What is Cerb?

Cerb enhances the productivity of online teams with web-based collaboration and automation tools:

  • High-volume email management that scales to millions of conversations per year.

  • Shared mailboxes that provide a single point of contact for clients no matter who is on duty.

  • Bots for creating powerful, event-driven, automated behaviors from a web browser without any computer programming experience required.

  • Custom shared workspaces to foster team collaboration.

  • Dashboards for real-time reporting, monitoring, goal tracking, and operational intelligence.

  • Project boards for coordinating tasks and visualizing the current progress.

  • Connected accounts for integration with third-party apps and services.

  • Contact management for tracking important details and nurturing customer relationships.

  • Notifications for keeping the right people informed about activity on any record.

  • Task management for organizing, prioritizing, and delegating units of work.

  • Knowledge management for distributing accumulated experience.

  • Broadcasting of targeted, personalized messages to thousands of contacts with segmentation and dynamic templates.

  • Mobile functionality for remaining productive while away from your desk.

  • Devblocks, a plugin-driven web development framework for rapidly implementing new functionality.

  • A library of browser-installable plugins for extending functionality and integrating with other applications and services (Facebook, Twitter, Twilio, Slack, Freshbooks, Amazon S3, JIRA, HipChat, etc).

  • A REST-based API for automation and integration with third-party applications and services.

  • Webhooks that trigger bot behaviors in response to external events (survey submitted, invoice paid, Slack /command, etc).

  • Portals for building customer-facing online communities around your brands.

  • ... Time tracking, call logging, opportunity management, and much more.

Cerb has continuously evolved for more than 16 years based on community feedback from thousands of teams.

The software is distributed under the Devblocks Public License as a commercial open source project. The full source code is publicly available on GitHub.

Licenses are based on the maximum number of workers able to log in at the same time (i.e. seats). The software can be deployed on independent servers, or as a fully-managed, cloud-based service.

Cerb is developed in the PHP programming language. Relational data is stored in MySQL. See the credits for a full list of third-party libraries, resources, and contributors.
