You build it.13x does the rest.
13x audits your live site for the metadata, sitemaps, structured data, social previews and legal pages your build skipped — and returns ready-to-paste fixes for your stack.
No signup. Results in 30 seconds.
You build the product. 13x makes it market-ready.
The problem
The build took a week. The launch never happened.
AI ships your product fast. What it doesn't do is write a sitemap, give every page its own title, generate an OG image, or tell you that loading Google Fonts from a CDN is a GDPR problem in half your addressable market. None of this is hard. All of it gets skipped, because no coding agent reminds you.
How it works
Other tools ask what your product does. We read it.
13x analyses your actual product and derives the fixes from it, instead of handing you a form to fill in. Today from your live URL. Soon straight from your repo, as a pull request you just merge.
Every other tool
- “What does your product do?”
- “Who is your audience?”
- “Paste your keywords.”
- “Describe your tone of voice.”
You do the work of describing what you already built.
13x
- GET /
- GET /robots.txt
- GET /sitemap.xml
- HEAD /og.png
We read the product. You get the fixes.
What gets checked
Twelve groups, ninety-seven checks, one report.
Every finding comes with what is broken, what it costs you, and the fix for your framework. Three of these groups are ones no other audit covers.
Discoverability
robots.txt, sitemap, canonical URLs, broken internal links, redirect chains, and the accidental noindex that keeps a finished site out of every index.
AI visibility
Only hereWhether GPTBot, ClaudeBot, PerplexityBot and Google-Extended can reach you, whether your content exists without JavaScript, and whether it is shaped to be quoted.
Compliance
Only herePrivacy policy, Impressum, consent before tracking, Google Fonts from a CDN, California opt-out, withdrawal rights. Detection, never legal advice.
Email deliverability
Only hereSPF, DKIM, DMARC and MX. You launch, you send a welcome email, it lands in spam — and nothing tells you.
Metadata
Titles and descriptions per page, duplicates across pages, and the scaffolding titles that survive to production.
Social & sharing
Open Graph tags, whether your og:image actually loads and whether it is the right size, Twitter cards and favicons.
Structured data
JSON-LD presence, the type you declared, and whether its required properties are filled.
Security
HSTS, CSP, cookie flags, mixed content, subresource integrity and outdated libraries. Read from headers, never by probing.
Accessibility
Alt text, form labels, disabled zoom, heading order and landmarks — plus the EU accessibility statement in force since June 2025.
Performance
Compression, render-blocking scripts, images without dimensions, legacy formats and document weight. Causes, not guessed metrics.
Conversion
Email capture, a contact route, analytics, a visible price and social proof. Advisory rather than scored hard.
Basics
HTTPS, certificate expiry and host coverage, TLS version, redirects, real 404s, domain expiry and time to first byte.
Why one tool
One subscription, not five.
A screenshot tool, an SEO tool, a policy generator, a directory submitter, an ASO tool. Five subscriptions for one launch, and you do it all again next month. 13x is one project, one checklist, unlimited launches.
What a launch costs today
- Screenshot tool$15/mo
- SEO audit tool$30/mo
- Policy generator$12/mo
- Directory submitter$25/mo
- ASO tool$20/mo
A report helps once. A launch record improves the next one.
