Open Source Licenses

Quizzer is built using various open source software and libraries. This page acknowledges the open source projects and their respective licenses that make Quizzer possible.

1. Our Commitment to Open Source

Quizzer values the open source community and is grateful for the many excellent open source projects that power our platform. We are committed to respecting open source licenses and contributing back to the community where possible.

This page lists the major open source dependencies used in Quizzer along with their licenses. For a complete list of all dependencies and their licenses, please refer to your package manager's license report (e.g., pnpm licenses).

2. Our Open Source Philosophy

At Quizzer, we believe that education and technology should be accessible to everyone. This principle extends to how we approach open source software. We're built on the foundation of countless open source projects that enable us to create a powerful, scalable, and innovative learning platform.

Open source software represents the collaborative spirit of the global developer community. It embodies the values we hold dear: sharing knowledge, fostering innovation, and removing barriers to access. Just as we're committed to making education free and accessible, we recognize and respect the open source community's commitment to making powerful tools available to all.

Why Open Source Matters to Us

The open source movement aligns perfectly with our mission. Open source software:

  • Democratizes access to powerful tools and technologies
  • Enables rapid innovation through collaborative development
  • Reduces costs, making quality software accessible to startups and educational institutions
  • Fosters transparency and trust in the software we build
  • Creates a global community of developers working toward common goals

By leveraging open source technologies, we can focus our resources on building unique educational features rather than reinventing foundational tools. This allows us to deliver more value to students and educators while contributing to the broader ecosystem.

How We Use Open Source

Quizzer utilizes a wide range of open source libraries, frameworks, and tools across our entire technology stack. These include:

  • Web frameworks and libraries for building our user interface
  • Database tools and ORMs for managing educational data
  • Authentication and security libraries to protect user information
  • UI component libraries for creating accessible, beautiful interfaces
  • Real-time communication libraries for our multiplayer quiz rooms
  • Validation and type-checking tools to ensure code quality
  • Animation libraries for creating engaging user experiences

Each of these tools is carefully selected based on its quality, community support, and alignment with our technical and educational goals. We ensure that all open source software we use is properly licensed and that we comply with all license requirements.

Our Commitment

We are committed to:

  • Properly attributing all open source software we use
  • Complying with all license terms and requirements
  • Contributing back to open source projects when possible
  • Supporting the open source community through bug reports, feature requests, and code contributions
  • Maintaining transparency about our dependencies and their licenses

We recognize that Quizzer wouldn't exist without the incredible work of the open source community, and we're grateful for every line of code, every documentation page, and every contribution that makes our platform possible.
