Countly

Countly measures how people use mobile, web, desktop and connected device applications, then acts on what it finds through engagement features in the same system. Deploying on premises or in a private cloud settles the data ownership, compliance and infrastructure questions a SaaS-only analytics tool leaves open.

The server runs on Node.js with MongoDB behind it, and its architecture is plugin based, so existing features can be extended or changed and new capabilities added without forking. A documented read and write API covers everything the dashboard shows, and data can be sent in from any source.

This repository holds the server side, which carries most of the product.

• Analytics: session, view and event collection with built-in reports and customizable dashboards.
• Crash reporting: errors from iOS, Android, React Native, Flutter, Node.js, Unity, Java and JavaScript.
• Engagement: rich interactive push notifications for iOS and Android plus in-app rating widgets.
• Remote configuration: adjust an application's logic, appearance and behavior without a release.
• Data Manager: plan and manage events and event segmentations before they sprawl.
• Compliance Hub: consent collection and data subject request management.

Installation assumes a fresh Ubuntu, CentOS or RHEL machine with ports 80 and 443 free, and one command installs every dependency; a bundled shell script and Docker images are the alternatives. The code is AGPL-3.0 with a modified section 7. Countly Lite is free for individuals and small teams under a non-commercial license, while Enterprise and the managed Flex offering add the full suite, SLA and direct support.
