Description
Paste any recursive JavaScript function and watch it run as a live call tree. You can step forward and back through every call, see arguments go down and return values come back up, and watch the call stack grow and shrink. Memoisation and variables are tracked as you go. Your code runs in a sandbox in your browser, and infinite loops are caught safely. Share a link to any trace or export it as an animation. Free, no sign-up

Could you build this?
Partial Parsing and safely instrumenting arbitrary recursive JavaScript ASTs to track memory, stack frames, and memoization steps inside a visual debugger is a non-trivial compiler/tooling problem.
What it would actually take: Requires using an AST parser and transformer like Babel or Acorn to inject instrumentation hooks at every function entry, exit, variable assignment, and return statement, or running the code in a sandboxed interpreter (like JS-Interpreter). You need to capture execution frames into an event replay log and bind that state to an interactive visualization engine (e.g., D3 or React Flow), demanding compiler and runtime instrumentation expertise.
