What Shopify apps does Knix use?

Joanna Griffiths founded Knix to solve the postpartum + period-leakage problem that mainstream underwear had ignored for decades. The brand built genuine category leadership in leakproof underwear before competitors (Thinx, Saalt, Modibodi) arrived. Acquired by Essity (the Swedish hygiene + health conglomerate) for $400M in 2022.

What this stack reveals

Knix runs 11 signature-matched apps plus 12 unidentified theme app extensions / App Proxy routes — that's a brand with a deep enterprise stack where many apps inject without leaving a name-recognisable signature. Common in Shopify Plus tenants at this scale because checkout extensions + headless integrations don't always emit the CDN hosts that smaller installs do.
