TL;DR: Greta.sh vs Shopify is a build-versus-rent choice. Shopify rents you a hosted storefront with a monthly plan, payment fees, and a platform-defined feature set extended by apps. Greta.sh lets you build a custom commerce app from prompts, with ownable code and full control over logic. Shopify suits standard stores; Greta.sh suits unique commerce models.
Introduction
Shopify made launching a store easy, and "easy" comes with rent: monthly fees, payment fees, and a feature set defined by the platform and its apps. For founders with unusual commerce needs, that trade is worth weighing.
This guide compares Greta.sh vs Shopify as a build-versus-rent decision, covering ownership, fees, flexibility, and when each genuinely makes sense in 2026.
What is Shopify?
Shopify is a hosted commerce platform that lets you set up an online store from a prompt or a pre-built template, with a product catalog, checkout, a built-in AI assistant (Sidekick), and thousands of app integrations. You pay a monthly subscription plus card fees, and a third-party transaction fee when you use a payment provider other than Shopify Payments.
It's excellent for standard retail: you configure rather than build. The trade-offs are recurring costs and customization within the platform: extra features often come from apps, and checkout customization is limited on plans below Plus.
What does building with Greta.sh look like?
Greta.sh is an AI vibe-coding platform that builds custom web apps --- including commerce apps --- from natural-language prompts, producing an ownable codebase rather than a rented storefront.
Instead of fitting your business into a template, you describe the exact commerce model you need and Greta.sh generates it. That's powerful when your model isn't a standard store.

Greta.sh vs Shopify: Build vs Rent
The table frames the decision as ownership and control versus convenience and recurring cost.
| Factor | Shopify (rent) | Greta.sh (build) |
|---|---|---|
| Setup speed | Very fast, template or prompt | Fast via prompts |
| Ongoing cost | Monthly plan + payment fees | Hosting + your time |
| Customization | Themes + apps | Full custom logic |
| Code ownership | Platform-hosted | Own & export code |
| Unusual models | Within platform features and apps | Built to your spec |
| Best for | Standard retail stores | Custom commerce models |
When should you just use Shopify?
Use Shopify when you're running a fairly standard store --- physical or digital products, normal checkout, typical shipping. The platform handles payments, taxes, and logistics integrations out of the box.
If speed to a conventional storefront matters more than owning custom logic, renting is the pragmatic call.

When does building a custom commerce app win?
Building wins when your commerce model is unusual --- complex subscriptions, marketplace mechanics, custom pricing, or bundled services a template can't express. Owning the code means the logic is yours to change and export.
It also wins on long-term flexibility. For service-style commerce, the structure of a freelancer portfolio with a client portal shows how custom flows come together. For a database-first comparison, see Greta.sh vs Softr.

Common Mistakes to Avoid
- Forcing an unusual commerce model into a standard store template.
- Ignoring cumulative transaction fees when comparing long-term cost.
- Building custom when a standard store would have shipped faster.
- Underestimating payment, tax, and shipping complexity in a custom build.
- Launching a custom checkout without a thorough security review.
Frequently Asked Questions
Q1: Is Greta.sh a Shopify alternative?
For custom or unusual commerce models, yes --- Greta.sh builds an ownable app. For standard retail stores, Shopify's out-of-box tooling is hard to beat.
Q2: Why build instead of rent a store?
To own your code, rely less on add-on apps, and support commerce logic a template can't express. It's about control and flexibility.
Q3: Does Shopify charge transaction fees?
If you use a third-party payment provider instead of Shopify Payments, every Shopify plan adds a transaction fee, from 2% on Basic down to 0.2% on Plus (as of October 2026). Card processing fees also vary by plan. Factor these into long-term cost comparisons.
Q4: Can a custom app handle payments and taxes?
Yes, via integrations like Stripe and tax services --- but you're responsible for wiring and reviewing them. A standard store handles more by default.
Q5: Which is cheaper over time?
It depends on volume. High-volume or unusual stores may save by building; standard stores often find renting simpler and cheaper to start.
