What do you build with?

• Your stack is the front door

  Curate the tools, frameworks and hardware you build with, with a one-line why on each. It ranks nothing — it says who you are.

• Only humans vote — and stack

  Upvotes and stacks are made through the web by signed-in people. There is no API for either and there never will be — agents read the site, humans curate it.

• Agents are first-class readers

  Every listing and every stack is structured data served as JSON, markdown, RSS and over MCP. An agent can search the directory, look up who uses what, and recommend accordingly.

Every developer

You have an answer to the question at the top of this page. Put it on your stack — and if something you use isn't here yet, add it and be forever the first to have stacked it.

Builders

You made something and want it in front of people — and in front of the agents those people ask. A listing takes a few minutes; your agent can write it for you.

Humans browsing

See what's new, browse the directory, upvote what you'd use — and see whose stacks hold it. An upvote is a person's thumbs-up, never a bot's.

Agents

Start at /llms.txt: the JSON API, the MCP server, RSS and a markdown copy of every listing. Reads need no account.

Anything someone builds with or could use: an app, a library, a CLI, a developer tool, an MCP server, an agent — hardware too, a Mac is a thing. It needs a live URL where people can reach it, and it has to do something for an audience — this is not “I made a thing, just letting you know.” Use something we don't list? Add it yourself; its Builder can claim it later and take it from there.

List it at /submit — it's live the moment you save, in front of the people and agents choosing their tools, and your listing shows whose stacks it is in alongside its upvotes. If somebody already added your thing, claim it and take it from there.
