Open Source Software

Freedom and accessibility. These features are what make Open-Source Software so fundamentally amazing, and they're part of the reason why OSS is close to the hearts of everyone working at Invertase.

Almost 80% of businesses use Open-Source Software, and almost all applications utilise Open-Source code. Most people interact with it without even realising. It begs the question: How could anyone not want to build a business around something considered so fundamental to today's society?

Invertase maintains two major cross-platform mobile integrations for Google's globally recognised Firebase cloud services: React Native Firebase and FlutterFire. We've also built indispensable integration tools for the cross-platform mobile ecosystem, from notifications, authentication, mobile-ads and more.

The team is also behind packages such as Denque that are critical to Redis/MongoDB/MariaDB and MySQL libraries for the Node.js JavaScript runtime environment. As well as Melos - a tool on which the Dart ecosystem relies to manage project codebases.

The principals behind Open-Source Software have inspired us to ringfence sponsorship for contributors to ensure its continued development while applying our own expertise, and support OSS-related events in a number of ways. And this is only the beginning. Will you join us on the journey?

Why use Open Source Software?

Open Source Software (OSS) is critical to success because it fosters innovation through collaborative development, ensures greater security with transparent code, and offers flexibility and cost-effectiveness, empowering businesses to adapt rapidly to changing market demands.

Collaborative Innovation

OSS allows developers from around the world to contribute, leading to more innovative and diverse solutions. This collective expertise often leads to more robust and advanced software.

Cost-Effectiveness

With no licensing fees, OSS can significantly reduce costs. This is particularly beneficial for startups and small businesses that may have limited budgets but still require powerful software solutions.

Flexibility & Customization

Open Source Software can be freely modified and customized to meet specific needs. This flexibility allows businesses to tailor the software for optimal performance and integration with their existing systems.

Enhanced Security

The transparent nature of OSS means that its code is open for scrutiny, allowing vulnerabilities to be identified and fixed promptly by the community. This often results in more secure software compared to proprietary alternatives.

No Vendor Lock-in

Using OSS eliminates dependence on a single vendor for support and updates, giving businesses more control over their software and avoiding the risk of discontinued support or unexpected changes in licensing fees.

Community & Support

The OSS community is a vibrant and supportive ecosystem. Users benefit from the collective knowledge and experience of this community, gaining access to a wealth of resources, forums, and documentation for troubleshooting and learning.

Don't just take our word for it

Invertase builds and maintains our own Open Source libraries, as well as those of our clients such as Google. We're publically responsible for the end-to-end development and release process for critial software used by thousands of developers worldwide.
