    Only npm and NuGet carry first-party BuiltWith packages. The PyPI package `builtwith`
    (1.3.4, 2020-06-17) is a third-party scraper by richardpenman and the npm package
    `builtwith` (1.0.2, 2017-09-05) is a third-party scraper by ecrmnn - neither is BuiltWith
    Pty Ltd and neither is recorded as official below.
packages:

  note: First-party CLI; also ships a local MCP stdio server via `bw mcp`. Command surface in cli/builtwith-cli.yml.
- language: javascript
  registry: npm
  name: '@builtwith/mcp-server'
  url: https://www.npmjs.com/package/@builtwith/mcp-server
  install: npx -y @builtwith/mcp-server

  version: 1.8.0

  note: >-
    First-party local-stdio MCP server (author Gary Brewer <gary@builtwith.com>). The repo's
    package.json declares 1.11.1 while npm's latest is 1.8.0, so the published artifact trails
    the source tree; its repository field also points at builtwith/mcp-server while the code
    lives at builtwith/builtwith-mcp.
- language: javascript
  registry: npm
  name: builtwith-tui
  url: https://www.npmjs.com/package/builtwith-tui
  install: npm install -g builtwith-tui
  repo: https://github.com/builtwith/builtwith-tui
  license: MIT
  official: true
  version: 0.2.0
  published: '2026-04-03'
  note: Terminal UI over the BuiltWith API endpoints; published under the builtwith GitHub account.
- language: csharp
  registry: nuget
  name: BuiltWith
  url: https://www.nuget.org/packages/BuiltWith
  install: dotnet add package BuiltWith
  repo: https://github.com/builtwith/BuiltWith-C-Client-API
  official: true
  version: 1.0.1
  published: null
  note: >-
    Client REST API for the BuiltWith.com API. The NuGet registration index exposes only the
    version range (upper 1.0.1); no publish date was returned by api.nuget.org, so `published`
    is an honest null rather than a guess.
- language: javascript
  registry: null
  name: builtwith-node-api
  url: https://github.com/builtwith/builtwith-node-api
  install: null
  repo: https://github.com/builtwith/builtwith-node-api
  official: true
  version: null
  published: null
  note: >-
    First-party Node wrapper published as source only - checked npm for `builtwith-node-api`
    and it is absent (404), so there is no registry metadata endpoint to read a version from.
    Consumers must install from git.
- language: csharp
  registry: null
  name: builtwith-ai-sdk
  url: https://github.com/builtwith/builtwith-ai-sdk
  install: null

  note: >-
    "AI First SDK using BuiltWith MCP"; source-only, no registry listing found on NuGet or npm.
    Its README is the reference BuiltWith points agents at from every docs page.
