Comparison
Why use Areion instead of competitors or multiple tools?
See code quality, security, and link health in one place—without stitching together separate reports.
| Typical setup | Lighthouse | Areion | |
|---|---|---|---|
| Unified health score | Different tools, different scores—hard to compare | Multiple scores on one program and only scores specific criteria | One overall grade plus per-module breakdown |
| Lint · HTML, CSS & JS | Editor plugins and one-off checks—easy to miss pages | Checks your code but does not go into depth | Lint runs across the pages we crawl |
| Security posture | Headers checkers, ad-hoc scans, easy to miss pages | No security scores or findings | Shield uses the same crawl as Lint and Crawl |
| Broken links & routes | One-off crawlers or manual clicking | No link health scores or findings | Crawl maps internal links in one pass |
| Fixing your findings | You may have to use AI or your own tools to fix your findings | Same here; no fixing your findings | Fix your findings in less then 1 minutes with our built-in fixer* |
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 and its analysis tools are designed to be used in the browser so you won't need to install anything and waste more precious storage on your device. This documentation will teach you how to use our tools inside the browser or inside of an IDE.
Quick start
1. Create an account or sign in. 2. Open Run analysis from the workspace sidebar. 3. Paste a full URL and include https:// in the URL, run the scan, then open Results for module scores, activity, and your latest analyzed URL.
Workspace layout
After sign-in you will open in the dashboard where you can see your latest analysis and your scan history. You will be able to run a new analysis by clicking the Run analysis button and you may search the side bar for other tools and pages.
Data on your device
Your latest run (URL, timestamp, module scores, and findings count) is cached in this browser. Plan and scan credits sync from your account metadata in Supabase.
Getting started in depth
When using Areions analysis tools only use a website you are allowed to test. Areion will not be responsible for any damages or legal issues caused by the user. Our analysis tool is very powerful and can view the entire codebase of your website, please use with caution.
After each completed run you may check the Results tab to see in depth results and information about your findings or click the fix tab to get recomendations on how to fix your findings. You also may open up the Areion Studio to experiment with your code and fix any problems you face.
The three modules
Areion has three and counting modules that are designed to help you audit your website and fix problems your website may have.Lint stands in for HTML, CSS, and front-end hygiene checks and obviously linting errors.
Shield represents security-oriented signals you’d normally chase in multiple tools. Shield uses real information from many security leaks to help prevent leaks.
Crawl focuses on making sure the entirety of your website is accessible. Crawl will literally crawl your website and find broken links, redirects, and other issues that may be in your code.
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.
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.

We’re building for people who ship websites.
About us
Areion is a really small team of developers AKA 1 person and we (I) wanted to create a tool that would help developers like you create better websites and fix problems that can be super small, but they can impact the entire website.
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.
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 and terms of use.
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).
Contact
Our "almost all" service email: support@areion.devWhen your email is sent we'll send you in the right direction. Complaints or suggestions? we'll handle that. Trouble logging in? We can also handle that.

Questions: privacy@areion.dev
Legal
Terms of Use
Last updated May 2, 2026. These Terms govern access to areion.dev, the Areion web application, and related services (together, the “Service”). They apply together with our Privacy Policy. If you use the Service on behalf of a company, you represent that you have authority to bind that company.
1. Using the Service
We grant you a non-exclusive, non-transferable right to use the Service during an active account or trial, subject to these Terms and any plan limits shown in the product or on the pricing page. You must comply with applicable law. We may refuse registration, close accounts, or restrict features when we reasonably believe it is necessary to protect the Service, other users, or third parties.
2. Accounts
You provide accurate account information and keep sign-in credentials confidential. You are responsible for activity under your account unless you notify us promptly at support@areion.dev after learning of unauthorized access. Do not share accounts in ways that let multiple unrelated organizations share one paid allowance unless your plan explicitly allows it.
