About Webfunny

Webfunny combines front-end monitoring, back-end application performance monitoring and business event tracking in one system. The monitoring side is aimed at technical teams who want to find and fix production problems, while the tracking side serves business teams who analyze user behavior.

According to its README, a short probe snippet collects errors, performance data and user behavior without changing business code. Features include real-time traffic dashboards with page views and unique visitors, user lookup by ID with behavior replay, and automatic grouping of code errors. Deployment needs only Node.js and supports one-click Docker installation, and a cluster edition is described for very high traffic. The documentation is largely in Chinese.

Webfunny is released under Apache-2.0 and offers a free community edition for private deployment, plus a paid enterprise edition with source code available for purchase and customization. It suits companies, especially Chinese-speaking ones, that want to keep monitoring data on their own servers.
