Integration Is the Product Now. Finally.

Smashing Magazine put it plainly: users don't need more tools, they need seamless integrations. That's an editorial take, but the product releases this week made it structural.

Resend — one of the cleaner transactional email products built in recent years — is now on the Vercel Marketplace. Vercel and Shopify are jointly rebuilding Hydrogen, the React-based commerce framework. These aren't partnerships announced in a press release. They're integrations embedded into the deployment and development loop itself.

The implication is straightforward. A founder building a Shopify storefront no longer needs to treat their frontend infrastructure and their commerce platform as separate concerns managed by separate teams. A developer adding transactional email doesn't leave their deployment context to wire up a third-party service. The work stays in one place.

This is what platform maturity actually looks like — not more features, but fewer context switches. The cost of integration used to fall entirely on the builder. The platforms are starting to absorb it.

For agencies and studios, this changes the scoping conversation with clients. "Which tools do you use" is becoming less relevant than "which ecosystems are you already inside." The integration layer is where the real lock-in lives, and it's worth being deliberate about which one you build toward.

Composability was always the promise. It's starting to look like the reality.
