{ shopify_specialists }

We build the parts of Shopify off-the-shelf themes can't.

Retani is a focused Shopify development studio — theme builds, custom apps, mobile commerce, and integrations. Four specialties. No SEO decks, no ad spend, no scope creep.

what we build

Four files. That's the whole stack we work in.

theme.liquid
app.tsx
mobile.swift
sync.graphql
Theme development

Sectioned, mobile-first themes built in Liquid — from OS 2.0 rebuilds to pixel-perfect custom designs that don't fight the platform.

why so narrow

We turned down SEO, paid ads, and email marketing to go deeper on the four things merchants actually need built right.

most shopify agencies

Theme + apps + SEO + ads + email + CRO + migrations + analytics, one team stretched across all of it.

retani

Theme + apps + mobile + integrations. The technical build, done by people who only do the technical build.
