Zero Installation. Zero Vulnerabilities.
Built from the ground up prioritizing developer security, client-side execution, and performance.
100% Private Data Stream
Hardware serial packets and telemetry never touch our servers. Every byte flows directly between your USB port and the browser runtime.
Native Web Serial Engine
Leveraging standard Chromium hardware APIs to access COM ports, FTDI chips, CH340, CP2102, and native USB MCUs with minimal latency.
Cross-Platform Support
Runs seamlessly on Windows, macOS, Linux, and Chromebooks without installing proprietary drivers or bulky native IDEs.
