Questions & Answers

As answered by people managing urur.dev and CodeSandbox.

What makes your product unique?

urur.dev's answer

urur.dev focuses on one thing: validating ideas before you build. Unlike feature request tools (Canny) or launch platforms (Product Hunt), urur.dev lets you test demand at the idea stage — before writing a single line of code. Browse freely, sign in to vote and engage.

Why should a person choose your product over its competitors?

urur.dev's answer

It's simple and free. No signup required to browse ideas. Sign in to vote "Want!" and track ideas you care about. Post your idea, share the link, and see if real people want it — validation in minutes, not months.

How would you describe the primary audience of your product?

urur.dev's answer

Indie developers and solo founders who build side projects. People who've wasted time building something nobody wanted and don't want to make that mistake again.

What's the story behind your product?

urur.dev's answer

I spent 6 months building a side project nobody wanted. Twice. I realized the problem wasn't my code — it was building without validation. So I created urur.dev — the name comes from "uru uru" (売る売る), Japanese for "sell sell." The idea is simple: find your customers before you build, not after. A place where you can test if anyone actually wants your idea before you invest your nights and weekends building it.

Which are the primary technologies used for building your product?

urur.dev's answer

HonoX (Hono + Islands architecture), Cloudflare Pages, Supabase (PostgreSQL + Auth), Vite, Tailwind CSS, and Resend for email notifications.
