Hybrid (Hyvä + PWA Studio) — anyone actually doing this?

Rarely, and only for very specific multi-brand setups. Real cases I’ve seen:

• Multi-brand parent — flagship D2C brand on PWA Studio (with native apps), B2B back-office portal on Hyvä on a separate Magento instance. Two surfaces, two stacks, two dev teams, shared product data sync.
• Regional split — North-American storefronts on PWA Studio (where the React team is based), EMEA storefronts on Hyvä (where the Magento + Tailwind team is based). Same backend, different frontends per region.

What I haven’t seen work: trying to run both Hyvä and PWA Studio on the same store / same domain. The maintenance burden compounds, the dev team gets pulled in two directions, and you end up paying 1.5x the cost of either stack alone. If you find yourself drafting a "we’ll do both" plan, that’s usually a sign the underlying decision wasn’t made — pick one and commit.
