Hello Product Hunt! 🚀 I built CastNow because I was tired of the "friction" in traditional screen mirroring—heavy app downloads, forced logins, and privacy concerns. I wanted a solution where I could just open a URL and start casting instantly. Why CastNow? ✅ Zero Install: No apps or plugins. Just your browser. ✅ P2P Privacy: Your stream stays between your devices. No logs. ✅ High Quality: Supports 4K Crystal Clarity with low latency. To celebrate our launch, I’m giving away Free 24-Hour Unlimited Passes to the PH community! Use the link below to grab yours (100% OFF): 🔗 https://minghster.gumroad.com/l/... I'd love to hear your feedback and answer any questions. Happy casting!
