An open-source-first strategy prioritizes open-source software as the default choice before considering proprietary SaaS platforms.
This approach helps organizations reduce recurring costs, avoid vendor lock-in, and maintain full control over their data and infrastructure.
Today, many well-known SaaS platforms have mature, production-ready open-source alternatives that deliver comparable features without subscription-based pricing.

- Full control over data, hosting, and customization
- Long-term cost predictability
- Flexible deployment: on-premise, cloud, or hybrid
An open-source-first approach does not mean rejecting proprietary software entirely.
Instead, it ensures proprietary tools are used only when they deliver clear and irreplaceable value.
