Lean Canvas captures your business plan on 1 page. It helps to quickly deconstruct your startup idea and focus on essentials: your target audience, their problems & how your product solves them.
Slowbug is a VS Code extension for debugging your code in slow-mo! Slowbug makes it possible to see how the control flows through the code by running it slowly, at your preferred speed, line by line. I find it handy when working on a new codebase.
