    Outgrowing Vajro?
    A Smarter Shopify App for the Next Stage

    Vajro is cheap and easy to start. The trouble starts when your loyalty program needs to understand a customer, when push campaigns need to segment by behavior, or when a billing edge case ships a partially paid order. Fastshot generates real native code for your retention app — and the logic does what you tell it to.

    Beyond the Template: What Changes When the App Is Code

    Vajro made the right call on price. It is one of the cheapest reliable ways to get a basic Shopify catalog app on iOS and Android without an agency. For a brand testing whether the app channel earns its place at all, that low price floor is a defensible starting point.

    The split usually happens later. Vajro's builder is a template — fast to configure, but bounded by what the templates support. The more retention-specific your app needs to get (a tiered loyalty engine that reads Shopify customer metafields, a drop waitlist that throttles by VIP tier, a reorder flow that adapts to last-order date), the more you find yourself filing feature requests instead of shipping. Vajro users on r/shopify have flagged real billing reliability issues too — partial payments arriving without warning is the kind of thing that turns a 'cheap and easy' decision expensive.

    Fastshot is built for the second half of that journey. Describe the retention behavior — push drops, VIP early access, one-tap reorder, post-purchase upsell — and Fastshot generates the React Native code that delivers it. You own the source, you tune the logic, and the Shopify integration is wired to your checkout directly, not abstracted behind a builder you do not control.

    Where Cheap Still Wins

    Vajro earns its place at the low end. A small Shopify store testing whether an app channel exists at all does not need source code or custom loyalty logic — it needs a working catalog app it can afford. That is exactly the brief Vajro built itself around, and the price floor is hard to beat. The case for Fastshot starts later: when the retention motion outgrows what the template supports, or when one billing reliability bug — the partial-payment edge case users have surfaced on r/shopify — is enough to make the cheaper path the more expensive one.

    Common Questions About Switching from Vajro

    Is Fastshot more expensive than Vajro?

    No. Vajro starts well below $100/month for basic plans; Fastshot is free to build and publish with your own App Store and Google Play accounts, and White Glove starts with a call. They still target different stages — Vajro is the cheap way to put a catalog app on the stores, Fastshot is what you move to when the catalog app is no longer the bottleneck and you need custom retention logic that the template cannot express. If you are happy with a Vajro-shaped app, Fastshot is overkill. If you have outgrown it, the template is what holds you back, not the price.

    Can Fastshot handle the same Shopify integration features as Vajro?

    Yes, and usually deeper. Vajro's connector is a fixed shape; Fastshot generates the integration against your store's actual Shopify schema, which means metafields, customer tags, and Customer Account API flows are first-class instead of bolt-ons.

    What about the billing reliability issues some Vajro users have reported?

    The partial-payment and undercharging issues that have appeared on r/shopify are template-connector edge cases — they happen when a builder tries to abstract every store's checkout into the same code path. Fastshot generates the order flow against your specific store, which removes that class of bug because the integration code is store-specific from the start.

    Can I migrate my Vajro app's product catalog and customer base?

    The catalog and customers live in Shopify, not in Vajro — so there is nothing to migrate. The Fastshot project connects to your store directly. The work is rebuilding the retention behavior with the custom logic that motivated the move, not moving data.

    Does Fastshot work for non-Shopify stores?

    Yes — Fastshot generates React Native apps for any backend you describe. The Shopify positioning is because that is the wedge where the AI-vs-template difference matters most. For non-Shopify retention apps, the same generation flow works against a custom or headless backend.

    Outgrow the Template. Generate the App.

    Fastshot writes real React Native code for your Shopify retention app — drops, loyalty, reorders, custom flows. No template ceiling. No surprise billing edge cases.
