API docs

Docs for the people and the agents who use your API. Guides and the API reference at /docs on your domain, in every language of the project.

What it adds

  • apps/docs, built by Blume: guides in MDX, and the API reference built from the OpenAPI document of your operations. A new operation appears in the reference with its own description.
  • The docs at /docs on your main domain: the app rewrites /docs to the docs deployment.
  • Its own llms.txt and a Markdown copy of each page, for agents.
  • Guides in every language of the project. pnpm --filter docs translate writes the missing translations with Claude.

Set it up

pnpm dev also starts the docs on http://localhost:4321/docs, and the app serves them at http://localhost:3000/docs.

To deploy, create a second Vercel project with Root Directory apps/docs and SITE_URL set to the app’s production URL. Then set DOCS_ORIGIN on the app to the docs project’s URL.

Before launch

The docs project is deployed, and /docs on the main domain shows it.

Leave it out or add it later

Leave docs out of --modules to start with one app only. To add the docs to an existing project, ask your agent to use the add-module skill.

Run one command. The CLI asks the rest, and your agent takes it from there.

pnpm create turbinekit my-app
See the prompt

Paste it into an agent that can run commands, such as Claude Code, Codex or Cursor.

Create a new TurbineKit project with me.

TurbineKit (https://turbinekit.dev) is an open-source Turborepo and Next.js starter. Its CLI, create-turbinekit, needs Node.js 24 and pnpm 10 (run `corepack enable` once).

1. Run `pnpm dlx create-turbinekit --help` to see its options.
2. Ask me its questions one at a time, with their defaults: the folder, the product name, one sentence about the product, the company or legal name, the contact email, the languages and the modules. Skip what I have already told you.
3. The CLI only asks questions in an interactive terminal, so run it with my answers as options and `--yes`. Show me the command before you run it.
4. In the new folder, read AGENTS.md. Then do "1. Minimal setup" in SETUP.md, and tick each box you finish.
5. Tell me the URL of the running app, and which services SETUP.md lists next.

No sign-up, no API keys. Needs Node.js 24 and pnpm 10.
