never presented as installable.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.

## 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.
