Behind Cartly.

An ecommerce platform is the software that runs your online store: catalog, storefront, checkout, and payments in one system. This guide covers how SaaS, open-source, and headless platforms differ, what to look for in 2026, and where Cartly fits.

Connect your Google Analytics 4 property and Cartly brings your traffic, channels, and top landing pages right into your analytics dashboard — a clearly-labeled second lens beside your own orders and funnel. It pairs naturally with Agent Commerce, which makes your catalog readable by AI shopping agents.

Atrium is a new furniture and interior theme for the Cartly Theme Store. Every product leads with its measurements — a dimension strip on each card, a 1:20 plan view on the product page, and filters for width, seat height, material and lead time — so shoppers can plan the room before it arrives.

AI shopping agents are becoming a real sales channel — shoppers now ask an assistant to find, compare, and buy for them. Cartly stores are agent-ready out of the box: a machine-readable discovery manifest, rich Product structured data, and an anonymous, market-aware catalog API that lets agents browse your products, prices, and availability. You stay in full control with a one-click opt-out.

Let your business customers sign in with your company identity provider, build product variants faster with bulk edits and drag-to-reorder, personalize the cart with custom fields and free samples, and launch the new Balm storefront theme for skincare and beauty.

Cartly now connects with the email and SMS marketing tools you already use — Klaviyo, Mailchimp, Brevo, Omnisend, and Bird — and imports your Judge.me product reviews straight onto your storefront.

Accept global card payments and Buy Now, Pay Later at checkout, quote live carrier rates and print labels, and keep shoppers updated with automated order tracking.

The Cartly admin panel now works in six languages — English, German, Spanish, French, Ukrainian, and Russian — and a wave of security hardening protects merchant logins, password resets, and customer accounts at checkout.

This release adds a new eBay sales channel, native QuickBooks Online, Xero, and Salesforce connectors, first-party SendGrid and Twilio apps for order messaging, and hardened payments that settle directly to your own Stripe account.

This release adds two-way order sync with your connected ERP or accounting system, upgrades Abandoned Cart Recovery to a 3-step email drip with a real discount incentive, and gives the Clarity, Linen, and Mono themes a systemic design refresh.

This release brings pickup-point and parcel-locker delivery at checkout, one-click shipment creation with printable waybills, a redesigned Orders workspace with global search, and a storefront market selector for cross-border, multi-currency selling.

A rebuilt Options Builder for product variants, per-variant cost (COGS) tracking, better multi-option storefront rendering, and advanced catalog sync with external ERP and inventory systems.

Social login for store admins (Google & GitHub), AI provider fallback with semantic cache, in-store support tickets via Command, and smarter onboarding for new stores.

The Metaobjects admin is now a real CMS: Tiptap WYSIWYG, media/reference pickers, array fields, choices validations, drag-to-reorder, bulk actions, JSON view, Storefront usage scanner, and JSON/CSV export. The Visual Editor gains a Section Blocks accordion for live block editing with iframe highlight.

Two clear surfaces for merchant scripts: site-wide head/body injection for GTM and chat widgets, and order-confirmation scripts for Google Ads, Facebook Pixel, and TikTok purchase events. CSP nonces injected automatically.

Cartly Markets lets you run one shop across many countries — per-market currency, language, VAT/sales-tax mode, and duty handling, with automatic GeoIP routing and a strict Primary Market guarantee.

Cartly now shows prices in any currency with automatic live exchange rates from OpenExchangeRates, per-currency markup, configurable rounding, and zero-decimal currency support — no third-party app required.

v1.19: customer account pages now themeable in all 7 marketplace themes, team invitations, multi-currency store credit, and customer-facing return requests.

Clarity, our new editorial marketplace theme, joins the Cartly AppStore as the default for new shops — filter-rail PLP, sticky PDP, bundle + reviews + recently-viewed sections, AJAX Quick-Add, and full i18n across 7 locales.

Collection pages now have sidebar filters powered by Typesense — auto-detected from your product data, configurable from Settings, and extensible with custom metafield filters. No theme changes required.

The Cartly admin panel has been rebuilt with a dark-first design system, 375px mobile layout, and a systematic accessibility sweep. Every page, every route — updated.

Browse and install apps, themes, and integrations from the new Cartly App Store — an open marketplace for extending your online store.

Theme code now lives in the platform by default — your customizations stay yours, and platform updates flow in for everything else. Plus a new Monaco diff editor, fork-confirmation flow, upstream-update banner, and a Preview button.
