What Pug is

Pug is a product analytics tool for examining behavior inside a product. It turns raw events into six insight types: trends, funnels, retention, segmentation, user flow, and Top K. Teams can review behavior across groups and use person profiles to connect activity over time. Its identify function merges anonymous activity into a unified profile so events can be associated with a person after consent is granted. The Web SDK can capture page views, clicks, scrolls, form submissions, and rage or dead clicks after one initialization. It defaults to cookieless operation and does not write to the device.

Pug is available as managed cloud hosting or as a self-hosted stack. Self-hosting uses a single Go binary backed by PostgreSQL, ClickHouse, and NATS, keeping events on the operator’s infrastructure. Web, Node, and Flutter SDKs are provided, with browser documentation for Next.js, React, Vue, Svelte, and plain JavaScript. Native Android and iOS SDKs are listed as coming soon. Pug is open source under AGPL-3.0; modifications served over a network must be shared under that license. The Open Source plan is free forever with unlimited events and projects. Managed cloud is free during open beta, with no limits and email support; final pricing is to be confirmed before general availability.
