Product opportunity signal,
as an API
Our agents scan online sources for real demand signals, score every opportunity for confidence, and back each one with source evidence. Consume the signal directly through API, MCP, or SDK.
Live opportunities
Real signal from this week's agent run. No curation, no spin.
Web component extractor for frontend developers
Frontend developers waste time manually copying HTML/CSS from websites to recreate components, lacking a tool to automate extraction with computed styles and font references.
"Pablo shows real demand (33 upvotes, live product). Solves repeated workflow pain. Output designed for AI code assistants (Claude, Cursor), aligns with modern dev tooling. No subscription required but could extend to premium."
UK Solar ROI Calculator – Plug-in Panel Estimator
Homeowners in the UK can't easily estimate how much electricity plug-in solar panels would generate for their specific property before purchasing.
"121 points on Show HN; addresses a newly-legal product category with clear ROI calculation need; uses publicly available LIDAR data; solves a real pre-purchase decision barrier."
Agentic Workflow Durability & Error Visibility
Agentic applications in production fail silently with cascading errors when individual steps (API calls, memory issues) fail mid-workflow, creating invisible failures across distributed agent systems.
"Multiple upvotes (11) and explicit pain point from someone building production agent systems. Author spent a month rewriting jobs as durable execution on DBOS, suggesting others have the same problem. 'Worst war stories' framing indicates widespread issue."
