What it is

COSS.com is a holding company focused on acquiring and supporting commercial open source software (COSS) projects. Its mission is to provide a sustainable model for open source development by giving projects the resources and support needed to thrive. The company is primarily for developers and organizations that build software, offering them a unified suite of infrastructure services through a single software development kit (SDK).

Main Features

COSS Stack SDK

A comprehensive software development kit designed to provide developers with essential infrastructure services through a single npm package.

  • Unified APIs: Integrates multiple best-in-class services under a single, unified API.
  • Modular Packages: Includes individual packages for core functionalities such as authentication (@coss/auth), video conferencing (@coss/video), calendar integration (@coss/calendar), email (@coss/mail), SMS (@coss/sms), and payment processing (@coss/payments).
  • Simplified Configuration: Managed with a single environment key (COSS_KEY).

Project Incubation & Support

The company acts as a home for open source projects, providing operational and developmental support to ensure their long-term success.

How it works

For Developers Building Applications

Developers can integrate the COSS Stack into their projects by installing the @coss npm package. This provides immediate access to a suite of pre-built infrastructure services, allowing them to focus on writing application-specific code rather than managing underlying infrastructure. The setup is configured using a single .env file with the provided COSS_KEY.

For Open Source Projects

Promising open source projects can become part of the COSS.com portfolio. The company provides the backing and resources needed to help these projects grow, scale, and achieve commercial sustainability.
