Best used with an AI agent

40+ live apps, open data APIs, MCP servers, and 200+ guides - more than anyone wants to click through. Point your AI here and it reads the whole map and does the work: finds the tool, pulls the data, runs the analysis, and hands you the links.

Here for the open-source code? Your agent finds the right repo for you - and can even clone and deploy it.

Prefer to explore on your own? Go right ahead.

Help me [your task]. Surface the exact links; where there is an API or MCP, call it directly; and if I want to self-host, find the repo and help me deploy it.

Why 3 versions?

Both overlap today...but agent gets exclusive features soon, and would be consolidated with Suite.

This is a build-as-you-go tool. Right now, CAGR is point-to-point (not a fan - too sensitive to endpoints). Rolling metrics & ML forecasts coming soon.
