Stilmerce Core

We redrew the boundaries.

Stilmerce Core is not a theme or a demo store. It's the same production-grade codebase that also powers our full multi-vendor marketplace edition — running here with the marketplace plugins switched off. Next.js 15, NestJS 11, PostgreSQL and Redis, from day one.

The Flagship

Not a template. A platform.

Every line was written to run a real store under real traffic — not to look good in a demo.

Rendering

RSC

Next.js 15 App Router

Deployment

Docker

Container-first architecture

Password hashing

Argon2

Native Rust binding

Core Capabilities

Four pillars, one core.

Storefront

Rendered with Next.js Server Components — fast, SEO-friendly, no template bloat.

Admin

Catalog, orders, accounting and staff permissions — one command center.

Payments

Stripe, PayPal, iyzico and PayTR — a real, multi-provider payment layer.

Plugins

A real plugin SDK, activated without touching the core.

Under the Hood

A stack built to be read, not just run.

Front, Admin and API are three independent Next.js/NestJS applications sharing one codebase and one contract. Domain events run through a transactional outbox — the same pattern banks use so a state change and the event announcing it can never drift apart — and outbound webhooks are signed with HMAC-SHA256, Stripe-style, so receivers can verify a payload actually came from you.

Checkout Engine

The last unit in stock never sells twice.

Two shoppers, one last unit, at the same second. Most storefronts oversell this. Stilmerce Core doesn't.

Operations

Not an admin panel. A command center.

Over a hundred screens, organized so a real operator — not a developer — runs the store day to day: catalog, orders, marketing, staff, and a full accounting back office, all from one interface.

One console, every part of the business.

Take the Tour

Products, variants and a real search engine. Products, categories, attributes, brands and collections — plus Typesense-backed search and a configurable recommendation engine (best-sellers, related products, editor picks, new arrivals) that admins tune without touching code. Bulk import/export runs on Excel/CSV.
From checkout to return, one clean trail. Order management with returns/RMA handling and admin-configurable return reasons, a full inventory-history audit trail, and low-stock views so nothing runs out silently.
The books, built in — not bolted on. P&L (cash and accrual), VAT reports, an auto-generated general ledger, bank transaction import with reconciliation, multi-currency reporting, e-invoice status tracking, and a unified payout ledger. Export anything to CSV.
Segments, loyalty and campaigns that talk to each other. Customer segments, a loyalty points + wallet system, coupons, flash deals, dynamic popups, SMS/email campaigns and broadcast tools — plus analytics dashboards to see what's actually working.
Permissions that can never drift out of sync. The permission list isn't hand-maintained — it's derived automatically from the real API at boot, so every new endpoint gets a matching permission without anyone remembering to add one. Every admin action is written to an audit log you can review.
Grow into multi-vendor without a rewrite. Core ships with the marketplace plugins switched off, not removed. When you're ready, activating Multi-Vendor and Vendor Plans turns this exact installation into a full marketplace — same database, same admin, same storefront.

Products, variants and a real search engine. Products, categories, attributes, brands and collections — plus Typesense-backed search and a configurable recommendation engine (best-sellers, related products, editor picks, new arrivals) that admins tune without touching code. Bulk import/export runs on Excel/CSV.

Finance

Stop exporting to your accountant's spreadsheet.

Most platforms hand you order totals and wish you luck. Stilmerce Core gives you an actual back office.

Access Control

Your permission list can't lie to you.

Most platforms' "roles & permissions" screen is a checkbox list someone forgot to update. Ours can't fall behind.

Payments

Built for Turkey and the region, not bolted onto it.

Stripe and PayPal for global reach, plus native iyzico (with its own 3-D Secure verification flow) and PayTR — the gateways most Western platforms make you build yourself. All four route through one provider registry, so adding a fifth gateway later never touches your checkout logic.

Discovery

Search that understands products, not just strings.

Typesense-backed search, plus a recommendation engine and AI-assisted content tools your team actually controls.

Security

Security that's actually in the code, not just the pitch deck.

Two-factor auth built from scratch, correctly. Rate limiting that can't be spoofed by a fake header. An audit trail for every privileged action.

Grow On Your Terms

Start single-vendor. Stay ready for more.

Core isn't a stripped-down trial of "the real product." It's the real product, with a switch left off.

Customer Experience

A storefront customers actually want to come back to.

A real customer dashboard — orders, tracking, returns, digital downloads, loyalty points and wallet, saved payment methods, an affiliate portal, notifications — plus wishlists, recently-viewed, moderated reviews with vendor replies, and product Q&A. Three languages ship today, including Arabic, so right-to-left isn't an afterthought.

Frequently Asked Questions

Does the core ship as single-vendor?

Yes. The core is a fast and lean single-vendor commerce foundation; marketplace features are unlocked through the Multi-Vendor plugin.

Is full source code included?

Yes. Next.js storefront, NestJS API, Admin dashboard, customer portal, TypeORM migrations, and installer scripts are 100% included in full TypeScript source code.

Are accounting and multi-currency modules included?

Yes. As of version 1.2.0, double-entry journal ledgers, bank reconciliation, GİB e-invoice records, and dynamic currency conversion are built right into the core.

How are software updates delivered?

Releases are published through Stilgen Hub with SHA-256 checksums, digital signatures, and release notes. Your customer portal displays eligible updates automatically.

How easily can we brand and adapt it to our business?

Brand colors, logos, domains, media storage (S3/R2), payment gateways, and legal terms are configured via the admin panel or environment files without touching code.

Are there monthly GMV revenue shares or hidden fees?

Absolutely zero. You host on your own servers; Stilgen takes 0% commission regardless of how large your revenue grows.