3. What Areion does
Areion analyzes URLs you submit: for example HTML/CSS/JS checks (Lint), security header and related signals (Shield), and internal link routing (Crawl), plus in-app helpers that suggest edits (Fix). Output is generated automatically from fetched content and configuration we can observe. It is not a manual penetration test, legal compliance audit, or accessibility certification unless we separately agree in writing.
4. Scanning rules
You may only submit URLs you are allowed to test. That includes sites you own, sites where you have written permission, or public pages where automated access is permitted and proportionate. You will not use the Service to probe third-party systems without authorization, to violate robots.txt or similar rules where they apply and you are required to follow them, to launch denial-of-service attacks, or to harvest data unrelated to legitimate quality or security review of your own properties.
We may throttle, queue, or stop scans that appear abusive, illegal, or harmful to our infrastructure or to third parties.
5. Your data and license to us
You keep your rights in URLs, scan requests, and results stored in your workspace. To operate the Service, you grant us a limited license to host, process, transmit, and display that material solely to provide and improve the Service for you, as described in the Privacy Policy. Suggestions produced by Fix are generated for your use on your projects; you decide whether to apply them.
6. Third-party sites
When you point Areion at an external URL, you understand that we fetch and analyze that content on your instruction. We do not control third-party sites and are not responsible for their availability, accuracy, or policies.
7. Fees and trials
Paid plans, taxes, invoicing, and refunds follow the checkout flow and payment provider you use. If a price or allowance changes, we will use reasonable means to tell you before the change hits your next renewal where the law expects notice. Downgrades may reduce history or scan limits immediately or at period end depending on how billing is implemented in your account screen.
8. Disclaimers
The Service is provided on an “as is” and “as available” basis. We do not warrant that scans will be complete, error-free, uninterrupted, or that following a suggestion will fix a production issue or satisfy a regulator. Scores and findings are informational. You remain responsible for your deployments, disclosures, and security posture.
9. Limitation of liability
To the fullest extent permitted by law, neither Areion nor its suppliers will be liable for indirect, incidental, special, consequential, or punitive damages, or for loss of profits, data, or goodwill, arising from these Terms or the Service. Our aggregate liability for claims arising out of the Service in any twelve-month period is limited to the greater of (a) amounts you paid us for the Service in that period or (b) fifty U.S. dollars if you used only free access. Some jurisdictions do not allow certain limitations; in those cases our liability is capped at the minimum allowed.
10. Indemnity
You will defend and indemnify Areion against third-party claims and costs (including reasonable attorneys’ fees) that arise from your misuse of the Service, your violation of these Terms, or your scanning of URLs without proper rights or consent.
11. Intellectual property
Areion owns the Service, including software, branding, documentation, and aggregate analytics that do not identify you. Except for the limited right to use the Service, these Terms grant you no license to our IP. Feedback you give us may be used without obligation or compensation to you.
12. Termination
You may stop using the Service and request account deletion as described in the Privacy Policy. We may suspend or terminate access for breach of these Terms, non-payment where applicable, risk to the Service, or extended inactivity if we announce such a policy. Provisions that by nature should survive (disclaimers, liability limits, indemnity, governing law) survive termination.
13. Changes
We may update these Terms by posting a new version on this page and updating the “Last updated” date. For material changes we will also use reasonable notice paths (for example email to your account address or an in-app notice). Continued use after the effective date constitutes acceptance unless the law requires express consent.
14. Export and government users
You may not use or export the Service in violation of U.S. or other export control or sanctions rules. If you are a U.S. government entity, the Service is commercial computer software; use is subject to these Terms only, not government-wide acquisition clauses unless we sign a separate agreement.
15. General
These Terms and the Privacy Policy are the entire agreement between you and Areion about the Service. If a provision is unenforceable, the remainder stays in effect. Failure to enforce a provision is not a waiver. You may not assign these Terms without our consent; we may assign them in connection with a merger or sale of assets.
Unless mandatory local law says otherwise, these Terms are governed by the laws of the State of Delaware, USA, without regard to conflict-of-law rules. Courts in Delaware have exclusive jurisdiction, and you consent to personal jurisdiction there.
