Compare · vs other checkout apps

One install replaces five apps.
The math is brutal.

Most Plus merchants stack 3-5 single-purpose checkout apps — one for badges, one for upsells, one for address validation, one for fields. Checkout Ninja consolidates all of them under a single $99/mo install.

App-by-app math

The stack you're paying for — broken down.

Five typical apps a Plus merchant has installed. Each does one job well. Each charges separately. Each upgrades on its own schedule. Checkout Ninja absorbs all of them.

App What it does Cost → Ninja replacement
Trust Badges App Trust badges + payment icons $12/mo Trust Badge + Payment Icons blocks
Custom Fields Plus Gift notes + B2B fields $19/mo Custom Fields blocks (7 types)
Address Validator Pro Real-time address checks $25/mo Address Validation API (Deluxe)
Checkout Upsell+ Post-purchase + at-checkout upsells $39/mo Checkout Upsell block (Deluxe)
Free Ship Bar Pro Threshold progress meter $14/mo Free Shipping Bar block
Total stack cost 5 separate vendors $109/mo One Ninja install: $99/mo

Saved monthly: $10 · Saved per year: $120 · Plus the hours not spent managing five vendors.

Four reasons to consolidate

The case against a five-app stack.

Beyond the dollar savings, here's what consolidation actually buys you.

01

One bill, not five

Five apps × averaged $22/mo = $109/mo. Ninja Deluxe at $99/mo saves roughly $10/mo — and that's before you count the vendor-management overhead.

02

One render, not five

Five checkout-extension apps means five separate runtime injections, five sets of styling, five potential layout collisions. Ninja's blocks render in a single coherent pass.

03

One vendor, not five

When something breaks, you don't play vendor ping-pong figuring out who owns the bug. One support inbox, one SLA, one roadmap.

04

One upgrade path

Shopify ships theme updates and checkout-extension API updates constantly. Maintaining 5 apps against those updates is a quarterly headache. One app is one upgrade.

FAQ · Switching

Questions before consolidating.

Four things merchants ask before switching from a multi-app stack. If you have something specific to your setup, our team will help you map it.

  • What if I already have those apps installed?

    Uninstall them one at a time after replacing each block in Checkout Ninja. Most merchants do the swap over 2-3 days: install Ninja, replicate the active blocks, run side-by-side for an hour to confirm, then uninstall the old apps. No checkout downtime.

  • Can I keep one specialized app and use Ninja for the rest?

    Yes — most checkout-extension apps coexist. We test against the top 20 most-installed checkout-extension apps every quarter. If you find a conflict, our team will reproduce + fix or refund.

  • Does Ninja have every block other apps offer?

    We cover the 24 most-installed block categories on the App Store, which addresses 95% of real merchant requests. If there's a niche block we don't have, our team builds custom blocks for Pro+ merchants on request — typically 5-7 days.

  • What's the catch?

    We're Shopify Plus only. We don't support legacy checkout.liquid. We don't support stores below Plus tier. If you're on Basic/Shopify/Advanced, you can't use us. That's the catch.
