What's Countly?

Countly is an innovative, real-time, open source mobile analytics and push notifications platform. It collects data from mobile phones, tablets and other internet-connected devices, and visualizes this information to analyze mobile application usage and end-user behavior. There are two parts of Countly: the server that collects and analyzes data, and mobile SDK that sends this data.

This repository includes Countly Community Edition. For more information other versions (e.g Enterprise Edition), see comparison of different Countly editions

Supported devices

Countly supports top-notch devices, including iOS, Android, Windows Phone and Blackberry. You can find a list of officially and community supported Countly SDK libraries here. Each SDK has its own installation instructions.

Installing & upgrading Countly server

Note: If you are updating from v14.08, read instructions here.

You can either download all files from Sourceforge, or get code from Github (this page). We provide a beautiful installation sript (bin/ with countly-server package that installs and configures everything required to run Countly Server.

If you feel like doing things manually, or need to upgrade Countly from a previous version, please take a look at the installation & upgrading articles at

Countly also has Docker support - see our official Docker repository


We develop and test Countly on Ubuntu with MongoDB, Node.js and nginx. Installation script only needs a clean, decent Ubuntu Linux without any services listening to port 80 and takes care of every library and software (e.g MongoDB, Nginx, Node.js, Expressjs etc) required to be installed on Ubuntu Linux.

Countly Community also provides scripts to install Countly on Mac OS X or Debian Wheezy

API & Frontend

API documentation can be found here.

Other important files are frontend/express/app.js (Countly dashboard that runs on Express server), frontend/express/public/javascripts/countly (Contains seperate helper js files for each data visualization), countly.session.js (responsible for calculating session related metrics) and api/api.js, which is Countly write and read API. Waits for write requests from the mobile SDKs and read requests from the Countly js helpers.
