Thousands of goroutines? Goroviz automatically groups similar goroutines, so instead of scrolling through endless stack traces, you immediately see where your application is spending its time. Just attach it to your running Go application and explore everything from an interactive terminal UI.

Hey Product Hunt! 👋
I built Goroviz because debugging goroutine leaks in production Go apps was painful. Tools like pprof give you raw text dumps with thousands of lines - impossible to scan quickly.
Goroviz takes that raw dump, groups identical goroutines by their call stack, and presents them in a clean interactive dashboard. The biggest groups float to the top, so leaked goroutines are immediately visible.
This is the first minimal version, and I have improvements planned. I'd love to hear more.
It's open source, installs in one command, and works with any Go app that has pprof enabled.
Would love your feedback! 🚀
honestly this looks super useful for debugging gnarly concurrency issues, like scrolling through thousands of goroutines in a flame graph is basically a nightmare right now. one thing that would be great is adding the ability to filter goroutines by custom labels or tags you set in your code, so you could jump straight to the ones handling a specific request or user without having to eyeball the stack traces

@eypqkxk Thanks! Great suggestion. Filtering goroutines is definitely a needed feature. I'll look into it. 🙌
the terminal UI choice is genuinely clever, especially the way similar goroutines collapse into a single expandable view instead of just hiding them. feels like something that respects both your time and your screen real estate.

@tarkb3lu Thanks! Glad you liked the grouping approach! 😄
the terminal ui looks great for digging into hot spots. one thing that would help me a lot would be a way to export a flame graph or call tree from the grouped goroutines so i can share findings with my team or drop them into incident reports.

@atakancounbkbi That's a really good idea. Will definitely work on that. Thanks!
