Aether is a Claude Code plugin that scans your site for WCAG 2.1 AA violations with Playwright and axe-core, then returns grounded, verifiable fixes — every cited WCAG technique passes an ontology grounding gate, so nothing is invented. The private beta gives you a personal API key for the hosted fix engine, free, for 45 days at a time.
What the plugin sends to our cloud
The scanner (Playwright + axe-core) runs entirely on your computer. Only when the plugin requests a fix, or you submit feedback, does it call Allchemy's insights API on Google Cloud (us-central1). Each request carries the HTML of the failing element, up to ~2 KB of surrounding DOM (parent, children, siblings), the page URL including its query string, and, for feedback, your rating and any correction you type. We do not send screenshots, cookies, request headers, form values, or the full page.
Fix requests are processed in memory and not stored; the URL is written to request logs, and
feedback is retained to improve fix templates. Fixes come from a model we run on our own
infrastructure — nothing is shared with a third-party LLM provider. Scanning a private or
authenticated app? Strip secrets from URLs first, or run with maxFixes: 0 to scan
with no network calls at all. Your GitHub access token is used once, here, to read your
profile and verified email, then discarded.
Who gets in automatically
- GitHub accounts at least 30 days old with a verified primary email.
- While the current wave has seats. Otherwise you join the waitlist and we release seats in order.
- One key per GitHub account. Sign in again any time to rotate it.
What a scan result means
Aether is an accessibility analysis and guidance tool. Using it does not, by itself, make your website, application, or digital service conformant with WCAG, the ADA (including Title II), the European Accessibility Act, Section 508, EN 301 549, or any other accessibility law or standard. Automated scans detect only a subset of accessibility barriers: a “zero issues” result means the scanner did not flag anything in its detection range, not that the property is legally compliant.
You remain responsible for reviewing findings with qualified people, fixing issues in the underlying code and content, conducting or commissioning manual testing and audits as needed, maintaining accessibility as the product changes, and obtaining legal advice for your specific obligations. Aether does not provide legal advice and does not replace an accessibility audit or a VPAT/ACR prepared by a qualified auditor. See our legal notice.
