Securing the domain name should be your top priority! If you’re unsure or find a better name later, no problem — but don’t risk using a name before you own the domain. If someone else registers it first, you could lose it or end up paying a hefty price. On the flip side, registering the wrong domain only costs around $10–$15. Worth the peace of mind!
✅ POLL: Do you buy the domain first or build the product first?

Hey Product Hunt 👋 I built ResizeGuy to solve a frustrating problem: uploading a profile picture and having it look terrible on different platforms. Either it’s too big, too small, cropped weird, or pixelated. With ResizeGuy, anyone can resize and crop images to perfection for social media, e-commerce, and content platforms — no design skills needed. Would love your feedback and support!
