AI content generation

Generate all domain texts, categories, blog posts, and images with one click. Supports OpenAI, Anthropic, and Google — your choice of provider and model.

Bulk import

Import your portfolio from Afternic, Atom, or Sedo with AI generation running during import. Domains arrive fully filled.

Ready out of the box

After the Setup Wizard, 21 domain categories, 5 pre-built pages, all menus, and core settings are already in place. Import your domains and your portfolio is live.

Page Builder

23 blocks, drag and drop. Edit any page, any text, directly from the admin. No code.

Blog

Write or AI-generate articles to drive organic traffic to your domains.

Built-in analytics

Server-side, AdBlock-proof, GDPR-compliant. No cookies, no consent banner required.

SEO ready

Solid SEO foundation out of the box. High Google PageSpeed scores on both desktop and mobile.

Mobile-first

Every page fully adapted for mobile, fast and comfortable to use. Fonts, spacing, menus, buttons — all tested on real devices.

Fully customizable appearance

Theme, background, fonts, accent colors, border radius — all from the admin.

Notifications

Get notified on new inquiries, offers, and expiring domains via email or Telegram.

Self-hosted

Code on your server. Deploy on Vercel or any VPS with Docker.

AI generation across every content type.

Domains

Two buttons. Every field filled.

Not just a text field with a generate button — generation across domains, categories, blog posts, and images, with full control over provider, model, prompts, and tone.

Generate Content

Generate Content

Fills Tagline, Description, Short Description, Curator Insight, Use Cases, Perfect Match For, Categories, Tags, and Brand Color in one click.

Generate SEO

Generate SEO

Runs separately, using the already-generated content as context. Two-step approach produces noticeably better SEO tags.

TipRegenerate any individual field without touching the rest.
ImportAI generation runs during bulk import — by the time it finishes, every domain is already filled.

Blog posts

Give the AI a title and a brief. Optionally add context (news articles, notes) and select domains from your portfolio to mention and link inside the post.

Images*

Generate domain logos, full-screen background images, and blog post cover images directly from the admin. No designer needed.

* Requires connected Cloudflare R2 storage.

Categories

Same two-button approach — Generate Content and Generate SEO — with context-passing between them for better output.

AI domain assistant

Helps visitors find the right domain.

A chat widget on your homepage that helps visitors find the right domain from your portfolio based on their question. Prompt is fully editable.

More relevant leads, less bounce.

Full control over generation

Provider

OpenAI, Anthropic, or Google — text and image generation can use different providers.

Model

Choose any model from your account — from fast and cheap to the most capable.

AI Persona

A set of instructions that shape voice, tone, and style across all prompts. Pre-calibrated out of the box, editable anytime.

23 editable prompts

All generation templates are fully editable from the admin. Don't like how taglines sound? Edit the prompt — no code.

One import. Every domain, fully filled.

Marketplace exports

Afternic.csv Sedo.csv Atom.xml

Don't waste time adding domains one by one. Export your portfolio from Afternic, Atom, or Sedo and import it directly — Domainer Engine recognizes all three formats automatically.

Paste a list

Need to quickly add a few domains manually? Just paste a list into a text field, one per line, with an optional price — and they're in.

AI generation

AI generation runs during import, so by the time it's done every domain is fully filled and your domains are live on the site.

Diff step

After import, a diff step shows you which domains are in your site but missing from the import file — so you can easily spot and clean up anything that's no longer in your portfolio.

Make it yours.

Domainer Engine offers two types of customization: visual and structural.

Visual

Change theme (light/dark), background style (14 variants), border radius, font, accent colors, CTA button color, and default domain list view — all from the admin. No code.

Page Builder

A custom-built Page Builder with 23 blocks — hero, domain grid, FAQ, testimonials, pricing, blog grid, stats, and more. All content pages on the site are built with it, which means you can edit virtually any text, section, or layout directly from the admin.

Two types of pages:

Regular pages
Created from scratch in the admin by assembling blocks.
Template pages
System pages like the domain page, category pages, and blog index have a fixed core (domain grid, price sidebar, post list) that always renders. Each template has designated zones — Above, Below, Left/Right Column — where you can place any Page Builder block.

So you're not locked into what ships by default: add a CTA above the domain grid, drop an FAQ below it, embed a form anywhere. All from the admin, no code.

Contents

Each blog post page comes with auto-generated Table of Contents, estimated read time, a reading progress bar, and social share buttons — all built in, nothing to configure.

ExampleWriting about the rise of .gl domains? Feed it Greenland news as context, select your .gl domains — article ready in under a minute, with your domains naturally referenced.

Search engines already know your portfolio.

Every SEO requirement is handled automatically — from structured data to sitemaps. Nothing to configure manually.

Here's what was implemented:

Structured data (JSON-LD)

Product schema on domain pages, Organization on the homepage, BreadcrumbList on paginated pages — Google understands your pages as product listings, not just text.

