For developers just starting out, PostHog is a free way to understand how your product is being used, without having to send any data to 3rd parties.
For enterprise customers, one data security becomes a key concern, or B2C businesses where using a SaaS solution is unaffordable, it's typical to see teams hosting an event capture platform, a data lake, and sophisticated analytics tools. The end result is that data scientists are needed and most developers don't have easy access to product intel. PostHog solves that gap - it lets everyone understand how your product is being used, without having to send data to 3rd parties, even once you have scaled to millions of visitors.
It has a JS snippet that can autocapture events, and pre-built libraries to push backend data to. Build up full user histories, visualize product trends, funnels, and run experiments with new features.

For this CSS Art challenge, I wanted to step out of my comfort zone. While I've used CSS extensively for web apps and websites, I had never built an art piece purely with CSS. I started by diving into codepen and other inspiration sites, getting a feel for what was possible. Eventually, a rough sketch of an office atmosphere in Excalidraw became my guiding vision.
