I totally get where you're coming from. Setting up a server for your application can be quite a task, especially if you're just starting out. But hey, don't worry, there are definitely ways to interact with open-source servers without having to set up your own.
One option you might want to explore is using Platform as a Service (PaaS) providers like Heroku or Firebase. These platforms offer server infrastructure that you can use to host your application without having to manage the server yourself. They usually have free tiers which are perfect for getting started.
Another option is to leverage serverless computing platforms like AWS Lambda or Google Cloud Functions. With serverless, you can run your code without provisioning or managing servers. It's a great way to offload the server management aspect and focus more on your application logic.
As for interacting with open-source servers, it really depends on what you're looking to achieve. If you're talking about integrating with existing open-source projects or APIs, you'll need to look into their documentation to understand how to interact with them programmatically.
Regarding your application, I'd be more than happy to give it a whirl and provide feedback. Just let me know how I can access it, and I'll do my best to provide constructive feedback to help you improve it.
Good luck with your project, and don't hesitate to reach out if you have any more questions or need further assistance!
