Bright future for Saas'es

[nader dabit @dabit3]

Something I wanted to see if Claude Opus 4.5 could do: clone a fully functional Billion $ SAAS product and make it at least 100x cheaper.

The first product that came to mind was TypeForm because it's very popular, very expensive, and in theory, very simple.

The result is OpenForm: a polished + functional and Open Source Typeform clone at ~100x less cost, that can be setup and deployed in ~15 minutes. The agent building this ran for ~35 minutes.

Here are the details, technique, and the code:

Built for European traders but works globally.

Quick Start Guide gets you to your first alert in 5 minutes.

No credit card. No hidden fees. Just connect your exchange API (read-only recommended) and start finding opportunities.

[Karlnerd @carlvays]

Features:

🔓 Completely free
🌍 5 languages (EN, FR, DE, ES, NL)
📊 8+ exchanges (Binance, Coinbase, Kraken, Bitvavo, OKX, KuCoin, Bitstamp, Bitfinex)
📱 Telegram alerts
🔒 Encrypted API keys (Fernet/AES-128)
📈 Real-time monitoring

[Karlnerd @carlvays]

What makes the scoring unique:

• 40% Spread Size (bigger = better)
• 25% Liquidity (higher volume = easier execution)
• 15% Transfer Speed (SOL/XRP faster than BTC)
• 10% Fee Impact
• 10% Historical Success

Score 80-100 = Execute immediately 🟢

[Karlnerd @carlvays]

Why I built this:

❌ Tired of checking 5+ exchanges manually
❌ Other tools cost $50-100/month
❌ Raw spread data without context
❌ English-only interfaces

✅ Detectick scores opportunities based on profitability, liquidity, speed & fees
