Comparison
axle is the source-code alternative to UserWay.
UserWay sells an accessibility overlay: a JavaScript widget that tries to retrofit accessibility over broken HTML at runtime. The same category of product cost accessiBe a $1 million FTC settlementin January 2025 for deceptive compliance claims. Plaintiff's lawyers now cite overlay presence as evidence of bad faith, not as mitigation.
axle takes the opposite approach: scan in CI, propose source-code fix diffs via Claude, generate the legal artifacts your compliance officer needs.
Side-by-side
| UserWay widget | axle | |
|---|---|---|
| What it does | Injects JS at runtime, attempts to add ARIA / adjust contrast / alter keyboard behaviour on top of existing HTML | Scans in CI, proposes source-code diffs, posts them on your PR, blocks merge on regressions |
| Runtime JS on your page | Yes — one extra third-party script | No — zero runtime footprint |
| Source-level fix suggestions | No | Yes — Claude-generated diffs, reviewed before merge |
| Legal defence value | Cited as bad-faith evidence in ADA lawsuits; FTC case law stands | Audit trail of scan reports + published verified statement URL |
| Screen-reader experience | Can actively harm NVDA / JAWS users (Princeton 2023 study) | No runtime interference — improves only what's fixed at source |
| Cost | $490/yr starting (public pricing) | $0 free tier · $49/mo Team |
| Works for WP / Shopify / headless | Widget script, theme-agnostic | GitHub Action, npm CLI, Netlify / Cloudflare / Vercel plugins, WP plugin |
Why overlay tooling is dead
Four independent pressure points converged on widget-based accessibility in 2024-25:
- The FTC settlement with accessiBe($1M, January 2025) over deceptive "AI-powered WCAG compliance" claims — legal template for future suits against any overlay vendor.
- The Princeton study (Van Lee et al., 2023) documented cases where overlay-injected ARIA actively harmed screen-reader users.
- EAA 2025(EU-wide, enforceable 28 June 2025) references EN 301 549 — which evaluates the served HTML, not runtime behaviour. Overlays don't move the compliance needle.
- Plaintiff's-bar collective experience — law firms that file ADA accessibility suits now have boilerplate that cites overlay presence as aggravating rather than mitigating.
