Not just the screen —
the workings.

Payment gets approved, a booking holds, members add up — only then is the handover done. This is hosting with those workings built in advance and verified on real services. Hand us the whole build, or attach them yourself to screens your usual AI already made.

Workings that attach now
Forms, members, boards and conversion tracking are already running live.
Payments are demo-verified right up to the real checkout screen.
For the 3–5 pilots, the founder is hands-on for the initial setup.

§ 01 · Screens in operationHonesty labels
If you wanted to see the real thing before you trust it

Substance over talk

The sites below are live or running in demo right now. We label only as far as we've verified — what we haven't checked, we don't claim here either.

Haengbokdream catering, live site screen.
Members · board live Corporate catering, Haengbokdream. A site where sign-up and the board actually run live.
Seoul Sleep Center English site, board screen.
Board live Sleep clinic, English site — Seoul Sleep Center. 173 posts running on the content backend.
NOVARI shopping demo, payment flow screen.
Payment simulated Shopping demo, NOVARI. A demo that runs the flow to the Toss checkout window; payment is simulated.
Songam Law Firm, client site screen.
Client site Songam Law Firm. A screen the client uses; we don't claim backend workings here.
100명Total members across live sites on Saeroon
251건Total posts across live sites on Saeroon
173건Seoul Sleep Center posts running on the content backend

Label rules: 'in operation' goes only on workings that run live, 'simulated' only on demos where we verified the flow alone. Saeroon's own services run on this too. The 100 members and 251 posts are the totals across all live sites on Saeroon.

§ 02 · Workings that attachBy verification stage
If you needed to check before making a promise

What works, and what's not yet

For each working, we've written down plainly whether it's live, demo-only, or just pipeline-ready. Check this table before you promise anything to a client. What isn't ready, we mark as not ready here too.

It isn't bolting payments, booking and members on one by one — it's wiring them to mesh and run together inside one site. Without writing new code.

As each verification finishes, this table updates first. Labels reflect measurements taken in 2026-07.

If a project needs payments or booking, it's faster to agree the scope first and then start. Talk through scope →

§ 03 · How we workHand it over · build it yourself
If you wanted to keep your pipeline as it is

Hand it over, or build it

Every agency's build pipeline is different, so both ways are open. Start on one side and move to the other, or mix them site by site.

Hand it overWe build it, and we own what comes after

Web or app, we build it from screen to workings. After handover, edits and operations are looked after with you at no charge, and the founder responds to campaign schedules personally. Start with a single overflow job — no need to switch the vendor you already use.

  • Web and app builds — for apps, store release and the backend too
  • Edits and operations free; only new features are quoted separately. One party owns it, so nothing falls through the cracks
  • A dashboard where, even after handover, your client sees inquiries, members and boards directly
  • Work runs on a signed contract, and your client keeps dealing with your agency as their point of contact
Inquire about a build →
Build it yourselfKeep your AI — just attach the workings

Your team builds the screens with the tools it already uses, and attaches forms, members, boards and conversion tracking with one line of HTML attributes. Deploy in one CLI line; build, attach and operate through MCP.

  • Forms, members and boards with nothing but data-saeroon-* attributes
  • Reports and email in your agency's brand (white label)
  • No lock-in (assets leave freely · 30-day grace on cancellation)
See the developer center →
After handover, the operations console your client sees directly

Form submissions, members and boards gather in one console. Below is that console's inbox and member list, drawn with sample data.

§ 04 · Developer centerDocs the AI reads first
If attaching it always got you stuck

One address for your team's AI

Teams building it themselves just hand their usual AI the developer-center address. The AI reads the attributes and commands for attaching forms, members, boards and payments from the docs, and wires them up as written.

We audited whether it runs start to finish in one session with no prior knowledge (12/12). The docs and command reference are written for the AI to read before a human does.

