Buyers design a shape, fit it to their room and ask local makers for a price; makers pay a flat listing fee, no commission. Its 564 pages are pre-rendered, so crawler compute fell from 103 Worker calls to 0 in a 45-second sample.

Expensive for bots. The first version rendered pages on request inside a Cloudflare Worker. People never noticed. Crawlers did: they walk every shape, every sofa and every seller page, and each visit woke the Worker and burned compute. For a marketplace that wants to be found by search engines and AI assistants, that bill grows with exactly the traffic you want more of. Crawler sample · 45 seconds 2026-10-01 **pages** risk: Shape, sofa and seller pages, rendered on request **before** problem: 103 Worker invocations from crawlers in 45 seconds **cost curve** problem: More crawling meant more compute, linearly **the fix** note: Pre-render all 564 pages at deploy time, in 3 languages **after** fine: 0 Worker invocations in the same 45-second sample *Method: live sample of crawler requests before and after the static rebuild.* *Form · GET /audit/ · fields: Your website address · button: “Scan my site →”* **Does your site make crawlers wait for a server?

Teal is the machine at work. Custom sofas are bought by eye and often arrive wrong, and small workshops can’t pay for photo shoots or marketplace commissions. So SitShape draws every sofa from a list of modules: no photography needed. Buyers start from 155 shapes in 8 families, fit one to their actual floor, and only then ask makers for a real price. 1. Step 1 (buyer): Design a shape, 155 shapes, 8 families. 2. Step 2 (automated): Shape Finder, fits the real room. Rejected here: Paid ranking (refused: fit ranks first). 3. Step 3 (buyer): Ask chosen makers, anonymous until then. 4. Step 4 (automated): Seller portal, magic link, no password. 5. Step 5 (maker): Maker quotes, direct to the buyer. 6. Step 6 (live): Static storefront, 564 pages, 3 languages. *FIG 02 — How a SitShape request flows Every gold step is a person deciding. Makers pay to be listed, never to be ranked: the finder sorts by fit, lead time and responsiveness.* ![SitShape home page on desktop: “What shape do you sit in?” beside an isometric drawing of a curved sofa](https://webrevolution.si/_astro/sitshape-desktop.DhzKGA7D_Z1jo54L.png) ![SitShape home page on a phone with the Build a shape button](https://webrevolution.si/_astro/sitshape-mobile.enNu-r20_fdbSa.png) *PLATE 01 — sitshape.com home, desktop and phone · live product, captured 2026-10-05* ![SitShape builder: a straight sofa drawn inside a room outline, with “Ask for a real price”](https://webrevolution.si/_astro/sitshape-build-desktop.Cej6ib0t_1Ekldb.png) ![SitShape seller page: “You sell sofas.

A human approves. 1. agent://researcher Sized the market of independent sofa makers and how they win and lose work today. **Never allowed to:** set the price model. 2. human://vegard HUMAN GATE Chose the model: a flat listing fee by territory, zero commission, and a trial that ends at the first lead. 3. agent://architect Designed the module language that turns a list of pieces into a drawing, so no product photography is ever needed. 4. agent://builder Built the configurator, the Shape Finder, the vendor portal and a static build that renders all 564 pages in 3 languages. 5. agent://tester Runs 559 automated tests on every change, before anything ships. **Never allowed to:** mark a failing check as passed. 6. human://user HUMAN GATE A buyer decides which makers see the request. Until then, nobody gets their details. 7. agent://watcher Runs the daily housekeeping for trials and leads; the admin console shows funnel, demand, sellers and requests. **Never allowed to:** share a buyer’s details without consent. 04 · Results ## Results, with receipts Every number dated, with its method. *SitShape: results with method and date* | Number | What it measures | How it was measured | Observed | | --- | --- | --- | --- | | 103 → 0✓ verified | Worker invocations from crawlers in a 45-second sample, after the static rebuild | live sample | 2026-10-01 | | 564✓ verified | pre-rendered pages in 3 languages | build output | 2026-10-01 | | 559✓ verified | automated tests | test suite count | 2026-10-05 | | 155✓ verified | sofa shapes in 8 families | catalogue | 2026-10-05 | | $79–$349/mo✓ verified | flat seller listing plans by territory (Local, Regional, National), zero commission | pricing config | 2026-10-05 | | Not measured yet | Seller sign-ups and buyer requests | early days; published once there is a quarter of data | — | 05 · Running costs ## What it costs to run The storefront is static files served from Cloudflare’s edge, so a crawler reading every page costs nothing in compute. The Worker only runs for the parts that need a server: buyer requests, the seller portal, payments. Stripe runs on Stripe’s own hosted pages, which keeps tracking scripts off the site and the no-cookie promise intact. One database, one daily cron, one email binding. 06 · Ownership ## What you would own If I built this for your business. - **The code and the build** The configurator, the static build and the portal, in your repository. - **Your Cloudflare account** Workers, static assets, database and email, under your name. - **Your Stripe account** Plans, trials and the customer portal, all billed to you directly. - **The product language** The module system that draws your products, documented. - **The test suite** Every pricing, consent and storefront rule, tested. - **The admin console** Funnel, demand, sellers, requests and emails in one place. 07 · What I’d build for you ## A configurator or quote tool that sells, and costs almost nothing to serve If you sell something configurable, from furniture and machinery to service packages, I’ll build the configurator or quote tool that lets buyers design it, see it, and ask for a price, on a static architecture that costs next to nothing to serve and that AI assistants can read in full. - Visual configurator or quote builder, drawn from your product data - Lead capture or Stripe checkout, on your own accounts - Pre-rendered pages that search engines and AI crawlers read for free - Optional MCP endpoint so AI agents can use your tool **Not for you if** your product can’t be described by rules. I build tools on real logic, not guesses.
