Lines where the two differ have a tinted background and bold values. Where the data itself says which value is better (more marketplaces, a larger figure of the same marketplace, a fresher release, a verified mark on a marketplace that lists both), the better one is also marked green with ▲ and the worse one red with ▼. Where it runs, the transport, the tools, the settings, hooks, the bundle's parts, the licence and the week's changes are marked only as different: more or fewer is not better in itself.
What each says it does
Program Integrity Alliance
An MCP server to help make U.S. Government open datasets AI-friendly.
curiosity-stack
Curiosity Stack turns any technology signal, market theme, or global event into a structured 6-layer value chain breakdown — through Socratic conversation, not summaries. Each layer builds on the previous: Signal → Mechanics → Cause Tree → Solution Space → Build Requirements → Value Chain Actors → Research Landscape. The India Proxy Agent runs a mandatory sourcing checklist across NASSCOM Deep Tech, DPIIT Startup India, GeM portal, BSE SME / NSE Emerge, and 12 curated India VC portfolio pages — surfacing listed, SME-listed, and private Indian companies at each layer before they appear in mainstream coverage. Includes: Scenario Library (18 pre-built topics), Watchlist with trigger alerts, Thesis Stress Test, Decomposition Library, and Domain Knowledge registry for seeding pre-coverage companies.
