Built a Python Playground that visualizes data structures, concurrency, and full memory analysis in real time

Hey r/PythonLearning ,I’ve been working on an online Python playground that goes a bit beyond the usual “run and see output.” It actually visualizes:

  • Data structures
  • Concurrency
  • Complete Memory analysis (you can literally see which variables escape to heap vs stay on stack, with the compiler’s decisions highlighted)

It’s at: https://8gwifi.org/online-compiler/ I made it mostly for my own learning and debugging, but I figured some of you might find it useful too — especially when teaching, onboarding, or just trying to really understand what the runtime is doing under the hood.

Would love any feedback, bug reports, or feature ideas. It’s still a work in progress but already helped me catch a few sneaky escape-analysis surprises in my own code.Let me know what you think!

Fascinating! It looks eerily similar to my execution schema on datadriven.io. Funny to see how similarly we approached this! Trying to come up with a single frame-based execution animation for every possible algorithm+data type was very challenging. Mine excels in debugging. Yours excels in code understanding. Bravo!

Yep & you did a good job too keep it up
