Pick FlowStorm if…

FlowStorm suits Clojure and ClojureScript developers who want to inspect recorded execution, including code running in browsers, Node.js, or React Native. It may also fit developers who need remote debugging or editor integrations.

Pick pyOCD if…

pyOCD suits developers working with Arm Cortex-M microcontrollers who need command-line or IDE debugging, firmware programming, or a Python API for custom tools. It may also suit teams using CI or remote probe access, provided they account for the security and erase limitations.
