How it works

What this score really means

  1. 01

    Answer 6 questions about your site

    Tell us your platform, how many plugins or apps you're running, whether you have forms or payment pages, how often you make changes, what share of visitors are on mobile, and when you last tested the site.

  2. 02

    Each answer maps to a weighted risk score

    We assign risk points to each answer based on how strongly that factor correlates with real-world regression failures. WordPress with 20+ plugins scores much higher than a simple Webflow site that rarely changes.

  3. 03

    Scores combine into a 0–100 risk rating

    All weighted scores are summed and capped at 100. Below 26 is Low Risk, 26–50 Medium, 51–75 High, and 76–100 Critical, with thresholds calibrated against common regression failure patterns.

  4. 04

    Specific risks are surfaced in plain English

    We identify which factors are pulling your score up and explain exactly what could go wrong, so you know which pages, forms, or integrations to test first after your next update.

FAQ

Questions about this tool

We assign weighted points to each of your answers based on how strongly that factor predicts regression failures in practice. The points are summed and capped at 100, then mapped to Low / Medium / High / Critical risk tiers.
A regression is when an update to your website accidentally breaks something that was working before, like a contact form that stops submitting, a layout that collapses on mobile, or a payment page that starts throwing errors.
Start by testing your most critical pages (homepage, contact form, checkout) on both desktop and mobile immediately after your next update. Even a 10-minute walkthrough catches most regressions before your visitors find them.
WordPress has a larger regression surface: core updates, plugin updates, and theme updates can all conflict independently. Webflow's managed infrastructure removes most of that complexity. Custom codebases score highest because there is no CMS safety layer at all.
Yes. Every change Tuesday makes is followed by a QA pass across all affected pages on both desktop and mobile before we mark the task complete. Forms are submitted end-to-end and layouts are checked at standard breakpoints. That's how we maintain our 4.9★ Clutch rating.
