I Rebuilt Yahoo Pipes in a Weekend - Here's How Kiro Made It Possible

Remember Yahoo Pipes?

Back in 2007, it was revolutionary — a visual way to mashup data from RSS feeds, APIs, and websites without writing code. Then Yahoo killed it in 2015.

Last weekend, I brought it back. And I had help.

Meet Pipe Forge

Pipe Forge is a modern resurrection of Yahoo Pipes — a visual data pipeline builder for today's web.

🔗 Try it: pipeforge-480308-ab122.web.app

📦 Source: github.com/swarajdhondge/pipeforge

Features:

• 20+ operators (Fetch JSON/RSS/CSV, Filter, Sort, Transform, Regex, and more)
• Visual drag-and-drop editor
• Real-time schema propagation
• Template library (GitHub repos, Reddit feeds, weather data)
• Social features (browse, fork, like public pipes)

All built in a weekend. Here's the secret: Kiro.

What is Kiro?

Kiro is an AI coding assistant, but calling it that undersells it.

I've used Copilot, ChatGPT, Claude — they're great for autocomplete and answering questions.

Kiro is different. It doesn't just write code. It understands your entire project. It thinks about architecture. It catches edge cases you didn't consider.

Let me show you.

The Moment That Blew My Mind

After building 20+ operators, I had a problem. Some templates were breaking with cryptic errors. Users would connect operators that shouldn't work together, and the error messages weren't helpful.

I asked Kiro:

"Check all operator permutations — if this input type goes to that operator, does it break?"

What happened next was insane.

Kiro:

1. Analyzed every operator file (15+ files)
2. Built a compatibility matrix showing valid vs invalid chains

3. Found 3 bugs I didn't know existed:

   • Transform operator wasn't using its path config for nested data
   • A template had replacement instead of replace (wrong config key)
   • Domain whitelist was missing APIs the templates needed

4. Fixed all of them with proper error handling

Here's the matrix Kiro generated:

Operator	Array	Object	Primitive
filter	✅	❌ error	❌ error
sort	✅	❌ error	❌ error
transform	✅	✅	❌
string-replace	✅	✅	❌
truncate	✅	❌ error	❌ error

And it added helpful error messages:

"Sort operator requires array input, received object.
Make sure the upstream operator outputs an array of items."

That's not code generation. That's systematic debugging at scale.

How Kiro Changed My Development Approach

Before Kiro:

1. Write code
2. Run it
3. See error
4. Google the error
5. Stack Overflow
6. Try 5 different solutions
7. Eventually fix it
8. Repeat for next bug

After Kiro:

1. Describe the problem
2. Kiro analyzes the entire codebase
3. Root cause identified
4. All related edge cases found
5. Everything fixed systematically
6. Move on

The 3 AM CI/CD failure? Kiro found it was TypeScript config incompatibility + 6 unused variables. Fixed in 2 minutes.

The operator chain bugs? Found and fixed across 15 files in one session.

Kiro doesn't replace thinking. It amplifies it.

Final Thoughts

Yahoo Pipes was ahead of its time. Kiro helped me bring it back — modernized for 2025.

What I learned: The right AI tool doesn't just speed you up. It changes what's possible in a weekend.

If you're building something ambitious, give Kiro a try. It's not just an assistant — it's a development multiplier.
