Replo vs Instant: AI-Built Pages Beside or Inside Shopify

The short answer: both build store pages from a prompt, a screenshot or a URL, so the decision is where the page ends up. If it has to be part of your Shopify theme, as a page, a section or a product template, Instant publishes the agent's work as theme files, from $39 a month on monthly billing for Starter with 1,000 AI credits (Instant pricing). If you would rather the agent's pages never touch the theme, Replo hosts them on a subdomain, from $119 a month on monthly billing for Starter, or $99 billed annually, with 10,000 credits (Replo pricing). Both checked on 26 October 2026.

What decides it:

1. Turn credits into pages. Instant's docs estimate its Starter allowance at roughly 50 agent tasks a month (AI credits article). For example, four new landing pages a month leaves 50 / 4 = 12.5 tasks per page for the build and every round of edits. Replo prints no credit cost per page; its Usage view shows what each month spent (Replo billing guide).
2. Check the theme you run today. Instant publishes only to Online Store 2.0 themes, and an older theme fails with an upload error (publishing article). Replo leaves the theme alone and connects to your Shopify catalogue, cart and checkout instead.
3. Choose the measure before the first page. Orders per session on each campaign page. An Instant page is a Shopify page, so Shopify reports both halves; a Replo page reports traffic in Replo's Insights and GA4 and orders in Shopify (Replo analytics guide).

Where they differ

Theme files or a separate site

Instant compiles the layout into Liquid, CSS and JavaScript and uploads it to your theme: pages at /pages/handle, sections into the theme editor, templates onto the products you assign (publishing article). Replo's agent pages are server-rendered React apps on Cloudflare's edge, which its docs say cannot be uploaded into a Liquid theme, so they live at their own address (subdomain guide). One gives you pages that behave like the rest of the store. The other gives you pages the store cannot slow down or break.

What comes with the plan

Instant packs store-building pieces into its tiers: 10 theme sections and 3 product templates on Starter, cart drawers, heatmaps and A/B test sessions from Pro (plans article). Replo's tiers are measured in credits and visitor sessions, 100,000 a month on Starter, with analytics across every published page, and Pro adds onboarding hours, a shared Slack channel and turning ad creative into site content (Replo pricing).

What happens to credits

Instant refills monthly credits and drops what is left; bought credits stay, but are removed if the paid subscription ends, including by uninstalling the app (AI credits article). Replo resets monthly credits too, while purchased credits never expire, and it lets you cap monthly use (billing guide).

One AI step: the agent builds, a draft theme catches it

In Instant, open the Agent from the left sidebar, attach a screenshot of the ad that is winning, and write the brief: the product, the promise, one call to action (Agent guide). The agent builds on the canvas with your brand kit applied; you can undo its last change or revert to an earlier point in the chat.

The human check is where it publishes. On Pro, choose a draft theme in Settings, Shopify, Publishing, publish there, and use View live page to see it through the theme's preview link (draft themes article). A person checks price, variants and every claim against the product before the theme goes live.

That check has a price attached. Instant sends every publish to the live theme unless you pick another, and picking a draft theme is fenced to Pro, so the safe way to review an agent's work costs $99 - $39 = $60 a month more than Starter (Instant pricing).

Try both for free

Instant's Free plan builds and previews every layout type and publishes one page with a Built with Instant badge, but has no AI credits, so the agent is tried during Starter's trial (plans article). Replo's Free plan starts with 1,000 credits and unlimited sites on replosites.com (billing guide). Rebuild one live landing page in each and compare the editing rounds each one needed.

Choose Replo if your job is

• Building a page per ad angle without touching the theme.
• Selling from pages that also check out outside Shopify.
• Running scheduled reports and audits from the same agent.

Choose Instant if your job is

• Having an agent build sections, product templates and pages inside the theme.
• Testing variants and reading heatmaps from a $99 plan.
• Keeping every page on your root domain and in Shopify's reports.

FAQ

Does Instant work with any Shopify theme?

It needs a theme compatible with Online Store 2.0; publishing to an older theme fails (publishing article).

Can a Replo Agent page move into my theme later?

No. Replo's docs describe no path from an Agent page into a Liquid theme; its separate Theme Builder publishes into the theme instead (product overview).

Does Instant's free plan include the agent?

No. Free includes no monthly AI credits; Starter includes 1,000, roughly 50 agent tasks or 100 Studio images (AI credits article).
