probe-webFlash and debug embedded targets from a browser tab

probe-rs compiled to WebAssembly, talking to your debug probe over WebUSB. No install, no server — or the same API against a native probe-rs serve.

Two transports, one API

probe-rs in a Web Worker over WebUSB (Chromium), or a native probe-rs serve over WebSocket (any browser, and Node). Your code does not change.

Flash ELF, bin, hex, UF2 and ESP-IDF images with progress and verify. Stream RTT with defmt decoded in the browser, and semihosting output.

Breakpoints, stepping, call stacks, variables, registers, memory and SVD peripherals, over either transport.

Sixteen framework-agnostic web components, and a Debug Adapter Protocol adapter for Monaco, VS Code for the Web or Theia.

Import a vendor's CMSIS-Pack or .FLM flash algorithm in the browser, so a chip probe-rs does not ship can still be flashed.

The same SDK drives hardware-in-the-loop tests from Node against probe-rs serve, including embedded-test suites.
