Device Posture API: Detect Foldable Screen Posture on Web
The Device Posture API helps web apps adapt to foldable devices by detecting whether a screen is continuous or folded and reacting to posture changes.

Device Orientation Events let web apps read a phone’s real-world tilt and rotation. This demo streams alpha/beta/gamma values, smooths jitter, and maps motion to a 3D box—while handling HTTPS requirements and iOS permission prompts.

The Credential Management API lets your site securely store and retrieve user credentials through the browser’s built‑in manager—no brittle autofill hacks required. In our demo, a successful login stores a PasswordCredential, and a single click later retrieves and auto-fills it for returning users. It’s a progressive enhancement: your form still works everywhere, but supported browsers deliver a faster, lower-friction sign-in. Pair it with proper autocomplete attributes today, and plan for WebAuthn/passkeys to level up tomorrow.
