## Description

[DESCRIPTION]
Alt Cloud is an open directory of cloud services that are genuinely transparent: public pricing, self-service signup, and a visible status page. Alt Cloud Checker tells you, at a glance, whether the site you're looking at is in the directory — and if it isn't, lets you suggest it with one click.

<strong>Five status indicators</strong>

The toolbar icon shows one of five states:
<ul><li>🟢 <strong>Listed (3/3)</strong> — meets all three transparency criteria</li><li>🟡 <strong>Listed (2/3)</strong> — partial; the popup tells you what's missing</li><li>🔵 <strong>Future Cloud</strong> — on the watch list, not yet meeting all criteria</li><li>➕ <strong>Not listed</strong> — one click to suggest it via a prefilled GitHub issue</li><li>⚪ <strong>Unchecked</strong> — internal pages, search engines, code hosts, social platforms</li></ul>
<strong>In the popup</strong>

Service name, category chip, per-criterion transparency breakdown, and action buttons — view the entry on <a href="https://prod.outgoing.prod.webservices.mozgcp.net/v1/ec292d86d31e762c8c882cb4109c02718491ffbeeb380ba82594b04598d05fbe/http%3A//alt-cloud.org" rel="nofollow">alt-cloud.org</a>, report a correction, or (for Future Clouds) suggest they graduate. For unlisted sites, a one-click flow opens a prefilled GitHub submission you review before posting.

<strong>Three transparency criteria</strong>

To be fully listed, a service must meet all three:
<ol><li><strong>Transparent public pricing</strong> — prices visible without signing up or contacting sales</li><li><strong>Usage-based self-service signup</strong> — no sales call required to start</li><li><strong>Production indicators</strong> — public SLA, status page, or uptime tracker</li></ol>
Services meeting two of three appear as partial listings. Promising services that don't yet meet the bar appear on the Future Cloud watch list.

<strong>Privacy</strong>

The extension collects nothing and sends nothing. The sole network request is a daily fetch of the public directory at <a href="https://prod.outgoing.prod.webservices.mozgcp.net/v1/ee6609ed170436f360cfae0bd9f4a19b4e622e153445090529d5b1a48f739444/http%3A//alt-cloud.org/clouds.json" rel="nofollow">alt-cloud.org/clouds.json</a>, cached locally for 24 hours. Page metadata (title, Open Graph tags, favicon) is read only when you open the popup on an unlisted site, used only to pre-fill the suggest form, and never transmitted automatically. Full details in the privacy policy.
