From sign up to results in a few easy clicks.

Step 01

Create an account

Sign up and verify your email to get started.

Step 02

Step 03

Run the scan

It's as easy as clicking the run button and waiting.

Step 04

Fix & verify

Comparison

Why use Areion instead of a patchwork of tools?

See code quality, security, and link health in one place—without stitching together separate reports.

Typical setup Areion
Unified health score Different tools, different scores—hard to compare One overall grade plus per-module breakdown
Lint · HTML, CSS & JS Editor plugins and one-off checks—easy to miss pages Lint runs across the pages we crawl
Security posture Headers checkers, ad-hoc scans, easy to miss pages Shield uses the same crawl as Lint and Crawl
Broken links & routes One-off crawlers or manual clicking Crawl maps internal links in one pass
Findings you can fix Generic messages; mapping to your repo is on you Findings with enough context to act on

FAQ

Common questions

Do I need to install anything?

No. Areion runs in the browser—sign in, paste a URL, and you’re scanning. Nothing to download for the web app.

How is this different from Lighthouse or a linter?

Lighthouse excels at performance; linters often focus on one language. Areion combines Lint, Shield, and Crawl in one run so you get one scorecard instead of three separate stories.

Will scans slow down my live site?

Scans run from our side when you start them—they aren’t embedded in your pages and don’t add load for your visitors.

Is my data or my users’ data sent to third parties?

We don’t sell your scan data. For what we store and how long, read the privacy policy.

Documentation

Using Areion in the browser

Areion is a single-page web app: you sign in, run analyses, and read results without installing a CLI or browser extension. This page describes how the product is organized today and how to get the most out of each module.

Quick start

1. Create an account or sign in. 2. Open Run analysis from the workspace sidebar. 3. Paste a full URL (include https://), run the scan, then open Results for module scores, activity, and your latest analyzed URL.

Workspace layout

After sign-in you get a left sidebar: Overview (KPIs and shortcuts), Run analysis (scanner), Results (scores + table), Settings (account profile), and Billing (plan and credits). The marketing footer is hidden in the workspace so the app can use full viewport height.

URLs & routing

The app uses hash routes, for example #dashboard, #analyze, #results, #docs, #pricing. You can bookmark or share a link to a section; protected routes redirect to #sign-in if you aren’t authenticated.

Data on your device

Your latest run (URL, timestamp, module scores, and findings count) is cached in this browser so Results can load quickly. Clearing site data removes local history. Plan and scan credits sync from your account metadata in Supabase.

Getting started in depth

Use a URL you’re allowed to test—staging, preview deploys, or public marketing sites are ideal. The in-browser scan scores real page signals from fetched HTML (quality, security, and crawlability heuristics) and highlights issues found in that snapshot.

After each completed run, check Results for the bar chart (synced to that run), the activity line with URL and time, the table row for “last analyzed,” and—when the fetch succeeds—Fetched page HTML with the markup we pulled for that run (stored locally, may be truncated). On Run analysis, expand “View fetched page HTML” under findings for the same snapshot.

The three modules

Lint stands in for HTML, CSS, and front-end hygiene checks—messy markup, outdated patterns, and consistency issues that are easy to miss in review.

Shield represents security-oriented signals you’d normally chase in multiple tools: headers, cookies, mixed content, and similar basics that should be true on every deploy.

Crawl focuses on link and route health—broken internal links, obvious traps, and structural issues that confuse users and search engines.

Together they produce one overall score plus per-module scores so you can see whether you’re failing on quality, security, links, or a mix.

Scan settings (roadmap)

Scans run all three modules in one pass. Future controls will include module toggles, crawl-depth caps, and ignore lists (paths, third-party hosts, noisy rules) so larger sites remain manageable.

Plans, scans & billing

Pricing tiers on the Pricing page describe illustrative scans and history windows. The in-app Billing page reads your current plan label from user metadata when present; otherwise it shows “Free” and explains that payment methods and invoices appear once you connect a provider.

Account & security

Authentication uses Supabase email/password. Use a strong password and sign out from the header or sidebar when you’re on a shared machine. For processing and retention details, read the privacy policy.

Troubleshooting

  • Stuck on sign-in after clicking Dashboard: Complete sign-in first; the app redirects back when a session exists.
  • Results never update: Ensure the scan finishes (button returns to “Re-analyze”), and that third-party cookies or storage aren’t blocked for this origin.
  • Blank workspace: Hard-refresh once; if a hash doesn’t match a known route, the app falls back to the marketing home.

Roadmap & integrations

We’re prioritizing the in-browser experience, honest empty states, and account-backed scan history. APIs, webhooks, Slack notifications, and org-wide policies are on the long list—if you have a concrete need (SSO, export format, CI token), email hello@areion.dev with your stack and timeline.

Company

We’re building for people who ship websites.

Areion started from a simple frustration: quality, security, and links are usually three different conversations. We’re trying to make them one—without turning your week into a spreadsheet and a dozen browser tabs.

About us

We’re a small team obsessed with the gap between “we should check that” and “we actually checked it.” Most teams know they should care about markup quality, headers, cookies, and broken links—but those checks are easy to defer until something breaks in production or an audit lands on someone’s desk.

Areion exists to shrink that gap. We care about clarity: scores and findings you can explain to a teammate, not jargon that only a specialist can parse. We care about focus: surfacing what matters for the URL you’re looking at, not a thousand noisy alerts. And we care about meeting you where you work—in the browser, with flows that feel fast and intentional rather than bolted on.

We’re early. The product will evolve, but the direction won’t: help builders ship sites they’re proud of, with fewer surprises after deploy.

What we care about

Actionable output. Every report should answer “what should I do next?”—with enough context to prioritize, not just enough data to feel overwhelmed.

Plain language. Security and quality matter to everyone on a team, not only to people who live in RFCs. We write for humans first and link to the deep cuts when you want them.

Respect for your time. Fast paths for common tasks, sensible defaults, and honest limits when something isn’t ready yet. No dark patterns, no fake urgency.

Privacy-aware design. We assume you’re scanning real URLs and real properties. We describe what we process, how long it might be retained, and how to ask questions—see our privacy policy for the details we publish today.

How we work

We ship in small iterations: tighten the scan experience, improve how results are explained, and expand coverage where it helps the most people. Feedback from people who run sites—agencies, indie makers, platform teams—shapes what we build next.

If you’re evaluating Areion for a team, we’re happy to talk through your workflow, what you’re trying to catch before release, and how we can fit (or where we’re not the right tool yet).
