What are best examples of well-structured open source products to learn from?

[_____smurf_____]

Hello,

I am working on a product and I would like to get a glimpse on how do teams structure their code, and how do they organize their thoughts with respect to code/stack/production pipeline (e.g. [RASA](https://github.com/RasaHQ/rasa)).

Sinece we are two engineers developing a product, with humbled experience, we would love to see more eye-opening examples that help acquire best practices. Examples can be e-commerce application, preferably a running pipeline in production.

These might provide some insight.

Have a look at Gitlab. The source and the processes are available. I like the way they do things.
