40+ of the best open-source tools to build your startup

For startups, finding the right tools to build and deploy their applications can be a daunting task. With limited budgets and resources, it's crucial to make the right choices that will drive the business forward without breaking the bank.

The open source community offers a vast array of tools and projects that can help builders to launch their applications quickly and efficiently. Supporting open source projects is not only cost-effective but also encourages collaboration, innovation, and knowledge sharing among developers. Open source projects are often maintained by passionate volunteers committed to creating high-quality, reliable software that can be used by anyone. Additionally, open source software is transparent and can be audited by anyone, reducing the risk of security vulnerabilities.

By using open source tools, startups can reduce their costs, build better software, and contribute to the broader tech community.

In this post, we'll explore some of the best open source projects available that can help startups get up and running in no time. You can also find on Scaleway's Github what we are currently working on.

Where to deploy?

If you are looking for the proper ally to deploy your project on, you might want to look into our range of Virtual Instances. We divided in four main categories to help you navigate among all the different specs.

Learning

The Instances from the Learning range are perfect for small workloads and simple applications. They are built to host small internal applications, staging environments, or low-traffic web servers.

Cost-Optimized

The Cost-Optimized range balances compute, memory, and networking resources. They can be used for a wide range of workloads - scaling a development and testing environment, but also Content Management Systems (CMS) or microservices. They're also a good default choice if you need help determining which instance type is best for your application.

Production-Optimized

The Production-Optimized range includes the highest consistent performance per core to support real-time applications, like Enterprise Instances. In addition, their computing power makes them generally more robust for compute-intensive workloads.

Workload-Optimized

Expanding the Production-Optimized range, the Worload-Optimized range will be launched in the near future and will provide the same highest consistent performance than the Production-Optimized instances But they will come with the added flexibility of additional vCPU:RAM ratio in order to perfectly fits to your application’s requirements without wasting any vCPU or GB of RAM ressources.
