Why Sienna is the Right Choice for Your Website

When it comes to web accessibility, most providers follow a “SaaS” (Software as a Service) model. They charge you every month, forever, often starting at $49/month. That’s nearly $600 per year for a script that often fails to provide true accessibility.

Sienna is different. Here is why we are better than the rest.

1. Predictable Pricing

We don’t believe in rent-seeking for accessibility, but we do believe in sustainable software.

The Others: $490 - $3,500+ per year. If you stop paying, the accessibility tools vanish. Most also charge more as your traffic grows.
Sienna: A transparent monthly fee (billed annually). Unlimited pageviews included—we never charge you more for being successful. Once you buy it, you’re covered for the year.

2. Zero User Tracking & 100% Privacy

Most “AI-based” accessibility tools track your users to build data profiles. They use cookies and scripts that monitor behavior.

The Others: Privacy policies that allow data sharing and behavioral tracking.
Sienna: Bridge directly to your own Google Analytics (GA4) without user tracking on our servers. No cookies, no 3rd-party data logging. You own your user data.

3. Open Source & Transparent

You shouldn’t have to trust a “black box” script with your website’s security and performance.

The Others: Proprietary, obfuscated code that you cannot audit.
Sienna: Fully open source. You can inspect every line of code on GitHub. You can self-host the script on your own servers to eliminate external dependencies entirely.

4. Performance & Core Web Vitals

Sienna is designed to have a minimal footprint until it is needed.

1-Minute Install: Just one line of code.
No Performance Bloat: Only 64KB, compared to 100KB-200KB for traditional corporate overlays. We don’t load heavy AI models that slow down your initial page load. Our widget is highly optimized for Core Web Vitals and SEO.

5. Transparent Pricing

We don’t hide our prices behind a “Book a Demo” button.

Free: Open Source & Unlimited usage.
Pro: $3.25/mo for white-labeling.
Business: $6.58/mo for agencies up to 10 websites.
Enterprise: $33.25/mo for unlimited websites, commercial use, and full self-hosting. (All plans billed annually)
