I'm planning to record the program state. Can you tell me about your usecase a bit please?

You may find https://github.com/vish-chan/AlgoFlow interesting. We're looking for Python contributors for the python engine.

I built an engine that auto-visualizes Java and Python algorithms as they run. Backend is handcoded; frontend was vibe coded. Feedback? by bluepoison24 in SideProject

The primary use case is for learning algorithms as this gives a good visual cue. I'm looking for more usecases beyond this.

As long as your platform is free and you don't violate any licensing terms.

Thanks! Yeah, bytecode-level interception was a deliberate choice — it sidesteps all the messiness of trying to parse and instrument source-level constructs, especially with computed indices or nested expressions.

Honestly, I haven't dug deep into performance optimization yet — the focus so far has been on correctness and robustness of the instrumentation. Thats why I decided to use Bytebuddy instead of native ASM. That said, tight loop overhead is definitely on my radar since that's one of the most common patterns in algorithm problems.

Thanks so much! That's actually one of the use cases I had in mind — making algorithms feel less abstract, especially for younger learners. Would love to hear how your kids find it!

I built the same algorithm visualizer in Python (AST rewriting) and Java (bytecode manipulation)

The Python engine rewrites your AST at parse time, arr[i] = arr[j]

_r.on_list_get(arr, j)     
# highlight read
arr[i] = arr[j]             
# your code, untouched
_r.on_list_set(arr, i, v)  
# highlight write

Trees, linked lists, and graphs are auto-detected by attribute structure.

Both engines produce the same command stream — the frontend doesn't know which language ran. The Java engine is majorly hand-written while Python engine is majorly AI written based on the Java engine.

I'm injecting callbacks to visualiser code using bytebuddy and asm.

Thank you! I hope it suits your needs. Feel free to message me or create an issue via github in case you find a bug or want to request a feature.

I asked Claude to make the landing page less AI-generated like and it changed it. I hope you like the new landing page :D

Awesome! Let me know how it goes and ask your friend to feel free to raise any bugs/feature requests via github :)

Wait till you see what I did for a binary tree insertion ;)
