From their Github: "We are an open source alternative to [[Mixpanel]], [[Amplitude]] or [[Heap]], designed to be more developer friendly."

They have a [[Deploy To Heroku]] they recommend as the easiest way to [[selfhost]].

They consider themselves [[OpenCore]]: the core product is [[MIT License]], but they have proprietary extensions and a proprietary enterprise license for a certain directory. They also maintain a mirror of just MIT code at posthog/posthog-foss.
