Open-Core Licensing
Transparent core technology, polished commercial applications
Core Principles
Transparency
Every line of code is auditable. Users can verify our privacy claims, security implementations, and functionality.
Security
More eyes on the code means faster bug discovery and fixes. Community-driven security is stronger than closed-source.
Community
Contributors improve our code, report bugs, suggest features, and become advocates for our products.
Innovation
Open source enables forks, integrations, and extensions that we couldn't build alone. The ecosystem grows organically.
