I Built my SaaS Using Vibecoding (and Why I Chose Claude Sonnet 3.5)

I just launched AllPub.co and built pretty much the entire thing using Vibecoding with Claude Sonnet 3.5. I'm a software architect with just some basic Python knowledge, so this was my first full web app build. Wanted to share my experience!

What I Built

AllPub.co is a tool that lets you write once in your favourite platform or Notion and automatically publish to Dev.to and Hashnode. I'm currently exploring more integrations like Medium, LinkedIn, and others based on what people actually want. No more copy-pasting and reformatting the same article three times.

Why Claude Sonnet 3.5?

I tried a few AI assistants, but Claude Sonnet 3.5 just clicked for me. Here's why:

1. Better code quality - It writes cleaner code that actually makes sense when I read it back​

2. Understands context - When I explained how different publishing APIs work, it remembered and applied that logic across features​

3. Great at debugging - When something broke, Claude was really good at finding the actual problem, not just surface-level fixes​

4. Handles complexity - My app connects to multiple APIs with different formats. Claude handled that without getting confused​

My Tech Stack

1. Next.js (frontend)

2. Tailwind CSS (styling)

3. Supabase (database) will migrate soon!!!

4. Clerk (authentication)

5. Vercel (hosting)

6. Currently: Notion, Dev.to, Hashnode APIs

7. Exploring: Medium, LinkedIn, Ghost, and more

Real Results

The good: Features built in hours, focus on UX and architecture, shipped with zero JS/TS experience.

The challenges: Manual review of rate limiting, learning enough to understand AI output, deciding which integrations matter most.

The Honest Truth

Vibecoding isn’t magic, you still design the system and make key decisions. But you don’t have to be a full-stack dev to ship. Describe the problem, guide the AI, and it writes the code. I’m not a developer, but I did ship my product.

What’s Next

Talking to users to prioritize new integrations. Medium and LinkedIn are top contenders, but I want real feedback.

Questions for You

Anyone else building without traditional dev skills?

What AI assistant are you using?

What publishing platforms would you want to see integrated?

Would love to hear what's working (or not working) for you!
