What is the most useful (and the most useless) Open Source tool?
Hey PH community!
I was recently reflecting on the open-source projects that bring massive daily value versus those that are just cool, experimental concepts. I'd love to hear what your tech stack looks like.
I'll start with mine:
Most useful - as working in wellness healthcare, my fav right now is Open Wearables. It is incredibly useful because it finally allows me to easily integrate and sync health data across various different wearable devices without a headache. (Fun fact: I just saw they are actually launching on Product Hunt today! You can check them out here: https://www.producthunt.com/products/open-wearables?launch=open-wearables-3
Least useful (but incredibly cool): For this one, I have to go with NMTV (https://www.producthunt.com/products/nmtv). From a generative AI perspective, it’s a fascinating and mind-bending project, but in terms of daily utility? Zero. Still love that it exists though!
Now it's your turn:
What is the one Open Source tool you actually use all the time?
What is a tool that is totally useless or overhyped, but maybe still interesting?

I’d say some niche automation frameworks that promise a lot but take more time to configure than they save. interesting ideas, but not practical for my routine
@gwendolyn_kira I’ve been thinking about this too. For me, Git is unbeatable, I use it every single day without even thinking.
Open Wearables
@gwendolyn_kira @nitesh_kumar98 Git is the right answer. Zero cognitive overhead, infinite daily use. The tools that become invisible are usually the most valuable ones.
Open Wearables
@gwendolyn_kira The setup-to-value ratio is such a good filter for this. Which category were you trying to automate: personal workflow, data pipelines, or CI/CD?
