🚀 Day 1 of BuildHub: I built this entire platform in 2 weeks using AI tools (Claude + GPT-4). I have zero engineering background — I work retail 10+ hours a day.
The stack: Next.js 15, React 19, Prisma, Neon PostgreSQL, Vercel.
Total lines of code written by hand: approximately 0.
Total lines of code generated and reviewed: 15,000+.
If you think you need a CS degree to build a platform, you don't. You need curiosity and AI.

📊 BuildHub stats after launch:
• 28 interactive tools
• 4 sandbox modes (iframe, Sandpack, API, external)
• Full i18n (English + Traditional Chinese)
• Feedback Exchange system with paid bounties
• GitHub Trending auto-updated daily
All built by one person. The future of solo development is here.

🤯 The hardest part of building BuildHub wasn't the code — it was the cleanup.
I deleted 5,518 lines of legacy code in one day. Old SEO tools, dead routes, orphaned components.
Lesson: Code is disposable. What matters is the architecture and the learnings you keep.

🚀 Welcome to BuildHub!
I'm MoLink, and I built this platform as a solo founder using AI tools (Claude, GPT-4, and a lot of coffee ☕).
BuildHub is a community where developers can:
• Share tools and projects
• Let others try them right in the browser
• Exchange honest feedback — free or paid bounty
This entire platform was built in one sprint — from cleanup to launch — with AI-assisted development.
I'd love your feedback! Try out the tools in /explore, post what you're building, and let's help each other ship better products.

Encode text, decode Base64, handle file uploads — all in the browser. Supports Unicode.

💭 Question for developers:
If you could get 5 minutes of honest feedback on your side project from another developer, what would you want to know?
I'm building a Feedback Exchange system on BuildHub where devs can trade feedback or pay bounties for detailed reviews. Curious what matters most to you.
🤔 Unpopular opinion: Most developer tool websites make you read a README before you can try the tool.
What if you could just... try it? Right in the browser? No install, no sign-up, no git clone.
That's what BuildHub's sandbox does. Every tool has a live demo you can use immediately.
Am I the only one who thinks this should be standard?
💡 What's one developer tool you wish existed but doesn't?
I'm looking for ideas for the next tools to build on BuildHub. Bonus points if it can run entirely in the browser.

📝 TIL: Next.js 15 App Router + cookie-based i18n
Instead of /en/ and /zh/ URL prefixes, I use a single URL with a locale cookie. Server components read the cookie and render the correct language.
Pros: No route duplication, clean URLs
Cons: Can't have language-specific URLs for SEO
For a dev community with <1000 users, this tradeoff is worth it.

⚡ How I set up auto-translating tool descriptions with GPT-4o-mini:
1. Tool author writes description in English
2. Admin API triggers batch translation
3. GPT-4o-mini translates name + description + longDescription
4. Result stored in a translations JSON field
5. Frontend reads translation based on locale cookie
Cost: ~$0.01 for all 28 tools. Translation quality: surprisingly good.

🔐 NextAuth v5 (Auth.js) tip:
If you're getting redirect_uri_mismatch with Google OAuth, check TWO things:
1. Authorized JavaScript Origins: both www and non-www
2. Authorized Redirect URIs: both www and non-www + /api/auth/callback/google
This took me 2 hours to debug. Don't be me.

🦕 Fun fact: The BuildHub mascot is a sleeping dinosaur named MoLink Dino.
Why a sleeping dino? Because the best tools are the ones that work while you rest.
Also because I'm lazy and I think that's a superpower. Lazy people find the most efficient solutions.