Sitemap.xml

Built automatically — import a domain or publish a page and it appears in the sitemap immediately. No manual maintenance.

robots.txt

Generated automatically and updated as your portfolio changes.

Page Speed

Page speed is an official Google ranking factor — and it directly affects user experience. If your site loads slow, visitors leave.

A lot of work went into performance optimization. Run the test yourself and see the results firsthand:

SEO score is artificially low on the demo. The demo site is blocked from search engine indexing (noindex), which PageSpeed penalises in the SEO audit. On a live production site with indexing enabled, the SEO score is 90+.

Mobile domain catalog

Works great on any screen.

The entire site is fully responsive — every page adapts to any screen size, from desktop to phone.

  • Mobile-first design — built for small screens first, scaled up for desktop
  • Every domain page, offer form, and inquiry form works on mobile
  • Marketplace BIN links and contact buttons are fully tappable
  • All site pages are fully adapted — homepage, domain pages, blog, categories, and custom pages
  • Responsive navigation — the menu adapts to small screens without losing any links
  • Domain catalog filters are optimized for touch — search, sort, and category filters work cleanly on mobile
  • Every page builder block is responsive out of the box
  • No separate mobile version, no extra configuration

Know what buyers are looking at.

Server-side analytics built in — no third-party scripts, no cookie banners required.

Built-in server-side analytics

Accurate, AdBlock-proof, and GDPR-compliant by design — no cookies, no consent banner required. Visitor identity is derived from a salted hash, no raw IP addresses are ever stored.

All the data you need is in your dashboard: page views, referrers, countries, devices, and top-performing domains.

Google Analytics

If you prefer GA4, just add your Measurement ID in settings. A configurable cookie banner is included.

Every offer, every inquiry.
Nothing slips through.

Deal flow, built in.

Three ways buyers interact with your domains:

01Make Offer
Buyers submit an offer directly on the domain page. You counter, accept, or reject from the admin. They get notified either way.
02Inquiry
An open-ended contact form, shown alongside the main CTA when enabled.
03Marketplace BIN links
Afternic, Sedo, Atom. Buyers who prefer a marketplace can go straight there from your page.

The web's current standard.

Built on Next.js and Payload CMS. Next.js is the current standard for modern web development — not PHP, a completely different technology that delivers significantly faster page loads and better performance out of the box.

The public site runs on React and Tailwind CSS, keeping pages lean and fast for every visitor.

Self-hosted — deploy on Vercel or any VPS via Docker.

Personal instance

A private instance already deployed — you start from the Setup Wizard, exactly where you'd land after completing deployment on Vercel or your own server. Enter your own API keys to test AI generation, notifications, and every other feature. Valid for 24 hours.

You'll need to revoke any keys you enter after testing — I don't store them, but the instance is yours to control.

Common questions.

Vercel — moderate. If you've never deployed a web app before, it may take a while. You can judge the complexity yourself before buying: Vercel deployment guide →

VPS — advanced. But that's true for any self-hosted app — running your own server is inherently a technical path.

For Vercel: a free Vercel account and a free Neon database. That's it — no server to manage. For Docker: any VPS with Docker support. All third-party services (AI, email, Telegram, analytics) are configured through the admin panel after deployment.
Only for AI-generated and uploaded images — domain logos, backgrounds, and media uploads. Cloud storage is optional: the platform runs fully without it. All text content, categories, pages, and deal flows work without storage connected. Cloudflare R2 is the officially recommended provider.
OpenAI, Anthropic, or Google AI — you pick one and connect your own API key. Usage is billed directly by the provider. Google AI has a free tier to get started. Image generation requires OpenAI or Google AI. You can switch providers at any time from the admin panel.
Yes — one payment, yours forever. No subscription, no renewal, no per-domain fees, no usage limits. The only ongoing costs are services you choose to connect: hosting (Vercel free tier works), AI API usage billed directly by the provider, and optionally cloud storage and email delivery.
Your content, settings, and customizations are never touched — only the core platform is replaced. On Vercel or Docker (recommended), updating takes a click or two with zero to 30 seconds of downtime. ZIP deployment is not recommended — it requires manual file replacement and a full rebuild, with several minutes of downtime.
The license covers a single installation, used by the buyer. Extended licenses for multiple sites or agencies are available separately — contact me directly.
No. Domainer Engine works alongside your marketplace listings. Each domain page can show BIN links to Afternic, Sedo, and Atom — buyers who prefer a marketplace go straight there. Your portfolio site and your marketplace presence work together.
Direct payments via Stripe are planned but not yet available. For now, deal flow runs through Make Offer, Inquiry, and marketplace BIN links. This may be added in a future update — no timeline or guarantee.
Describe what you need and contact me directly — I consider all requests.
No refunds on digital purchases — this is standard for marketplace scripts. Before buying, test the open demo or request a personal instance to try the full platform with your own API keys. If something doesn't work as described after purchase, contact me directly and I'll resolve it.
