  npm, PyPI, RubyGems, crates.io, NuGet, pkg.go.dev/proxy.golang.org, Packagist,
  github.com/similarweb, and the Similarweb developer docs (developers.similarweb.com,
  docs.similarweb.com/api-v5)
description: >-
  Similarweb publishes NO first-party client library for its API in any public package
  registry. The developer docs contain no SDK page and no install command — the documented
  integration paths are raw HTTP with an `api-key` header, the hosted MCP server, and the
  no-code connectors (Excel, Looker Studio, Salesforce, HubSpot) catalogued in
  components/similarweb-components.yml. The github.com/similarweb organisation was reviewed
  in full (53 public repositories, 2026-08-13): every repository is internal platform or
  DevOps tooling (statusbay, finala, bbox, homebrew-tap, linq2fb) or a fork of a third-party
  library. None is an API client. The entries below are therefore all community-maintained,
  all unofficial, and all stale — the newest first-party-adjacent thing a developer can
  install is an n8n community node, and the language clients date to 2016.

  maintainer: Dan Wagner (danwagnerco@gmail.com)
  repository: https://github.com/danwagnerco/similarweb
  note: >-
    Community Python client. Last released 2016-03-11 — predates the v3, v4 and v5 REST
    surfaces entirely; targets the retired legacy API. Not usable against the current API.

- language: ruby
  registry: rubygems
  name: similarweb
  url: https://rubygems.org/gems/similarweb
  install: gem install similarweb
  official: false

  maintainer: John McLaughlin, Steven Lai
  repository: http://github.com/johnmcl/similarweb
  note: >-
    Community Ruby wrapper. Last released 2016-03-02; same generation as the Python client
    and equally superseded.

- language: javascript
  registry: npm
  name: n8n-nodes-similarweb
  url: https://www.npmjs.com/package/n8n-nodes-similarweb
  install: npm install n8n-nodes-similarweb
  official: false
  version: 0.1.3
  published: '2025-10-16'
  maintainer: bryceyork
  note: >-
    Community n8n workflow nodes for the Similarweb API. The most recently maintained
    third-party package found, but it is an n8n node package rather than a general-purpose
    client library.

- language: javascript
  registry: npm
  name: similarweb
  url: https://www.npmjs.com/package/similarweb
  install: npm install similarweb
  official: false
  version: 0.1.0
  published: '2022-09-29'
  note: >-
    Community CLI that scrapes Similarweb traffic ranks. Not an API client — it does not
    use the documented REST API or an API key.
