Features and specs

What each product offers, as listed by its team.

StackBlitz 6 features
OptiDress.fr 4 features
  • Speed
    StackBlitz is known for its quick load times and fast editing capabilities, making it ideal for rapid development and testing.
  • Ease of Use
    The interface is intuitive and user-friendly, allowing developers to get started quickly without a steep learning curve.
  • Zero-Setup
    Users can write, compile, and run code directly in the browser without any setup or configuration required.
  • Integrations
    StackBlitz integrates seamlessly with GitHub, allowing for easy import and export of repositories.
  • WebContainers
    StackBlitz uses WebContainers to run Node.js applications in the browser, providing a near-native development experience.
  • Collaboration
    Real-time collaboration features allow multiple users to work on the same project simultaneously, similar to Google Docs.

Possible disadvantages

  • Limited Plugins
    Unlike traditional IDEs like VSCode or IntelliJ, StackBlitz has a limited ecosystem of plugins and extensions.
  • Online Dependency
    StackBlitz requires an internet connection to function, which can be a limitation for developers who need to work offline.
  • Performance
    For very large projects or those requiring extensive computational resources, performance may degrade compared to local development environments.
  • Mobile Accessibility
    While StackBlitz is accessible on mobile devices, the user experience is not as optimized as it is on desktop browsers.
  • Limited Framework Support
    Although StackBlitz supports many popular frameworks, it doesn't support all frameworks or versions, which could be limiting for some projects.
  • Storage and Persistence
    Files and data are stored in the cloud, which might raise concerns around data privacy and persistence for some users.
  • Virtual Fitting Room
    Shoppers enter their height, weight and body shape, no photo, ever. Their 3D digital twin is generated in seconds, and they see the garment worn on their own body. Where most solutions lose the shoppers who won't photograph themselves mid-purchase, OptiDress keeps them.
  • Native size recommendation
    For every product, the size to order is displayed along with a fit description, calculated from the shopper's body data and the garment's real measurements, cut, dimensions, fabric. Not a size chart sitting next to a render: the same profile drives both the visual and the sizing.
  • Avatar saved for 30 days
    Returning shoppers find their digital twin waiting and try garments on straight away. Fashion purchases rarely happen in a single visit — without persistence, the shopper starts over every time and eventually gives up.
  • Self-serve on Shopify, assisted setup elsewhere
    On Shopify, OptiDress installs from the App Store as a native app and you set it up yourself. On WooCommerce it ships as a WordPress plugin, and on any other store as a universal script — there, the OptiDress team handles installation and configuration. No theme rebuild and no new product photography: the widget appears on your product pages in your brand colours, prepared from your existing visuals and your garments' real data.

Questions & Answers

As answered by people managing StackBlitz and OptiDress.fr.

Why should a person choose your product over its competitors?

OptiDress.fr's answer:

Three reasons, in order of what they change for a store.

No photo means no lost shoppers. A share of visitors will not photograph themselves at the point of purchase, and every photo-based tool loses them silently.

Fit and appearance in one product. Sizing isn't a second tool to buy and connect it runs on the same profile, per product, with a fit description.

Nothing to build. The OptiDress team handles installation and configuration in under 24 hours, across Shopify, WooCommerce, Magento, PrestaShop, BigCommerce, Wix, Squarespace, Webflow, Shopware, Salesforce and custom builds. No theme rebuild, no new product photography, no development work.

Pricing scales with monthly store traffic rather than render counts, with no commitment which keeps it accessible to independent brands rather than enterprise budgets.

What's the story behind your product?

OptiDress.fr's answer:

OptiDress was founded in 2026 in Paris by Arthur Renard and Raphaël Zafran.

The starting point was a gap in how virtual try-on had been built. Tools either showed garments on generic models, useful for presentation, useless for fit, or generated an image from a photo the shopper uploaded, which excludes everyone unwilling to photograph themselves and still can't say which size to order. Sizing was sold as a separate product, by separate vendors.

The choice was to build from declared body data instead of images: one profile that drives both what the shopper sees and the size they should order, with no photo at any stage. And to make it accessible to independent brands, not just retailers who can absorb an enterprise contract.

What makes your product unique?

OptiDress.fr's answer:

OptiDress is the only virtual fitting room where neither the avatar nor the try-on requires a photo. Shoppers enter their height, weight, body shape and optional measurements, a 3D digital twin is generated from that data alone. Because the system holds real body data rather than an image, the same profile also powers a per-product size recommendation with a fit description, calculated against each garment's real measurements, cut and fabric. Most tools answer how a garment looks; a photo carries no measurements, so they can't tell shoppers which size to order. The avatar is saved on the store for 30 days, so returning shoppers don't start over.

How would you describe the primary audience of your product?

OptiDress.fr's answer:

Independent fashion brands and e-commerce retailers selling apparel online, primarily on Shopify. Typically direct-to-consumer brands where the founder or e-commerce lead makes the decision, companies feeling the cost of size-related returns and abandoned carts, but without the budget or team for an enterprise deployment. Currently focused on Western Europe, the UK and the US.

Which are the primary technologies used for building your product?

OptiDress.fr's answer:

Web-based SaaS. Front-end widget embedded on merchant product pages, back-end services handling avatar generation and size computation. AI-powered garment rendering. Integrations through native apps and plugins across major e-commerce platforms, plus API access for custom builds. EU-hosted.

Who are some of the biggest customers of your product?

OptiDress.fr's answer:

OptiDress currently works with a selected group of independent fashion brands in Europe. Customer names are not published at this stage.
