Autonomous Commerce Agent
Think of this as your 24/7 e-commerce operations manager. This intelligent agent doesn't just set up your store; it orchestrates the entire backend stack.

Frequently Asked Questions
Shack FAQ
How do I sign up for Shack?
Signing up is designed for maximum speed and security. You can easily create an account using Apple Sign-In directly within the iOS app, ensuring a seamless and private onboarding experience without the need for lengthy forms.
Are there any transaction or seller fees?
No. Shack operates on a groundbreaking 100% fee-free model. Buying and selling is completely free of charge. There are never any commission fees or transaction costs deducted from your sales, which is a major disruption in the C2C marketplace space.
What payment methods are supported?
Transactions are flexible and peer-to-peer. Buyers can pay sellers in CHF via TWINT, in EUR, via PayPal, or even with cryptocurrency if the seller chooses to offer it. This puts the payment choice directly in the hands of the users involved in the transaction.
What devices are supported?
Currently, Shack is available exclusively as a native iOS application. You need an iPhone or iPad running iOS 17.0 or later to download the app from the App Store and start buying and selling.
Stable Commerce FAQ
How does the "prompt-to-store" feature actually work?
You provide a natural language description of what you want to sell (e.g., "an online store selling eco-friendly yoga mats and accessories"). Stable Commerce's AI interprets this prompt, selects an appropriate design theme, structures product categories, sets up essential pages (Home, About, Contact), and pre-configures core settings like taxes and shipping regions. You then import your specific products to populate this generated framework.
What does the Autonomous Agent do on an ongoing basis?
After launch, the agent operates continuously in the background. It monitors store performance and sales data, manages inventory sync across channels, ensures all connected services (payments, analytics, fulfillment) are running smoothly, and executes automated optimization routines. This can include tweaking site elements for better conversion, generating performance reports, and alerting you to significant trends or issues.
Can I connect my own custom domain?
Yes. While the Free plan provides a Stable Commerce subdomain, the Basic plan and above include the ability to connect one or more custom domains (e.g., www.yourbrand.com). This is a standard feature for establishing a professional brand identity and is integrated seamlessly through the platform's settings.
What is the "success fee" mentioned in the pricing?
Stable Commerce employs a hybrid pricing model. On top of any monthly subscription fee, a small percentage (the success fee) is applied to your sales revenue. This aligns the platform's incentives with your growth; they succeed only when you do. The fee decreases as you move to higher-tier plans (e.g., from 3% on Free to 0.5% on Pro), rewarding scale with better rates.
Alternatives
Shack Alternatives
Shack is an AI-native, fee-free auction app revolutionizing the C2C marketplace in the DACH region. It belongs to the fast-evolving category of hyper-local, tech-driven platforms that prioritize authentic, second-hand commerce and sustainable consumption. Users often explore alternatives for various reasons, including different geographic availability, specific feature sets like advanced seller tools or broader item categories, and varying platform policies on fees or verification processes.

Stable Commerce Alternatives
Stable Commerce is an AI-native eCommerce and automation platform designed to launch and manage online stores with unprecedented speed. It promises to handle everything from initial setup to ongoing optimization, making it a compelling choice for entrepreneurs seeking a frictionless start. Users often explore alternatives for several key reasons. Pricing structures and specific feature needs, like advanced inventory management or deeper platform integrations, can drive the search. Some businesses may require more granular control over their store's design or backend processes than an ultra-automated solution provides, while others might prioritize established ecosystems with vast app marketplaces. When evaluating other platforms, focus on the core trade-off between automation and control. Consider the total cost of ownership, including transaction fees and any required add-ons. Scalability is crucial—will the platform grow with your sales volume and complexity? Finally, assess the learning curve and the quality of support, as these factors significantly impact long-term operational efficiency.
