Speed you can hold us to

Performance has a contract

Miracle now defines measurable service objectives for real-user responsiveness, Core Web Vitals, API latency, availability, data correctness, accessibility, SEO, and browser resource safety. Fast deterministic checks guard every release, while a broader mobile and desktop suite keeps raw evidence and catches unstable outlier runs.

ChatGPT has its own setup path

The MCP guide now walks through ChatGPT Developer mode, Plugins, the exact Miracle server URL, OAuth scopes, tool discovery, and the first connected-account check. Claude keeps its own connector instructions so each client has a clear path.

Developer docs paint sooner

The Developer Center no longer downloads the signed-in application's large stylesheet. It now inlines a small reviewed style layer, preserves the same design, keeps browser zoom available, and is held to explicit transfer and Lighthouse budgets.
