This might work for small software or apps, but I wouldn't risk it with APIs. At the very least, it should be a powerful cloud service that can handle the load. Custom APIs, which various specialists like Binary Studio https://binary-studio.com/api-development/ can now develop, offer higher data security, flexibility, and scalability. And if there are any errors or failures, you have more control over how to fix the problem. I think my point is clear: custom solutions are always about reliability.
I don’t have much experience, so I might not be the best advisor. Probably, I'd say, why create something new when there’s already so much good stuff out there? Plus, it's cheaper and faster.
Ready-made API solution or custom development?
That's always a dilemma for me, and it's not just about the money spent on developing a new product. It also takes a lot of time, and there are already many ready-made solutions you can adapt to your needs. What do you think? Or should we wait and contact developers?
