Open Source Graphic

By staying at the forefront of emerging technologies with a strong focus on open-source development, we upskill your teams with a shared mindset of engineering excellence.

Why use Open Source?

Community Support Icon

Community support

Open source technologies are supported by knowledgeable and resourceful communities. Their collective contributions result in more robust, innovative and faster solutions. Furthermore, allowing open source communities to review the code and propose improvements increases security and reliability.

Full Control Icon

Full control

Using open source technology means transparency and access to the code, which allows faster bug fixes and custom feature development. Clients are no longer dependent on tech vendors and gain full control over the code base.

Attract Talent Icon

Attract talent

Opening up the code base is a channel engage with exceptional engineers in the community. It also allows in-house talent to showcase their individual contributions, giving visibility to both the team and to the company.

Open deliverables

YLD clients are fully in control of how their software is developed - whether is proprietary, open source or a mix of both. Proprietary deliverables are critical, specific to the business and are generally unavailable to the public. Open deliverables are abstract - not business specific - and are accessible to the community.

By choosing to open up appropriate parts of the code, YLD clients can harness the vast resources of the open source community and contribute back to it, facilitating rapid, mutually beneficial innovation.
