Connect to Bluetooth Low Energy devices directly from Safari. WebBLE brings the W3C Web Bluetooth API to iOS — no native app required for each device. WebBLE brings Bluetooth Low Energy (BLE) to Safari on iOS, letting you connect to BLE devices directly from web pages — no dedicated native app needed for each device. HOW IT WORKS WebBLE is a Safari Web Extension paired with a companion app. Once enabled, websites can use the WebBLE JavaScript API (navigator.webble) to discover and communicate with nearby BLE devices. For sites already built with the standard Web Bluetooth API, an optional CDN bridge script (webble.js) maps navigator.bluetooth calls to navigator.webble — just add one script tag. The companion app guides you through a simple one-time setup and provides tools to verify everything is working. KEY FEATURES - Full Web Bluetooth API support: requestDevice(), GATT service and characteristic discovery, read/write operations, and real-time notifications - Batch GATT operations for fast, efficient device communication - Native iOS device picker for secure device selection - Connection persistence across tab switches and brief app suspensions - Optional background sync registrations for alerts and beacon monitoring that you explicitly enable from supported websites - Standalone BLE scanner in the companion app for independent testing - Extension status dashboard with real-time monitoring USE CASES - IoT Dashboards: Monitor and control smart home devices, sensors, and actuators from web-based dashboards in Safari, including optional background alerts for important state changes - Fitness & Health: Connect to heart rate monitors, cycling sensors, and other fitness peripherals through web apps, with optional notifications for tracked measurements - Smart Home: Interact with BLE-enabled lights, locks, thermostats, and appliances via browser-based interfaces - Development & Prototyping: Test and debug BLE peripherals using web-based tools like nRF Connect for Web, without switching between native apps - Education: Build and experiment with BLE projects using web technologies SECURITY & PRIVACY WebBLE is secure by design. Every Bluetooth connection requires your explicit consent through the native iOS device picker. Optional background monitoring is available only when a supported website explicitly registers it and you grant the required permissions. The extension collects no personal data and performs no tracking. Crash reporting via Sentry uses EU-based data residency and captures only diagnostic data (crash logs, performance metrics) that is never linked to your identity. REQUIREMENTS - iOS 26.0 or later - iPhone with Bluetooth Low Energy support - Compatible BLE peripherals INSPIRED BY OPEN STANDARDS WebBLE's API follows the W3C Web Bluetooth specification used by Chrome and Edge on desktop. It provides the same operations — device discovery, GATT read/write, notifications — through the navigator.webble namespace. An optional CDN bridge script (webble.js) translates standard navigator.bluetooth calls so existing Web Bluetooth sites can adopt WebBLE with a single script tag.
