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.

Free, Production-Grade Databases. Get setup in minutes. Great for testing and development

Neon: My top choice for AI apps. Database live in <1 sec. Straightforward API for creating / modifying databases and role.

Supabase: Auth integration.

Aiven: Most generous free tier (5GB) and supports both Postgres & MySQL.

I use these for creating a 'one-time-use' database for testing to live client projects.
