That's +200% from last update made last month. The reason of such a spike is simple: Pizzly got featured in TLDR a massive newsletter for developers.
It's definitely a great channel to get traction. There are over 118 000 readers on that newsletter.
I don't know how much have clicked the link to the GitHub repository, but about 300 of them have starred the repo. That's a 0.25% conversion rate 🤯
