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.

Paste this to Claude Code, Codex, or any AI agent:
Go to tigzig.com and read tigzig.com/llms.txt. It is a practitioner toolkit - 40+ analytics apps, open no-auth data APIs, MCP servers, open-source repos (github.com/amararun), and 200+ build guides. 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.

My analyst and data scientist friends - are you?

And no, I don't mean copy-pasting from ChatGPT. I mean Claude Code, Cursor, Gemini CLI - the agentic AI coding tools.

What they let you do

Build full analytics apps. React frontends, database backends, multi-user dashboards. Deploy on your company VPN or bundle as single-file HTML. Go way beyond Excel/VBA. Large codebases get done many times faster. Even for ML model work, Mito AI works inside Jupyter - proper agentic iteration.

I've taken client projects I would've declined two years ago. Built www.tigzig.com - a portal with 30+ micro-apps covering database AI, quants tools, GPTs, automations. Right now building a 20-user internal AI tool with React + PHP backend. Pre-AI coders, I couldn't have done this.

I use Claude Code as primary, Cursor as backup, Gemini CLI when I don't need the heavy lifting.

But isn't that a developer's job?

I have spent over 25 years doing models, automations, dashboards. My world used to be SAS, Python, SQL, Power BI. That time is gone. You don't have that luxury anymore.

Where to start

Pay $20/month for Cursor or Claude Code. From your pocket if needed.

Want to test free first? Google Antigravity (antigravity.google) has Gemini 3 Pro + Claude Sonnet 4.5 on free tier. Then move to Cursor or Claude Code. Add in Gemini CLI (free) for lighter work. Mito AI for notebooks.
