Is there a platform where you can validate your idea, especially for software?

There are a few platforms that can help validate software ideas before building an MVP. Betalist and Prelaunch.com let you create a landing page to gauge interest and collect emails. Also, communities like Indiehackers, Reddit, and even PH here are great for getting feedback on ideas from other makers and techies. I'd start with a simple landing page MVP, share it in relevant communities, and iterate based on the feedback. Lemme know if you want any other suggestions!
