The backstory
A few weeks ago I was using a no-code platform to build my product. The platform restored an old checkpoint without warning and I lost 2 weeks of work overnight.
So I did what any sensible person would do: I started over, but this time building something I actually own.
What I built
Webintel is infrastructure for developers and AI agents to handle real-time price and stock change signals.
The model is simple:
- Your app detects a price or stock change
- You call our API with the event
- We meter it, charge $0.003, and fire your webhook instantly
You focus on detection. We handle the pipeline.
The tech stack
- Node.js + Express API hosted on Railway
- Supabase for the database
- Stripe for metered billing
- npm package:
npm install webintel - MCP server for AI agents:
npx @adela_c/webintel-mcp - OpenAPI spec at api.webintel.io/openapi.json
The honest part
I have zero coding background. I built this entirely with Claude's help during my baby's nap times over a few sessions.
I now own everything completely. No platform can roll back my work anymore.
What makes it different
Most price monitoring tools send you an email. Webintel sends your app a webhook.
It's infrastructure, not a consumer tool. The OpenAPI spec means AI agents can use it natively without any custom integration code.
Try it
npm install webintel

Would love feedback from developers — does pay-per-signal make sense for your use case? What's missing?
