Your storefront, built visually, owned by you
A no-code builder that does not feel like a template. Real brand control, real live preview, real custom domain, real performance.
Most no-code storefront builders trap you inside templates that all look the same. You change a color, swap a logo, and the site still reads as generic. Customers see the template before they see the brand. By month six, you are paying a developer to override the template anyway, defeating the point of buying a no-code tool.
Mercemur takes a different approach. The builder is section-based, not template-based. Start with five page templates (Home, Shop, Blog, About, Contact) and a library of 18 pre-built section types. Arrange them. Theme them. Add content slots wherever the default layout falls short. Preview every change live at four widths before publishing.
The result looks like a brand site, not a template. The same builder powers a luxury fashion DTC store, a software vendor selling license keys, a multi-brand operator running ten storefronts, and a B2B catalog with authenticated pricing. None of them look the same.
What you can build
Section types available in the builder:
Hero sections
- Full-bleed hero with overlay copy and CTA
- Split-layout hero with image on one side, copy on the other
- Video-backed hero for high-energy brands
- Minimal hero for editorial brands
Promotional surfaces
- Promo banner pinned to the top of the page
- Deals countdown for time-sensitive offers
- CTA banner pinned to a scroll position
- Banner grid for multi-message merchandising
Product surfaces
- Product tabs (new arrivals, best sellers, on sale)
- Best sellers grid
- Small products grid for tight layouts
- Featured grid for editorial product features
- Collection carousel for category-style discovery
- Collection grid for grid-style category landing
Category surfaces
- Category bubbles for visual category navigation
- Brand story panels for editorial brand-building content
Trust and social proof
- Quote banner for press mentions or founder quotes
- Testimonials slider for customer voice
- Value props row (three or four trust signals in a horizontal layout)
Content surfaces
- Blog preview (latest 3 to 6 articles)
- Custom HTML blocks for anything not covered by the section library
Every section type accepts its own configuration: copy, images, button labels, links, alignment, padding. Drag a section in, configure it in the side panel, see it render in the preview.
Themeable from one panel
Brand control without code. The global config panel covers:
Change a color, the storefront re-renders against the new token everywhere it appears. No find-and-replace, no CSS to maintain, no production deploy. Brands that rebrand mid-year change a few values and move on with their day.
Live preview at four widths
Side-by-side live preview with four viewport modes:
Mobile
for the customer who finds you on Instagram and adds to cart from a phone
Tablet
for the long-tail iPad shopper
Desktop
for the typical seated browsing session
Fluid
for ultra-wide displays and unusual aspect ratios
What you see in the preview is what your customers see in production. Test the mobile experience without picking up a phone. Catch layout breaks before they ship. Adjust spacing for tablet without compromising desktop. The preview is real rendering, not a screenshot, so dynamic content (product grids, cart totals, search results) all behave correctly.
Per-page content slots
The builder supports custom content slots at specific positions on the storefront:
Product page
Above main:
trust badges, size guide, shipping promise, free-shipping threshold callout
Below main:
return policy, FAQ section, related-products module, cross-sell recommendations
Collection page
Above grid:
seasonal banner, category description, filter helper
Below grid:
long-form SEO content, related collections, brand-story link
Cart page
Above cart:
free-shipping threshold meter, upsell module, gift-wrapping prompt
Below cart:
guarantees, refund promise, payment-method icons
Empty state:
guidance for first-time visitors, popular products, signup prompt
About page
Body:
founder story, brand timeline, custom content, press mentions
Slots persist across page edits, so seasonal swaps (new free-shipping threshold, new featured collection) take seconds.
Custom CMS pages
Build any page you need with its own slug, title, SEO title, SEO description, and published state. Use them for:
Every CMS page goes through the same visual builder as the storefront. The same section types are available. SEO meta is configurable per page.
Multi-language storefront
Ship your store in multiple languages from the same admin. Country-based routing means customers see content and pricing in their region's locale. Each language gets its own SEO meta and its own URL structure for SEO. Add a new language without rebuilding pages, the section structure carries over.
