Webflow site audit app, 18 checks in one score.
A Webflow site can look finished and still fail WCAG contrast, leak SEO and drift off your design system. HewnFlow grades the page against 18 deterministic checks before you hit publish, so you never ship the mistake that costs you a ranking or an accessibility complaint.
From the empty panel to a score you can act on.
Open the app on any page in the Designer, hit Run, read the score. Every finding carries a stable check ID, and nothing leaves Webflow.

What does HewnFlow check on a Webflow site?
HewnFlow runs 18 deterministic checks across three categories: accessibility to WCAG 2.2 AA (colour contrast with real luminance math and alpha blending, image alt text, heading hierarchy skips, multiple h1, generic link text, form-input labels), on-page SEO (title and meta description length, cross-page duplicate titles and metas, OG image, canonical URL) and design-system drift (raw hex colours not bound to Variables, fonts and font sizes off your scale, spacing off the 4n scale, dead classes). Every finding carries a stable check ID like a-006 or ds-004.
Is HewnFlow free?
Yes. The free tier runs the 13 accessibility and SEO checks on the current page with unlimited audits and no account. Pro is $19 per month and adds the 5 design-system checks, site-wide sweeps for cross-page duplicate titles and metas, a WCAG-mapped PDF report, an EU accessibility statement generator and 3 device activations per license. Agency is $49 per month and white-labels the PDF report under your studio name.
When can I install HewnFlow?
HewnFlow has been submitted to the Webflow Apps marketplace and is in review. Join the waitlist on this page and we will email you the install link the day it is approved.
Does my site data leave Webflow?
No. The audit runs inside the Webflow Designer on your machine. The only network calls validate your Pro license; no element names, class names or project content are sent. Telemetry is limited to check IDs and counts and can be switched off in Settings.
How is HewnFlow different from Webflow's built-in audit panel?
The built-in audit covers a handful of accessibility basics. HewnFlow grades the page 0 to 100 against 18 checks, including WCAG contrast computed from real luminance, on-page SEO with cross-page duplicate detection, and the design-system layer nobody else audits: colour drift against your Variables, off-scale type and spacing, dead classes. Each finding has a stable ID, so the score is deterministic and comparable run to run.
What is your refund policy?
Full refund within 7 days, no questions asked: email support@hewnpath.com with your license key. You can cancel the subscription anytime from your Polar customer portal. Consumers in the EU also keep the statutory 14-day right of withdrawal, which our faster policy sits on top of rather than replaces. Details in the terms.
