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.

Which AI Coder should you use for xlwings Lite (Python in Excel)?

Published: October 7, 2025

Beginners: Gemini 2.5 Pro on aistudio.google.com. Free, simple, 1M context. Covered in my guides at xlwings-lite.tigzig.com

Heavy iterative work: Use proper AI coders that handle large codebases with incremental edits - Claude Code, Cursor, VS Code with Copilot, Gemini CLI.

My default for xlwings Lite: Gemini CLI. Nearly all my xlwings Lite work runs here. Simple setup. Strong free tier, 1M context.

Help your AI Coder: upload the AI Coder Instruction File I share in my xlwings guides. It is designed to make AI Coder's job easier and output reliable.

Why not ChatGPT?

It works fine for quick iterations, but on longer codes it forgets to check the instruction file consistently and the context window fills up too fast.

Claude?

Best AI coder by a wide margin. I use both Claude Code as well as Cursor. But both have been clamping down on message limits - so I toggle between AI Coders depending upon task and messaging quota remaining and typically keep them for more complex pieces.

Gemini CLI?

Not Claude-level, but excellent for xlwings Lite, Python FastAPI backends, simpler HTML-JS UI's. With the Instruction File it works out superbly well for xlwings Lite. And the free tier makes it practical. This is my current setup too.