Storefront full-text search
A built-in product search index that returns results as the customer types. Customers search by product name, variant, or category. No third-party search service to wire up, no monthly bill, no schema syncing. Search results respect price list and region settings, so a customer in India sees INR prices on results.
Pre-launch and coming-soon mode
Every store has a status: active, coming soon, suspended, or pending. Coming-soon mode lets you finish setup with the storefront behind a wall while still collecting email signups. The wall is real (uninvited visitors do not see the storefront), the signup form is real (collected addresses become a Resend audience), the flip to public is one toggle.
Store locator
A customer-facing locations page lists every physical retail location. Each location shows: Address (street, city, state, country, postal code), Phone, Email, Hours of operation, Map coordinates (lat/long for the embedded map), Active flag (so you can hide a temporarily-closed location). Useful for omnichannel brands that pair an online store with physical retail.
Shareable preview links
Generate a private preview link from the admin to share an in-progress storefront with collaborators, investors, advisors, or PR partners before launch. The link respects the coming-soon wall but lets your invited guests through. Revoke the link any time.
Built for the people who actually use it
The builder is built for merchants, marketers, and brand managers, not developers. The terminology in the builder uses words a merchant uses: "hero", "promo banner", "featured products", "testimonials". Not words a developer uses ("component", "render", "props"). You should never have to ask what a label means.

Use cases
Fashion DTC brand
Hero with seasonal lookbook, category bubbles for shop-by-occasion navigation, featured grid showcasing the hero collection, brand-story panel, testimonials slider, blog preview. Custom slot on product page for size guide and free-shipping promise. Custom CMS pages for the sustainability story and the founder's note.

Multi-brand operator
Each brand gets its own storefront with its own custom domain, its own theme, its own content slots. Brand A is a luxury watch retailer with editorial-style sections. Brand B is a casual sneaker brand with grid-heavy merchandising. Both run from the same admin under one billing relationship.
B2B catalog
Authenticated storefront with collection grids gated by customer group. Wholesale customers see their pricing. Retail visitors see the public landing page. Custom slot on product page for bulk-order request form. Custom CMS pages for the line sheet, lookbook, and rep contact information.
Subscription box business
Hero pushing the box subscription, product tabs showing past boxes, testimonials slider, FAQ as a CMS page, blog preview with unboxing content. Custom slot on cart page for the recurring-billing explanation.
Local boutique with online and retail
Storefront for online orders, store locator page for the physical retail location, blog for in-store events and new arrivals. Custom slot on collection page for the 'shop in store' pickup option.
Best practices for the storefront builder
Start with the hero, end with the CTA banner
The hero sets the brand promise. The CTA banner reinforces it on the way out. Everything in between supports one or the other.
Use category bubbles for visual browsing
Customers shop by occasion or season, not by SKU. Category bubbles let them browse without reading.
Add a brand-story panel on the homepage
Customers want to know who they are buying from. A short brand-story section converts first-time visitors at a higher rate.
Use page slots for conversion-rate optimization
Trust badges above the product page. Return policy below the cart. Free-shipping threshold meter at the top of the cart. Each slot is a chance to remove an objection.
Build legal pages as CMS pages, not third-party links
Privacy policy and terms of service should live on your domain, not link out. CMS pages keep the customer in the brand experience.
Update the OG image per product
The Open Graph image is what shows when customers share your product on social or messaging apps. A generic image hurts your share rate.
Common pitfalls
Too many sections on the homepage
A homepage with 15 sections is a homepage that does not load fast. Pick the four or five sections that matter most.
Inconsistent spacing between sections
The builder lets you control padding per section. Use it. Consistent vertical rhythm makes the page feel designed, not assembled.
Ignoring mobile until launch
The live preview at 375px width tells you what mobile customers see. Check it as you build, not after.
Forgetting the favicon
The favicon shows in browser tabs, bookmarks, and search results. A missing favicon makes the store look unfinished.
Skipping the SEO meta
Every page has SEO meta fields. Fill them in. The default title and description from the storefront name are not enough.
