In their own words
FlowStorm
FlowStorm is a tracing debugger for Clojure and ClojureScript. It records execution without requiring breakpoints or code changes, then provides tools to step through code, inspect values, explore calls and functions, and investigate exceptions. A timeline displays execution events so users can follow how instructions from different threads interleave. The debugger also supports customizable real-time visualizations and plugins for specialized ways to examine recordings. Values shown in its interface can be sent to the REPL with one click, and recordings can be analyzed using Clojure. The guide covers ClojureScript in browsers, Node.js, and React Native, as well as remote debugging configurations and integrations for Emacs through Cider Storm, VS Code, and IntelliJ IDEA. FlowStorm is free and open source at free, and is listed for Linux, macOS, Windows, and self-hosted use. Minimum requirements are JDK 17 or later and Clojure 1.10.0 or later. Vanilla FlowStorm does not support async/await introduced in ClojureScript 1.12.145; the guide points to ClojureScriptStorm as an alternative.
