WhatAreYouBuilding.AI is a free, worldwide directory of independent builders and the products they ship. A listing gives you three things a landing page on its own does not: a do-follow link back to your site, a page that AI assistants and agents can read through an MCP server and an open JSON API, and a place investors already look when they want to know who is building what, where, and who is raising. Listing is free, takes a minute, and every submission is read by a person before it appears.
wayb lists independent builders — indie hackers, solo founders, bootstrapped and venture-backed small teams — and the products they are shipping. It is organised by country, category and funding stage, so it answers "who is building AI tools in Israel" or "which bootstrapped SaaS founders are raising" rather than "what launched today".
Three ways, and none of them is a launch-day spike. A do-follow backlink from a real page to your site, which search engines count. A record of your product in a place AI assistants can read, so an assistant asked for tools like yours has something to cite. And a standing audience: investors, other builders, and people browsing a category rather than a feed.
Assistants answer from what they can read and cite. Two things make a product readable: pages that state plainly what it does and who it is for, and presence in sources an assistant already reaches for. This directory is one of those sources — it publishes an llms.txt, an open JSON API and an MCP server that any agent can query without a key, so a listing here is a machine-readable record of your product rather than a screenshot of one.
Yes. Create an agent token on your listings page and paste it into Grok Bot, Claude or Cursor, and the submit_product tool adds the listing on your behalf. It goes into the same review queue as anything submitted by hand.
No. Listing is free and stays free. Sponsorship exists separately — the rails beside the directory are paid placements — and it buys position beside the listings, never a position in them or on the leaderboard.
Engagement on this directory, and nothing else: people who opened a listing, people who left it for the builder's site or accounts, people who shared it, and verified backlinks. Every axis counts distinct people per day rather than events, so sending more traffic at it is not a strategy. It is not revenue, not users, and not quality.
Builders looking for what else exists in their category, investors browsing by country and raising status, and increasingly agents — the same catalogue is served to an MCP client as to a browser.
A product name, one sentence about what it does, a link, a category and a country. Funding stage and whether you are raising are optional, and "would rather not say" is a real answer that is reported as such rather than as a no.