11 documentsForms, members, boards, payments, marketplace — every way to attach them
40 attributes · 26 CLI commandsThe data-saeroon-* attribute and CLI command reference (auto-generated)
Remote MCP · OAuthThe AI builds, attaches and operates directly within the site's scope. Underneath it's the same REST API, so you can issue a key and call it yourself too
Replication tools · template marketplaceReference analysis and visual comparison (analyze · compare · verify), plus template registration and reuse (register · sync)
The real attach code
Markup
<form data-saeroon-form="inquiry"> … </form>
<form data-saeroon-auth="login" data-redirect="/account/"> … </form>
Screen
SendLog in
Form and member attributes — this exact markup is running on live sites.

When you build it yourself, the sticking point is usually 'how do I attach this?' Once your team's AI finds that answer straight from the docs, the human only has to decide whether to attach it or not.

§ 05 · PricingFlat monthly per site · excludes VAT
If you needed numbers you can put straight into a quote

The price list, as numbers

When a site starts doing more, that's when you move it up. Only past 20 sites does pricing open to negotiation. The monthly rates below are the same whether you hand the build over or build it yourself — a done-for-you build adds a one-time project fee.

Build costs vary site to site, but hosting and the workings are recurring. Long-term quotes only hold when the recurring cost is predictable.
TierPer site · monthlyWhat's included
StaticLanding and brochure sites₩9,900Screens and static hosting + inquiry forms + automatic conversion tracking
WorksSites with forms, members, boards₩14,900Members, boards, forms, booking — the workings included
CommerceSites that take real payments₩29,900Payments, orders, shop (+ 1% of GMV)
Demo-verified Payment workings are currently at the demo-verification stage. The 1% applies only to amounts actually settled; scope, timing and setup are walked through in consultation. Booking intake, confirmation and double-booking prevention are live in the Works tier; only the settlement on bookings that carry a prepayment or deposit sits at the same demo-verification stage as payment.
Volume discounts
  • −20% from 5 sites
  • −30% from 20 sites · beyond that, negotiated
  • Example: 10 Works sites = ₩119,200/month (14,900 × 10, −20%)
Also included
  • 2 months free on annual billing
  • Unlimited free staging · 14-day trial. There is no separate free tier — getting started begins with an inquiry.
  • White label covers reports, email and the client view, plus separated billing (free at 10+ sites, ₩30,000/month below that)
  • Agency account and dashboard are free. Base subscription ₩0 — you are billed only for the sites you put on.
§ 06 · Contact · who builds itOne person responds

Either way, start here

It's fine if you haven't decided yet whether to hand it over or build it yourself. If you have a reference, leave the link. Replies come within about an hour during business hours, from the person who builds and runs it.

How to proceed

What happens after you inquire

  1. An inquiry moves fastest when it has a reference link.
  2. Replies come within about an hour during business hours, with scope explained against the 'workings that attach' table.
  3. To begin: if you hand it over, we agree the schedule first; if you build it yourself, the founder is hands-on for the setup.

The makers

The Saeroon founder and team handle everything from build to operations. From your first inquiry to the wiring, the person whose hands are actually on it answers you.

There's one point of contact. The person who takes your inquiry is the one who builds and runs it. And you can mix the two ways site by site.

Operating terms
  • No lock-in. Assets leave freely, cancellation has a 30-day grace period, and deployed files are standard HTML originals.
  • Prices fixed for 12 months · 60 days' notice before any change
  • The site footer carries one line — 'Powered by Saeroon Hosting'; reports and billing carry your agency's brand
  • Support is docs and MCP first; email and text get business-day responses
  • Customer-impacting incidents are logged. Urgent operational issues go through the same channel
Pilot — 3–5 agencies

It's for agencies with their own build pipeline. The trial is the standard way in; the pilot is a track where setup comes bundled, for the first 3–5 to sign up. Three months base-fee free (the 1% sales fee still applies), then 12 months at −30% (off list price), with white label free for good (first 5 only). After converting to a regular plan you move onto the standard support channels, and we ask for monthly feedback and consent to feature the work (your logo).

  • Replies usually within an hour during business hours
  • Scope follows the 'workings that attach' table
  • Onboarding is run by the founder directly
