Every Estuary product must meet four non-negotiable criteria — regardless of stack, vertical, or price point. This is what the Standard requires.
A product that loads slowly is a broken product. The Estuary Standard requires 90+ Lighthouse across all four categories — not as a target, as a floor.
We achieve this the same way every time: no jQuery, no page builder runtime, server-rendered output, self-hosted fonts, and less than 3KB of JavaScript on the wire.
Every Estuary product ships with a complete design system — not a theme with some color options. Named design worlds. A full CSS token architecture. Density, motion, radius, and surface controls that stay coherent when changed.
One setting changes everything — and it stays coherent. This is what makes Estuary products feel like $10k websites at a $79 price point.
Answer Engine Optimization is how content gets surfaced by AI search tools — Perplexity, ChatGPT Search, Gemini. Standard SEO is necessary but no longer sufficient.
Every Estuary product ships with structured data built in at the block level. No plugin required. No configuration needed. The schema is part of the product.
No plugin required. No Yoast needed. Schema auto-outputs from the blocks themselves.
Estuary products are built by an engineer, for engineers. The buyer is a developer who will customize this, inherit it, and hand it to a client. That experience is a product decision.
Every Estuary product ships production-ready, extensible, and documented.
