Some technical stacks and platforms will suit your SaaS solution needs depending on the solution you are trying to build, and some will not. Remember that users will only pay for SaaS for as long as they need or want the solution.
That's why it's important to create software that works flawlessly and provides the best experience for your audience, increasing your chances of retaining users. Additionally, your technology should allow you to iterate quickly and release new features frequently so that users are always entertained with new options and possibilities. Depending on the type of solution you offer users, you should consider the best combination of frameworks, programming languages, tools, and other platforms to achieve your goal. Build a data-obsessed team that can help scale your solution.
